Android工程集成flutter

官方方案

https://github.com/flutter/flutter/wiki/Add-Flutter-to-existing-apps

第一個步：
新建一個標準的APP工程testFlutterInAPP，APP目錄下面通過命令創建flutter模塊工程

flutter create -t module my_flutter

編譯flutter 代碼生成Android的AAR文件

$ cd .android/ $ ./gradlew flutter:assembleDebug 

AAR 文件生成到.android/Flutter/build/outputs/aar/目錄下面

添加Host APP 依賴flutter module 模塊，在setting.gradle 文件中加入

include ':app' // assumed existing content setBinding(new Binding([gradle: this])) // new evaluate(new File(// new settingsDir.parentFile, // new 'my_flutter/.android/include_flutter.groovy'// new ))

app/build.gradle 增加對flutter 工程依賴

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

構建成功后，執行Android的run啟動應用 ,點擊打開flutter 。

Java 層代碼

 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); } }); 

flutter 代碼

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('Unknownroute1 : $route', textDirection: TextDirection.ltr), ); } return new MyApp(); } class MyApp extends StatelessWidget { // This widget is the root of your application. @override Widget build(BuildContext context) { return new MaterialApp( title: 'Flutter Demo', theme: new ThemeData( primarySwatch: Colors.blue, ), home: new MyHomePage(title: 'Flutter Demo 1111' 'Home Page'), ); } }class MyHomePage extends StatefulWidget { MyHomePage({Key key, this.title}) : super(key: key);final String title;@override _MyHomePageState createState() => new _MyHomePageState(); }class _MyHomePageState extends State<MyHomePage> { int _counter = 0;void _incrementCounter() { setState(() {_counter++; }); }@override Widget build(BuildContext context) { return new Scaffold( appBar: new AppBar(title: new Text(widget.title), ), body: new Center( mainAxisAlignment: MainAxisAlignment.center, children: <Widget>[ new Text( 'You have pushed the button this many times:', ), new Text( '$_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. ); } } 

運行 flutter 工程 ，進入my_flutter 目錄執行flutter run 命令

即可啟動flutter ，r == hot reload R == hot restart
q == quit d == detach,

或者啟動Android應用調試

但是，好像DEBUG無效？？
