Describe the error
Hello, community. I am registering a periodic task with the work manager package. I have tried calling the method channel with the following code:

void callbackDispatcher() {
  Workmanager().executeTask((task, inputData) async {
    print("======================================== WorkManager");
    await logToFile("======================================== WorkManager");

    WidgetsFlutterBinding.ensureInitialized();

    print("WorkManager : Task started: $task");
    await logToFile("WorkManager : Task started: $task");

    print("WorkManager : Input data: $inputData");
    await logToFile("WorkManager : Input data: $inputData");

 try {
      if (task == taskMidnightAPI) {
          static const MethodChannel _channel = MethodChannel('mypackage/custom_notifications');
           final res = await _channel.invokeMethod('scheduleDailyAlarm', {
            'id': id,
            'hour': hour,
            'minute': minute,
          });
      }
   } catch (e, stackTrace) {
      log(e.toString(), error: e, stackTrace: stackTrace, name: "WORK MANAGER(CALL BACK ERROR)");
    } 
}

But I am getting following error:

MissingPluginException(No implementation found for method scheduleDailyAlarm on channel mypackage/custom_notifications)
