No implementation found for method LocatorPlugin.initializeService about background_locator HOT 9 CLOSED

Thanks for your kind response.

Actually while I was working on a sample to show you the code @mehdok I found the issue.

The issue was with my activity, it was extending FlutterActivity but the wrong one

So this was the import of the FlutterActivity:

import io.flutter.app.FlutterActivity

I changed it to the correct one:

import io.flutter.embedding.android.FlutterActivity

Also thanks @harsha-sira for contributing.

@mehdok I just have a question if I'm allowed to ask, is it possible to use another plugin like SharedPreferences while the device's location is updated from the background?

I tried to using this, but causing an error, that the plugin I'm using is not present because the app is terminated.

static void callback(LocationDto locationDto) async {
    print('location in dart: ${locationDto.toString()}');
    print('test long ${locationDto.longitude}, ${locationDto.latitude}');

    SharedPreferences sharedPreferences = await SharedPreferences.getInstance();
    final SendPort send = IsolateNameServer.lookupPortByName(_isolateName);
    send?.send(locationDto);
  }

Do you want me to open another issue for that?

Do you get compile time error or ide error?

Do you get compile time error or ide error?

Sorry for not clarifying the issue, this is the issue I'm getting:

(No implementation found for method LocatorPlugin.initializeService on channel app.rekab/locator_plugin)

I'm getting it in runtime as soon as I call this function:

await BackgroundLocator.initialize();

from background_locator.

Can you make a simple repository with this code? So I can run and see what is happening.

@TahaMalas I also got the same error you got. but then I run the example code as it is and works like a charm. So this should be something wrong with your code.
I'll post again if I found the local issue which I face. it could be the same reason for both of us.

@TahaMalas, Thanks for pointing out the solution. It was the same reason for me as well.

@TahaMalas Glad to see the problem solved. Yes you can use other plugins while app is in background or terminated, follow the steps in Use other plugins in callback and let me know if you have any problem.

@mehdok That's great it worked, thanks for your precious time and valuable package.

Also one last question the app sometimes crashes completely and shows this error from the android logcat not flutter's
Unable to start service rekab.app.background_locator.IsolateHolderService@5e93951 with null: java.lang.IllegalArgumentException: Parameter specified as non-null is null: method kotlin.jvm.internal.Intrinsics.checkParameterIsNotNull, parameter intent

Any ideas?
