Android工程集成flutter

官方方案

github.com/flutter/flu…

第一个步：新建一个标准的APP工程testFlutterInAPP，APP目录下面通过命令创建flutter模块工程

flutter create -t module my_flutter

编译flutter 代码生成Android的AAR文件

$ cd .android/$ ./gradlew flutter:assembleDebug复制代码

AAR 文件生成到.android/Flutter/build/outputs/aar/目录下面

添加Host APP 依赖flutter module 模块，在setting.gradle 文件中加入

include ':app'                                     // assumed existing contentsetBinding(new Binding([gradle: this]))                                 // newevaluate(new File(                                                      // new  settingsDir.parentFile,                                               // new  'my_flutter/.android/include_flutter.groovy'                          // new)) 复制代码

app/build.gradle 增加对flutter 工程依赖

// testFlutterInAPP/app/build.gradledependencies {  implementation project(':flutter')}复制代码

构建成功后，执行Android的run启动应用 ,点击打开flutter 。

Java 层代码

 openFlutter.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View view) {                View flutterView = Flutter.createView(                        MainActivity.this,                        getLifecycle(),                        "route1"                );                FrameLayout.LayoutParams layout = new FrameLayout.LayoutParams(600, 800);                layout.leftMargin = 100;                layout.topMargin = 200;                addContentView(flutterView, layout);            }        });复制代码

flutter 代码

import 'dart:ui';import 'package:flutter/material.dart';void main() => runApp(_widgetForRoute(window.defaultRouteName));Widget _widgetForRoute(String route) {  switch (route) {    case 'route1':      return new MyApp();    case 'route2':      return new MyApp();    default:      return Center(        child: Text('Unknown    route1 : $route', textDirection: TextDirection.ltr),      );  }  return new MyApp();}class MyApp extends StatelessWidget {  // This widget is the root of your application.  @override  Widget build(BuildContext context) {    return new MaterialApp(      title: 'Flutter Demo',      theme: new ThemeData(        primarySwatch: Colors.blue,      ),      home: new MyHomePage(title: 'Flutter Demo 1111'          'Home Page'),    );  }}class MyHomePage extends StatefulWidget {  MyHomePage({Key key, this.title}) : super(key: key);  final String title;  @override  _MyHomePageState createState() => new _MyHomePageState();}class _MyHomePageState extends State {  int _counter = 0;  void _incrementCounter() {    setState(() {           _counter++;    });  }  @override  Widget build(BuildContext context) {    return new Scaffold(      appBar: new AppBar(              title: new Text(widget.title),      ),      body: new Center(                 mainAxisAlignment: MainAxisAlignment.center,          children: [            new Text(              'You have pushed the button this many times:',            ),            new Text(              '$_counter',              style: Theme.of(context).textTheme.display1,            ),          ],        ),      ),      floatingActionButton: new FloatingActionButton(        onPressed: _incrementCounter,        tooltip: 'Increment',        child: new Icon(Icons.add),      ), // This trailing comma makes auto-formatting nicer for build methods.    );  }}复制代码

运行 flutter 工程，进入my_flutter 目录执行flutter run 命令

即可启动flutter ，r == hot reload R == hot restart q == quit d == detach,

或者启动Android应用调试

但是，好像DEBUG无效，等下在验证
