IsolateFlutter provides a way to launch 'dart:isolate' library in Flutter (iOS and Android).

IsolateFlutter #

Pub

IsolateFlutter 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 IsolateFlutter.createAndStart(_testFunction, 'Hello World');
print(_value);

Create and manager an isolate (not run immediately) #

  1. Create an isolate:

     IsolateFlutter _isolateFlutter = await IsolateFlutter.create(_testFunction, 'Hello World');
    
  2. Start and get the value returned by _testFunction

     final _value = await _isolateFlutter.start();
     print(_value);
    
  3. Pause a running isolate

     _isolateFlutter.pause();
    
  4. Resume a paused isolate

     _isolateFlutter.resume();
    
  5. Stop and dispose a an isolate

     _isolateFlutter.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';
  }
