Future Loading Dialog

Easy to use adaptive loading dialog to visualize a Dart Future.

Displays a loading dialog which reacts to the given future. The dialog will be dismissed and the value will be returned when the future completes. If an error occured, then onError will be called and this method returns null. Set title and backLabel to controll the look and feel or set LoadingDialog.defaultTitle, LoadingDialog.defaultBackLabel and LoadingDialog.defaultOnError to have global preferences.


Will display a loading dialog for one second.

  title: 'Test',
  home: Scaffold(
    body: Builder(
      builder: (context) => RaisedButton(
        child: Text('Test'),
        onPressed: () => showFutureLoadingDialog(
          context: context,
          future: () => Future.delayed(Duration(seconds: 1)),
