Flutter Text and Typography

Text is one of the most frequently used UI elements in Flutter. Flutter provides the Text widget for displaying strings and the TextStyle class for controlling typography such as font size, font weight, color, font family, alignment, spacing, decoration, line height, and shadows. The Text widget can also control wrapping, overflow, maximum lines, and text scaling. :contentReference[oaicite:0]{index=0}

1. What Is Text in Flutter?

The Text widget displays a string of text in a Flutter application. It is commonly used for headings, labels, descriptions, buttons, messages, titles, prices, usernames, and other textual information.

Basic Example

import 'package:flutter/material.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        body: Center(
          child: Text('Hello Flutter'),
        ),
      ),
    );
  }
}

2. Understanding the Text Widget

The basic syntax of the Text widget is:

Text(
  'Your text here',
)

A Text widget can be customized using properties such as style, textAlign, maxLines, overflow, softWrap, and textScaler. :contentReference[oaicite:1]{index=1}

Example

Text(
  'Welcome to Flutter Development',
  style: TextStyle(
    fontSize: 24,
    fontWeight: FontWeight.bold,
    color: Colors.blue,
  ),
)

3. What Is Typography?

Typography refers to the visual presentation and arrangement of text. Good typography makes an application easier to read, more consistent, and visually organized.

In Flutter, typography can be controlled through TextStyle, TextTheme, ThemeData, and related text widgets.

Important Typography Elements

• Font family
• Font size
• Font weight
• Font style
• Text color
• Text alignment
• Line height
• Letter spacing
• Word spacing
• Text decoration
• Text shadows
• Text overflow
• Text wrapping

4. TextStyle

TextStyle is used to describe how text should be formatted and rendered. It provides properties for font size, weight, style, color, family, spacing, decoration, shadows, line height, and more. :contentReference[oaicite:2]{index=2}

Basic TextStyle Example

Text(
  'Flutter Typography',
  style: TextStyle(
    fontSize: 30,
    fontWeight: FontWeight.bold,
    color: Colors.deepPurple,
  ),
)

5. Font Size

The fontSize property controls the size of the text.

Text(
  'Small Text',
  style: TextStyle(
    fontSize: 14,
  ),
);

Text(
  'Large Text',
  style: TextStyle(
    fontSize: 32,
  ),
);

Example with Different Sizes

Column(
  children: [
    Text(
      'Small Text',
      style: TextStyle(fontSize: 14),
    ),
    Text(
      'Medium Text',
      style: TextStyle(fontSize: 20),
    ),
    Text(
      'Large Text',
      style: TextStyle(fontSize: 32),
    ),
  ],
)

6. Font Weight

fontWeight controls how thick or bold the characters appear.

Common Font Weights

Example

Column(
  children: [
    Text(
      'Normal',
      style: TextStyle(
        fontWeight: FontWeight.normal,
      ),
    ),
    Text(
      'Medium',
      style: TextStyle(
        fontWeight: FontWeight.w500,
      ),
    ),
    Text(
      'Bold',
      style: TextStyle(
        fontWeight: FontWeight.bold,
      ),
    ),
  ],
)

7. Font Style

The fontStyle property can be used to make text normal or italic.

Text(
  'Italic Text',
  style: TextStyle(
    fontStyle: FontStyle.italic,
  ),
)

Normal text can be created using:

TextStyle(
  fontStyle: FontStyle.normal,
)

8. Text Color

The color property controls the color of the text.

Text(
  'Blue Text',
  style: TextStyle(
    color: Colors.blue,
  ),
)

Using Color with Multiple Properties

Text(
  'Important Message',
  style: TextStyle(
    fontSize: 22,
    fontWeight: FontWeight.bold,
    color: Colors.red,
  ),
)

9. Text Alignment

The textAlign property controls the horizontal alignment of text within its available space.

Common TextAlign Values

• TextAlign.left
• TextAlign.right
• TextAlign.center
• TextAlign.justify
• TextAlign.start
• TextAlign.end

Example

Text(
  'Welcome to Flutter',
  textAlign: TextAlign.center,
)

Full-Width Centered Text

Container(
  width: double.infinity,
  child: Text(
    'Centered Heading',
    textAlign: TextAlign.center,
    style: TextStyle(
      fontSize: 24,
      fontWeight: FontWeight.bold,
    ),
  ),
)

10. Text Decoration

The decoration property can be used to add lines or other decorations to text.

Underline

Text(
  'Underlined Text',
  style: TextStyle(
    decoration: TextDecoration.underline,
  ),
)

Line Through

Text(
  'Deleted Price',
  style: TextStyle(
    decoration: TextDecoration.lineThrough,
  ),
)

Overline

Text(
  'Overline Text',
  style: TextStyle(
    decoration: TextDecoration.overline,
  ),
)

11. Decoration Color and Style

Text(
  'Special Text',
  style: TextStyle(
    decoration: TextDecoration.underline,
    decorationColor: Colors.red,
    decorationStyle: TextDecorationStyle.dashed,
  ),
)

Useful decoration styles include:

• TextDecorationStyle.solid
• TextDecorationStyle.double
• TextDecorationStyle.dotted
• TextDecorationStyle.dashed
• TextDecorationStyle.wavy

12. Letter Spacing

letterSpacing controls the additional space between individual characters.

Text(
  'FLUTTER',
  style: TextStyle(
    letterSpacing: 4,
    fontWeight: FontWeight.bold,
  ),
)

Letter spacing can be useful for headings, labels, buttons, and uppercase text.

13. Word Spacing

wordSpacing controls the additional space between words.

Text(
  'Flutter Text Typography',
  style: TextStyle(
    wordSpacing: 8,
  ),
)

14. Line Height

The height property of TextStyle controls line height as a multiple of the font size. It is useful for improving readability in paragraphs and multi-line content. :contentReference[oaicite:3]{index=3}

Text(
  'Flutter makes it easy to build beautiful applications. '
  'Good typography improves readability and user experience.',
  style: TextStyle(
    fontSize: 18,
    height: 1.6,
  ),
)

15. Font Family

The fontFamily property specifies the preferred font family used to render text. Flutter also supports fallback font families when a requested glyph is not available. :contentReference[oaicite:4]{index=4}

Example

Text(
  'Custom Font Example',
  style: TextStyle(
    fontFamily: 'Roboto',
    fontSize: 24,
  ),
)

16. Using Custom Fonts

Custom fonts can be included in a Flutter project and declared in pubspec.yaml.

Example Project Structure

project/
├── assets/
│   └── fonts/
│       ├── MyFont-Regular.ttf
│       └── MyFont-Bold.ttf
├── lib/
│   └── main.dart
└── pubspec.yaml

pubspec.yaml

flutter:
  fonts:
    - family: MyFont
      fonts:
        - asset: assets/fonts/MyFont-Regular.ttf
        - asset: assets/fonts/MyFont-Bold.ttf
          weight: 700

Using the Custom Font

Text(
  'Hello Flutter',
  style: TextStyle(
    fontFamily: 'MyFont',
    fontSize: 28,
    fontWeight: FontWeight.bold,
  ),
)

17. Font Family Fallback

Flutter allows developers to specify fallback font families. If a requested glyph is not available in the primary font, Flutter can try the fallback families in order. This is particularly useful for multilingual applications and special characters. :contentReference[oaicite:5]{index=5}

Text(
  'Hello नमस्ते',
  style: TextStyle(
    fontFamily: 'MyFont',
    fontFamilyFallback: [
      'Noto Sans',
      'Roboto',
    ],
  ),
)

18. Text Shadow

The shadows property can add one or more shadows to text.

Text(
  'Flutter',
  style: TextStyle(
    fontSize: 40,
    fontWeight: FontWeight.bold,
    shadows: [
      Shadow(
        offset: Offset(3, 3),
        blurRadius: 5,
        color: Colors.grey,
      ),
    ],
  ),
)

19. Multiple Shadows

Text(
  'Shadow Text',
  style: TextStyle(
    fontSize: 32,
    shadows: [
      Shadow(
        offset: Offset(2, 2),
        blurRadius: 4,
        color: Colors.black45,
      ),
      Shadow(
        offset: Offset(-1, -1),
        blurRadius: 2,
        color: Colors.white,
      ),
    ],
  ),
)

20. Text Overflow

Text can sometimes be longer than the available space. Flutter provides the overflow property to control how visual overflow is handled. :contentReference[oaicite:6]{index=6}

Ellipsis

Text(
  'This is a very long text that may not fit inside the available width.',
  maxLines: 1,
  overflow: TextOverflow.ellipsis,
)

This can produce an output similar to:

This is a very long text that may...

Fade

Text(
  'This is a long text example.',
  maxLines: 1,
  overflow: TextOverflow.fade,
)

Clip

Text(
  'This is a long text example.',
  maxLines: 1,
  overflow: TextOverflow.clip,
)

21. Maximum Lines

The maxLines property limits the number of lines that the text can occupy.

Text(
  'Flutter is a UI toolkit for building applications. '
  'This paragraph demonstrates maximum line control.',
  maxLines: 2,
  overflow: TextOverflow.ellipsis,
)

22. Soft Wrapping

The softWrap property controls whether text should wrap at soft line breaks.

Text(
  'Flutter makes application development easier.',
  softWrap: true,
)

For normal paragraphs, allowing text to wrap is generally appropriate.

23. Text in Containers

Text is frequently placed inside a Container to control its size, padding, background, and border.

Container(
  padding: EdgeInsets.all(16),
  decoration: BoxDecoration(
    color: Colors.blue,
    borderRadius: BorderRadius.circular(12),
  ),
  child: Text(
    'Flutter Text',
    style: TextStyle(
      color: Colors.white,
      fontSize: 20,
      fontWeight: FontWeight.bold,
    ),
  ),
)

24. Text in Cards

Card(
  child: Padding(
    padding: EdgeInsets.all(16),
    child: Column(
      crossAxisAlignment: CrossAxisAlignment.start,
      children: [
        Text(
          'Flutter Course',
          style: TextStyle(
            fontSize: 22,
            fontWeight: FontWeight.bold,
          ),
        ),
        SizedBox(height: 8),
        Text(
          'Learn Flutter from basics to advanced concepts.',
          style: TextStyle(
            fontSize: 16,
            color: Colors.grey,
          ),
        ),
      ],
    ),
  ),
)

25. TextTheme

For larger applications, defining text styles individually for every Text widget can lead to inconsistent typography. Flutter's Material system provides TextTheme for organizing commonly used text styles. A theme's text theme can be accessed through Theme.of(context).textTheme. :contentReference[oaicite:7]{index=7}

Example

Text(
  'Dashboard',
  style: Theme.of(context).textTheme.headlineMedium,
)

26. Common TextTheme Styles

The exact available styles depend on the Flutter Material API and theme configuration, but commonly used Material text roles include styles such as:

• displayLarge
• displayMedium
• displaySmall
• headlineLarge
• headlineMedium
• headlineSmall
• titleLarge
• titleMedium
• titleSmall
• bodyLarge
• bodyMedium
• bodySmall
• labelLarge
• labelMedium
• labelSmall

Example

Column(
  crossAxisAlignment: CrossAxisAlignment.start,
  children: [
    Text(
      'Main Heading',
      style: Theme.of(context).textTheme.headlineMedium,
    ),
    Text(
      'Section Title',
      style: Theme.of(context).textTheme.titleLarge,
    ),
    Text(
      'Body content goes here.',
      style: Theme.of(context).textTheme.bodyMedium,
    ),
  ],
)

27. Defining a Global Text Theme

A global text theme can be defined through ThemeData. This allows common typography choices to be shared across the application.

MaterialApp(
  theme: ThemeData(
    textTheme: const TextTheme(
      headlineLarge: TextStyle(
        fontSize: 32,
        fontWeight: FontWeight.bold,
      ),
      titleLarge: TextStyle(
        fontSize: 22,
        fontWeight: FontWeight.w600,
      ),
      bodyLarge: TextStyle(
        fontSize: 18,
      ),
      bodyMedium: TextStyle(
        fontSize: 16,
      ),
    ),
  ),
  home: const HomeScreen(),
)

28. Using Theme Styles in Widgets

class HomeScreen extends StatelessWidget {
  const HomeScreen({super.key});

  @override
  Widget build(BuildContext context) {
    final textTheme = Theme.of(context).textTheme;

    return Scaffold(
      appBar: AppBar(
        title: const Text('Typography'),
      ),
      body: Padding(
        padding: const EdgeInsets.all(20),
        child: Column(
          crossAxisAlignment: CrossAxisAlignment.start,
          children: [
            Text(
              'Welcome',
              style: textTheme.headlineMedium,
            ),
            const SizedBox(height: 10),
            Text(
              'This application uses a shared text theme.',
              style: textTheme.bodyLarge,
            ),
          ],
        ),
      ),
    );
  }
}

29. DefaultTextStyle

DefaultTextStyle provides a default text style to descendant Text widgets that do not specify their own explicit style. :contentReference[oaicite:8]{index=8}

DefaultTextStyle(
  style: TextStyle(
    fontSize: 18,
    color: Colors.blue,
  ),
  child: Column(
    children: [
      Text('First Text'),
      Text('Second Text'),
      Text('Third Text'),
    ],
  ),
)

This is useful when multiple text widgets inside the same section should share a common style.

30. TextStyle Inheritance

By default, a TextStyle can inherit unspecified values from the surrounding text style. For example, you can change only the font weight while allowing other inherited values to remain unchanged. :contentReference[oaicite:9]{index=9}

DefaultTextStyle(
  style: TextStyle(
    fontSize: 18,
    color: Colors.blue,
  ),
  child: Text(
    'Bold Blue Text',
    style: TextStyle(
      fontWeight: FontWeight.bold,
    ),
  ),
)

31. RichText

When different parts of a single piece of text need different styles, RichText and TextSpan can be used. This is useful for highlighting words, creating mixed styles, or displaying formatted text.

RichText(
  text: TextSpan(
    text: 'Welcome to ',
    style: TextStyle(
      fontSize: 20,
      color: Colors.black,
    ),
    children: [
      TextSpan(
        text: 'Flutter',
        style: TextStyle(
          fontWeight: FontWeight.bold,
          color: Colors.blue,
        ),
      ),
      TextSpan(
        text: ' Development',
        style: TextStyle(
          color: Colors.black,
        ),
      ),
    ],
  ),
)

32. TextSpan

TextSpan represents a span of text that can have its own style. Multiple TextSpan objects can be combined inside a RichText widget.

RichText(
  text: TextSpan(
    children: [
      TextSpan(
        text: 'Price: ',
        style: TextStyle(
          color: Colors.black,
        ),
      ),
      TextSpan(
        text: '₹999',
        style: TextStyle(
          color: Colors.green,
          fontWeight: FontWeight.bold,
        ),
      ),
    ],
  ),
)

33. Text with Gesture Interaction

TextSpan can also be combined with a TapGestureRecognizer to create interactive portions of rich text.

import 'package:flutter/gestures.dart';
import 'package:flutter/material.dart';

RichText(
  text: TextSpan(
    text: 'Read our ',
    style: const TextStyle(
      color: Colors.black,
    ),
    children: [
      TextSpan(
        text: 'Terms and Conditions',
        style: const TextStyle(
          color: Colors.blue,
          decoration: TextDecoration.underline,
        ),
        recognizer: TapGestureRecognizer()
          ..onTap = () {
            print('Terms clicked');
          },
      ),
    ],
  ),
)

34. Selectable Text

When users need to copy text from the application, Flutter provides selectable text widgets such as SelectableText.

SelectableText(
  'This text can be selected and copied.',
  style: TextStyle(
    fontSize: 18,
  ),
)

35. Text with Icons

Text and icons are frequently combined using Row.

Row(
  children: [
    Icon(
      Icons.email,
      color: Colors.blue,
    ),
    SizedBox(width: 8),
    Text(
      '[email protected]',
      style: TextStyle(
        fontSize: 16,
      ),
    ),
  ],
)

36. Text in Buttons

ElevatedButton(
  onPressed: () {},
  child: Text(
    'Login',
    style: TextStyle(
      fontSize: 18,
      fontWeight: FontWeight.bold,
    ),
  ),
)

For larger applications, button typography can also be managed through the application's theme and button styles.

37. Text Overflow in Row

A common layout problem occurs when long text is placed inside a Row. Expanded or Flexible can be used to give the text a constrained amount of space.

Row(
  children: [
    Icon(Icons.person),
    SizedBox(width: 10),
    Expanded(
      child: Text(
        'This is a very long username that may not fit.',
        maxLines: 1,
        overflow: TextOverflow.ellipsis,
      ),
    ),
  ],
)

38. Responsive Typography

Typography should remain readable on different screen sizes. Avoid relying on unnecessarily large fixed text sizes. Use appropriate theme styles, constraints, and layouts.

Example

LayoutBuilder(
  builder: (context, constraints) {
    final size = constraints.maxWidth < 600 ? 24.0 : 32.0;

    return Text(
      'Responsive Heading',
      style: TextStyle(
        fontSize: size,
        fontWeight: FontWeight.bold,
      ),
    );
  },
)

39. Text Scaling

Flutter provides text scaling support so that text can adapt to accessibility and platform settings. The modern Text API uses TextScaler; the older textScaleFactor property is deprecated in current Flutter documentation. :contentReference[oaicite:10]{index=10}

Text(
  'Accessible Flutter Text',
  textScaler: TextScaler.linear(1.2),
)

In production applications, avoid unnecessarily overriding user text-scaling preferences unless there is a specific design requirement.

40. Typography for a Login Screen

Column(
  crossAxisAlignment: CrossAxisAlignment.start,
  children: [
    Text(
      'Welcome Back',
      style: TextStyle(
        fontSize: 30,
        fontWeight: FontWeight.bold,
      ),
    ),
    SizedBox(height: 8),
    Text(
      'Login to continue to your account.',
      style: TextStyle(
        fontSize: 16,
        color: Colors.grey,
        height: 1.5,
      ),
    ),
    SizedBox(height: 25),
    Text(
      'Email',
      style: TextStyle(
        fontSize: 16,
        fontWeight: FontWeight.w600,
      ),
    ),
  ],
)

41. Typography for a Product Card

Card(
  child: Padding(
    padding: EdgeInsets.all(16),
    child: Column(
      crossAxisAlignment: CrossAxisAlignment.start,
      children: [
        Text(
          'Flutter Laptop',
          style: TextStyle(
            fontSize: 20,
            fontWeight: FontWeight.bold,
          ),
        ),
        SizedBox(height: 6),
        Text(
          'High-performance laptop for development.',
          style: TextStyle(
            fontSize: 14,
            color: Colors.grey,
            height: 1.4,
          ),
        ),
        SizedBox(height: 12),
        Text(
          '₹75,000',
          style: TextStyle(
            fontSize: 22,
            fontWeight: FontWeight.bold,
            color: Colors.green,
          ),
        ),
      ],
    ),
  ),
)

42. Typography Hierarchy

A good typography hierarchy helps users understand which information is most important.

43. Good Typography Practices

• Use a consistent font family throughout the application.
• Use a clear hierarchy between headings, titles, body text, and labels.
• Avoid using too many different font families.
• Use appropriate font weights instead of making every heading bold.
• Use sufficient line height for paragraphs.
• Use text colors that provide adequate contrast.
• Handle long text using maxLines and TextOverflow where appropriate.
• Use responsive layouts so text does not overflow on smaller screens.
• Prefer theme-based typography for consistency across screens.
• Respect accessibility and user text-scaling settings.

44. Common Mistakes in Flutter Typography

Mistake 1: Using Excessive Font Sizes

Text(
  'Welcome',
  style: TextStyle(
    fontSize: 80,
  ),
)

Very large text can cause overflow and poor layout on smaller devices.

Mistake 2: Ignoring Text Overflow

Row(
  children: [
    Icon(Icons.info),
    Text('A very long text that may overflow'),
  ],
)

Use Expanded or Flexible when the text needs to share limited horizontal space.

Mistake 3: Repeating the Same TextStyle Everywhere

Instead of manually repeating the same styles, use TextTheme and application-level themes.

Mistake 4: Poor Line Height

Very small line spacing can make paragraphs difficult to read. Use the height property when appropriate.

Mistake 5: Too Many Font Styles

Using many font families, colors, sizes, and decorations can make an application visually inconsistent.

45. Complete Typography Example

import 'package:flutter/material.dart';

void main() {
  runApp(const TypographyApp());
}

class TypographyApp extends StatelessWidget {
  const TypographyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      theme: ThemeData(
        colorScheme: ColorScheme.fromSeed(
          seedColor: Colors.blue,
        ),
        textTheme: const TextTheme(
          headlineLarge: TextStyle(
            fontSize: 32,
            fontWeight: FontWeight.bold,
          ),
          titleLarge: TextStyle(
            fontSize: 22,
            fontWeight: FontWeight.w600,
          ),
