IsolateUtils

IsolateUtils is a useful package for you who want to make and manage Isolate. It is based on dart:isolate so it only support iOS and Android.

It's like compute(): Spawn an isolate, run callback on that isolate, passing it message, and (eventually) return the value returned by callback. But it not top-level constant so you can create multiple Isolates at the same time.

Usage

Create and start an isolate

final _value = await IsolateUtils.createAndStart(_testFunction, 'Hello World');
print(_value);

Create and manager an isolate (not run immediately)

1. Create an isolate:

   IsolateUtils _isolateUtils = await IsolateUtils.create(_testFunction, 'Hello World');
   

2. Start and get the value returned by _testFunction

   final _value = await _isolateUtils.start();
   print(_value);
   

3. Pause a running isolate

   _isolateUtils.pause();
   

4. Resume a paused isolate

   _isolateUtils.resume();
   

5. Stop and dispose a an isolate

   _isolateUtils.stop();
   

Example test function

static Future<String> _testFunction(String message) async {
    Timer.periodic(Duration(seconds: 1), (timer) => print('$message - ${timer.tick}'));
    await Future.delayed(Duration(seconds: 30));
    return '_testFunction finish';
  }
