How do I run async work on text field changes but only after some seconds when the user is done changing the field?

I have a field in a form that takes in a username. When this value changes, some asynchronous work runs. Right now the asynchronous work is firing on every letter change. How do I make it so that it only fires some amount of seconds after the user has changed the field and when the user isn’t making any more changes?

TextField(
    controller: userController,
    onChanged: (text) {
      asyncWorkThatDoesntNeedToBeAwaited(text);
    },
),

>Solution :

There is a package name easy_debounce.

Here is an example of it in use – repo
