What does 'widget is disposed' mean for state management?

If a widget is disposed of, any state it holds is no longer accessible. This is particularly important when using state management solutions like Provider, BLoC, or Riverpod. If you're relying on a widget to hold state, and that widget is disposed of, your application will likely experience unexpected behavior because the state is gone. You need to ensure your state management solution is properly handling the disposal of widgets to prevent data loss or inconsistencies.
