wuchuheng_isolate_channel

This a library to simplify isolate thread communication. It abstracts the data transfer between isolate and the main thread into a simple channel, and the channel only needs to listen for data changes and close the channel, thus simplifying the data communication of islate.

Features

• channel abstraction.
• Data Listening.
• Message Channel Close event.

Getting started

Depend on it Run this command: With Dart:

With Flutter:

$ flutter pub add wuchuheng_isolate_channel

import 'package:wuchuheng_isolate_channel/src/service/task/index.dart';
import 'package:wuchuheng_isolate_channel/wuchuheng_isolate_channel.dart';

void main() async {
    /// Isolate logic code.
    final Task task = await IsolateTask((message, channel) async {
        print("isolate: receive $message");
        channel.send('task data');
        channel.onClose((name) => print('Channel is closed. channel: $name.'));
    });

    ///Main thread code.
    final channel = task.createChannel(name: 'channelName')
        ..listen((message, channel) async => print('Receiving isolate messages')).cancel();
    channel.send('Send data to isolate');
    await Future.delayed(Duration(seconds: 1));

    ///Turn off the channel
    channel.close();

    /// listen to future
    final task2 = await IsolateTask((message, channel) async {
        print(message); //  print: Are you OK? Isolate task
        channel.send('Nice!');
    });
    final channel2 = task2.createChannel();
