How to use Hive with Workmanger?

[shinewanna]

Steps to Reproduce When update or add in Hive db with Workmanger, there's no change on db.

Code sample

callbackDispatcher() {
  Workmanager.executeTask((task, inputData) async {
    MessageOb messageOb;
    try {
      messageOb = MessageOb.fromJson(inputData);
      await SmsHandler.sendMessage(messageOb);
    } catch (e) {
      print("Error Sending");
    }
    messageOb.messageStatusIndex = 1;
    // final appDocDir = await getApplicationDocumentsDirectory();

    // Hive.init(appDocDir.path);
    // Hive.registerAdapter(MessageObAdapter(), 0);
    // await Hive.openBox(MESSAGE_BOX);
    await Hive.box(MESSAGE_BOX).(messageOb);
    return Future.value(true);
  });
}

Version

• Platform: Android
• Flutter version: [e.g. 1.20.3]
• Hive version: [e.g. 1.2.0]

This line looks wrong. What is it supposed to do?

await Hive.box(MESSAGE_BOX).(messageOb);

@shinewanna what errors do you have. It should work! if the box is open and registered.

@muarachmann Really??, if the app is not in background, it can't open.

I don't understand your issue given the title... are you talking about working in background mode or with workmanager?

There's already someone asked, answered on other issue. So, i closed this.

use IsolateNameServer for background

final sendPort = IsolateNameServer.lookupPortByName("backgroundtask"); 
 if (sendPort != null) {
          sendPort.send(afterUpdateMessageOb);
 }

on Workmanager.execute and catch the send on your HomePage init like

    IsolateNameServer.registerPortWithName(_port.sendPort, "backgroundtask");
    _port.listen((dynamic data) async {
      MessageOb messageOb = data;
      messageService.updateMessageWithUuid(messageOb.uuid, messageOb);
    });

and for headless service, u can use as i show in question example code, Hive.init(...) and open and do ur stuff.
