Debounce

Debouncing ensures that the function is only called once after a specified duration has passed since the last time it was invoked. This is useful for scenarios where you want to limit the rate at which a function is executed, such as handling user input events or API calls.

final debouncer = Debounce(()=> print('Hello, world!'), duration: Duration(seconds: 1));
