build method
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 (_dirty) {
notifyClients(widget);
}
// return Notifier.instance.notifyAppend(
// NotifyData(
// disposers: disposers, updater: getUpdate, throwException: false),
return super.build();
//);
}
