kjelly / easy_isolate

The wrapper for the isolate.

EasyIsolate

The library provide a wrapper to use the isolate more easily.

Usecase

Call one, get one

Run the anonymous function in the another isolate. When the anonymous function finished, the isolate end.

import 'package:easy_isolate/easy_isolate.dart';
Future<void> main() async {
  var o = await EasyIsolate.run((args) {return args[0];}, [1, 2]);
  // o will be 1.
}

Call one, get one, multiple isolates

Create multiple isolates to wait for request. Send the request by calling the call method. If no more request, call the close method to end the isolates. The isolates will be alive till the close method is called.

import 'package:easy_isolate/easy_isolate.dart';
Future<void> main() async {
  EasyIsolate actor1 = EasyIsolate((args) {
    return args + args;
  }, worker: 2);
  await actor.call(["bye"]);
  await actor.close();
}

Call one, get stream, multiple isolates

Create the stream in the another isolate. When the stream end, The isolate end.

import 'package:easy_isolate/easy_isolate.dart';
Future<void> main() async {
  EasyIsolate.createStream((args) {
    return testStream();
  }).listen((data) {
    print('stream: $data');
  });
}
Stream testStream() async* {
  var index = 0;
  while (index < 5) {
    yield index++;
  }
}
