build method

@override Widget build()

Subclasses should override this function to actually call the appropriate build function (e.g., StatelessWidget.build or State.build) for their widget.

Implementation

@override
Widget build() {
  if (_instanceOrStatesDirty.isNotEmpty) {
    notifyClients(widget);

    return _widget!;
  }

  if (parent != null) {
    return _widget = widget._buildWithChild(parent?.injectedChild);
  }

  return _widget = widget.build(this);
}
