    renderLoad: () => new CircularProgressIndicator(),
    renderError: ([error]) =>
        new Text('Sorry, there was an error loading your joke'),
    renderSuccess: ({data}) => new Text(data),
);

Trigger reload #

class ExampleApp extends StatelessWidget {
  final GlobalKey<AsyncLoaderState> _asyncLoaderState =
      new GlobalKey<AsyncLoaderState>();

  reload() {

}

class ExampleApp extends StatelessWidget {
  final GlobalKey<AsyncLoaderState> _asyncLoaderState =
      new GlobalKey<AsyncLoaderState>();

  @override
  Widget build(BuildContext context) {
    var _asyncLoader = new AsyncLoader(
      key: _asyncLoaderState,
      initState: () async => await getMessage(),
      renderLoad: () => new CircularProgressIndicator(),
      renderError: ([error]) =>
          new Text('Sorry, there was an error loading your joke'),

          floatingActionButton: new FloatingActionButton(
            onPressed: () => _asyncLoaderState.currentState
                .reloadState()
                .whenComplete(() => print('finished reload')),
