dalipush 0.0.1

一款集成了阿里推送的flutter插件，使用起来不是很简单，需要在你flutter的android项目中配置一个自己的application，并且在android app的gradle文件中做几个占位符，具体可以看reade.me

import 'package:flutter/material.dart';
import 'dart:async';

import 'package:flutter/services.dart';

void main() => runApp(new MyApp());

//  StreamSubscription<dynamic> _messageStreamSubscription;

  @override
  void initState() {
    super.initState();
    initPlatformState();
  }

  // Platform messages are asynchronous, so we initialize in an async method.
  Future<void> initPlatformState() async {
    String platformVersion;
    // Platform messages may fail, so we use a try/catch PlatformException.
    try {
      platformVersion = await Dalipush().platformVersion;
    } on PlatformException {
      platformVersion = 'Failed to get platform version.';
    }

    // If the widget was removed from the tree while the asynchronous platform
    // message was in flight, we want to discard the reply rather than calling
    // setState to update our non-existent appearance.
    if (!mounted) return;

//    if (_messageStreamSubscription == null) {
//      _messageStreamSubscription = _push.onMessage.listen((dynamic onData) {
//        print("我收到了推送$onData");
