                    child: Text("isscheduled (Android)"),
                    onPressed: Platform.isAndroid
                        ? () async {
                            final workInfo =
                                await Workmanager().isScheduledByUniqueName(
                              simplePeriodicTask,
                            );
                            print('isscheduled = $workInfo');
                          }
                        : null),
                SizedBox(height: 8),

I have added a dependency workmanager in my projects pubspec.yaml file and also imported a package import 'package:workmanager/workmanager.dart';

Answer 1

bro i think this method Workmanager().isScheduledByUniqueName() is not define in Workmanager class.you can schedule task by this 2 methods.

1. registerOneOffTask : for one time task
2. registerPeriodicTask : for run task at specified interval.
