@pragma('vm:entry-point') void callbackDispatcher() { Workmanager().executeTask((taskName, inputData) { print('Inside WorkManager execute'); return Future.value(true); }); }

void main() { runApp(const MyApp()); }

class MyApp extends StatefulWidget { const MyApp({Key? key}) : super(key: key);

@override State<MyApp> createState() => _MyAppState(); }

class _MyAppState extends State<MyApp> { @override Widget build(BuildContext context) { return MaterialApp( debugShowCheckedModeBanner: false, theme: ThemeData( primarySwatch: Colors.blue, ), home: const MyHomePage(), ); } }

@override State<MyHomePage> createState() => _MyHomePageState(); }

class _MyHomePageState extends State<MyHomePage> { @override void initState() { initWorkManager(); super.initState(); }

void initWorkManager() async { try { print('iniside try,,,,,,,,,,,catch workmanager block'); Workmanager() .initialize(callbackDispatcher, isInDebugMode: true) .then((_) async { await Workmanager().registerPeriodicTask( simplePeriodicTask, simplePeriodicTask, initialDelay: Duration(seconds: 10), ); }); } catch (e) { print('Exception in register work manager'); } }

@override Widget build(BuildContext context) { return Scaffold( appBar: AppBar( centerTitle: true, title: const Text("Work manager Example"), ), body: Center( child: Column( mainAxisAlignment: MainAxisAlignment.center, children: <Widget>[], ), ), ); } } `

The Target platform is not specified, but in the case of iOS, It's not a bug but expected behavior.

When an app is explicitly terminated by the user or the system, iOS will stop all background tasks for this process. This is by design.

me too. not working only on android case when terminated app flutter version 3.3.1

update After updating flutter to 3.7.12 it works. If using the emulater after installing the app for the first time. app must be opened and terminated 1 time. after that it will work even after restarting the device. If using a real device, there is no problem.

Any updates on this? I am using Channel stable, 3.19.2, on macOS 13.6.4 22G513 darwin-arm64

My worker triggers when I turn on the Internet. This works well when the app is in Foreground or Background. But, when the app is either closed or terminated, and I turn on the Internet, I see the Debug notification from my Worker. But is executed only when I attempt to open the app. Right when I open the app, the Work executes and Is successful.
