Progress Builder #

A simple wrapper for asynchronous actions with progress/loading indications and error handling.

Usage #

The following will: - await the Future.delayed() - show LinearProgressIndicator while it is being awaited - print 'success' if successful - print error: ...exception... in case of an exception - print 'done' in all cases

import 'package:progress_builder/progress_builder.dart';

...
                LinearProgressBuilder(
                  builder: (action, _) => ElevatedButton(
                    onPressed: action,
                    child: Text('PRESS ME'),
                  ),
                  action: () async {
                    print('loading');
                    await Future.delayed(const Duration(seconds: 2));
                    print('loaded');
                  },
                  onDone: () => print('done'),
                  onError: (error) => print('error $error'),
                  onSuccess: () => print('success'),
                ),
