    LocationData location = await new Location().getLocation();
    print(location.latitude.toString() + " " + location.longitude.toString());
  }
}

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  final isolate = await FlutterIsolate.spawn(isolate1, "hello");
  LocationData location = await new Location().getLocation();

Your problem is with this

Please see here and here for why.

Also please use code formatting in your issue to make it readable

[mohpezeshki]

but i can not run even your example because this Unhandled Exception: MissingPluginException error i use stable channel and flutter version v1.9.1+hotfix.2

@rmawatson same error with my own custom channel, works fine in the main isolate.

P.S. Native code doesn't even get called, tested on android

[rmawatson]

without looking at it I'm not sure. You can try applying this PR https://github.com/rmawatson/flutter_isolate/pull/22

[VadimOsovsky]

@rmawatson applying the PR did not help to solve the issue, can you please check if custom platformChannel calls work with this lib?
