Description:

future loading dialog

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.
Example: #
Will display a loading dialog for one second.
MaterialApp(
title: 'Test',
home: Scaffold(
body: Builder(
builder: (context) => RaisedButton(
child: Text('Test'),
onPressed: () => showFutureLoadingDialog(
context: context,
future: () => Future.delayed(Duration(seconds: 1)),
),
),
),
),
);
