Write A Dart Program In Assert Keyword
In Dart, assert keyword is a powerful tool useful for catching errors and inconsistencies during development, but doesn't affect the program's execution in production mode. It checks if a given condition is true, and if not, throws an AssertionError with a custom message. This is especially valuable for verifying assumptions about program state, validating input, or detecting edge cases. When an assertion fails, the program will halt with a detailed error message, aiding in debugging and reducing the likelihood of hard-to-troubleshoot errors in production.

Course Overview
This course provides an introduction to using the assert keyword in Dart programming. It covers the basics of assertions, including their purpose, syntax, and usage. Additionally, the course explores advanced topics such as conditional assertions and the use of custom error messages. Through practical examples and exercises, students will gain a thorough understanding of how to effectively utilize assertions to improve the reliability and maintainability of their Dart code.
Course Description
This course will teach you how to use the assert keyword in Dart to check the validity of your code and to verify that certain conditions are met at runtime. The assert keyword allows you to specify a condition that should be true at the time the code is executed, and if the condition is not met, an AssertionError exception will be thrown. You will learn how to use the assert keyword to check for null values, to verify that a value is within a certain range, and to ensure that certain assumptions about the state of your program are met.
