dispose method

@mustCallSuper void dispose()

The framework calls this method when this StateX object will never build again. Note: YOU WILL HAVE NO IDEA WHEN THIS WILL RUN in the Framework.

Implementation

@mustCallSuper
void dispose() {
  /// The framework calls this method when this [StateX] object will never
  /// build again. The [State] object's lifecycle is terminated.
  /// Subclasses should override this method to release any resources retained
  /// by this object (e.g., stop any active animations).
  // Clear its ChangeNotifier
  _disposeChangeNotifier();

  /// Clean up memory
  disposeSetState();

  // App State object
  _appStateX = null;

  // If instantiated in a factory constructor
  // Note: You don't know when this function will fire!
  // _initStateCalled = false;

  // Optionally call super for debugPrint()
  assert(() {
    if (_debugPrintEvents) {
      debugPrint('$_consoleLeadingLine dispose() in $_consoleClassName');
    }
    return true;
  }());
}
