This example creates a TextField with a TextEditingController whose change listener forces the entered text to be lower case and keeps the cursor at the end of the input.

Final myController = TextEditingController(); @override void dispose() { // Clean up the controller when the widget is removed from the // widget tree. myController. dispose(); super. dispose(); } @override Widget build(BuildContext context) { // Fill this out in the next step. } }

What Does Dispose Mean? In the context of C#, dispose is an object method invoked to execute code required for memory cleanup and release and reset unmanaged resources, such as file handles and database connections.The Dispose method, provided by the IDisposable interface, implements Dispose calls.

The Dispose() method The Dispose method performs all object cleanup, so the garbage collector no longer needs to call the objects' Object.Therefore, the call to the SuppressFinalize method prevents the garbage collector from running the finalizer.

Dispose() will not be called automatically. If there is a finalizer it will be called automatically. Implementing IDisposable provides a way for users of your class to release resources early, instead of waiting for the garbage collector.
