android - Are Flutter Isolates enough to keep some parts of the app working in the background?

Question

I had some issues with web-sockets disconnecting when the app is in the background and the need to frequently send location data from the device even if it's backgrounded. Based on some researching I found the flutter team praising a way to make background process work using native code for both platforms IOS and Android. But surely there has to be a way to make it work with just Dart. So I tried Isolates as shown below:

import 'dart:async';
import 'dart:isolate';

import 'package:driver_app/home.dart';
import 'package:flutter/material.dart';

void callBack(SendPort sendPort) {
  Timer.periodic(
    Duration(seconds: 1),
    (timer) {
      sendPort.send(timer.tick);
    },
  );
}

void main() async {
  WidgetsFlutterBinding.ensureInitialized();

  ReceivePort _receivePort = ReceivePort();
  await Isolate.spawn(callBack, _receivePort.sendPort);
  _receivePort.listen((message) {
    print("New Message: ($message)");
  });

  runApp(Home());
}

I still can't confirm if this is a good practice for my intentions if not the best, may you confirm if it's correct?
