Dart Keywords

Dart, like any programming language, has a set of keywords that serve as reserved words with special meanings in the language. Here are some of the Dart keywords:

abstract: Used to declare an abstract class or to indicate that a method does not have a body and must be implemented in a subclass.
as: Used in import statements to specify a prefix for a library.
assert: Used to throw an exception if a given Boolean expression is false. It's often used for debugging purposes.
async: Used to declare an asynchronous function. Functions marked with async can use the await keyword to pause execution until a Future is complete.
await: Used within an async function to pause execution until the awaited Future completes.
break: Used to exit a loop prematurely.
case: Used in a switch statement to define different cases.
catch: Used to catch exceptions in a try-catch block.
class: Used to declare a class.
const: Used to define a compile-time constant.
continue: Used to skip the rest of a loop's body and move to the next iteration.
covariant: Used in method parameters to allow a subclass to override a method with a parameter type different from the one in the superclass.
default: Used in a switch statement to provide a default case.
deferred: Used in import statements to load a library lazily.
do: Used to start a do-while loop.
dynamic: Represents a dynamic type. Variables of type dynamic can hold values of any type.
else: Used in an if-else statement.
enum: Used to declare an enumeration, a special kind of class representing a fixed number of constant values.
export: Used to export symbols from one Dart library to another.
extends: Used in a class declaration to indicate the class being extended.
extension: Used to declare an extension, allowing you to add new functionality to existing types.
external: Indicates that a member is implemented in external code, such as JavaScript.
factory: Used in a class to indicate that a constructor returns an instance of the class.
false: Boolean literal representing the false value.
final: Used to declare a variable that cannot be reassigned.

These are just some of the keywords in Dart. Understanding and using these keywords correctly is essential for effective Dart programming.
