Have you had experience working with the concept of Never in your projects or practical tasks?

In the Dart language (used in Flutter), the Never type indicates a type that never returns a value. This means that a function with a return type of Never either runs infinitely, throws an exception, or terminates the program.

Example of usage:

Never throwError(String message) {
  throw Exception(message);
}

void main() {
  throwError("Error");
  // Code below is unreachable
}

In projects, Never helps explicitly indicate that a function will not complete normally, which improves code analysis and prevents errors.

If you have experience handling errors, creating functions that terminate execution, or infinite loops, you have likely encountered Never.
