onDispose method

@override @protected void onDispose()

Called when the node is being disposed.

Override to provide custom cleanup logic. Called automatically by dispose.

Example:

class MyNode<T> with DisposableNodeMixin implements DisposableNode {
  @override
  void onDispose() {
    // Clean up resources
  }
}

Implementation

@override
@protected
void onDispose() {
  // Mark as scheduled so schedule() returns early and no new frame callback
  // is queued. Any pending callback will see isDisposed and skip execution.
  _isScheduled = true;
  doCleanup();
  disposeNode(this);
}
