Use other plugins in callback

Use other plugins in callback

By Marcelo Henrique Neppel.

The idea is to register the plugins manually.

1. Create Application file for your android project

class Application : FlutterApplication(), PluginRegistrantCallback {
    override fun onCreate() {
        super.onCreate()
        LocatorService.setPluginRegistrant(this)
        FlutterMain.startInitialization(this)
    }
    
    override fun registerWith(registry: PluginRegistry?) {
        if (!registry!!.hasPlugin("io.flutter.plugins.pathprovider")) {
            PathProviderPlugin.registerWith(registry!!.registrarFor("io.flutter.plugins.pathprovider"))
        }
    }
}

2. Register your Application class in manifest

<application
        android:name=".Application"

3. Now you can use this plugin in you main dart code:

static void callback(LocationDto locationDto) async {
  print('location in dart: ${locationDto.toString()}');
  final SendPort send = IsolateNameServer.lookupPortByName(_isolateName);
  send?.send(locationDto);
  //the '?' check if send is null before executing it

  final file = await _getTempLogFile();
  await file.writeAsString(locationDto.toString(), mode: FileMode.append);
}
