- 新建Android项目
- 新建Flutter Module(可以在Android项目外任意目录)
- Android项目关联FlutterModule
在Android项目settings.gradle中添加:
setBinding(new Binding([gradle: this])) evaluate(new File('../flutter_module/.android/include_flutter.groovy')) 如果FlutterModule与Android项目不在同一目录下，可以写FlutterModule的绝对地址。
编译之后会在Android项目中生成flutter Module,与正常Android Module类似。 在Android项目App目录下的build.gradle中添加依赖：
dependencies { ... implementation project(':flutter') } - 在FlutterModule中添加FlutterBoost依赖：
flutter_boost: git: url: 'https://github.com/alibaba/flutter_boost.git' ref: 'v1.17.1-hotfixes' pub get之后在Android项目中会生成flutter_boost Module
- 在Android项目中依赖
flutter_boost:
dependencies { ... implementation project(':flutter') implementation project(':flutter_boost') } - 在Android项目中初始化FlutterBoost
//在Application中初始化 fun init(app: Application) { val platform: Platform = FlutterBoost.ConfigBuilder(app, router) .isDebug(true) .whenEngineStart(FlutterBoost.ConfigBuilder.ANY_ACTIVITY_CREATED) .renderMode(FlutterView.RenderMode.texture) .build() FlutterBoost.instance().init(platform) } private val router = INativeRouter { context, url, urlParams, requestCode, exts -> val params = urlParams ?: mutableMapOf() exts?.let { params.putAll(it) } //原生Scheme协议可以自定义 if (url.startsWith("native://")) { //跳转原生页面 //原生页面用Scheme的方式跳转，需要在AndroidManifest中为目标页面注册Scheme val intent = Intent(Intent.ACTION_VIEW) val serializableMap = BoostFlutterActivity.SerializableMap() serializableMap.map = params intent.putExtra("params", serializableMap) intent.data = Uri.parse(url) if (context is Activity) { context.startActivityForResult(intent, requestCode) } else { context.startActivity(intent) } } else { //跳转Flutter页面 //BoostFlutterActivity 需要在Manifest中注册，也可以继承该Activity进行部分自定义操作 val intent = BoostFlutterActivity.withNewEngine().url(url).params(urlParams).backgroundMode(BoostFlutterActivity.BackgroundMode.opaque).build(context); if (context is Activity) { context.startActivityForResult(intent,requestCode); } else { context.startActivity(intent); } } } - 在FlutterModule中初始化FlutterBoost
class MyApp extends StatefulWidget { @override _MyAppState createState() => _MyAppState(); } class _MyAppState extends State<MyApp> { @override void initState() { super.initState(); //注册路由 FlutterBoost.singleton.registerPageBuilders({ 'flutter_page_1': (pageName, params, _) => FlutterPage1(params), 'flutter_page_2': (pageName, params, _) => FlutterPage2(params), }); } } 至此混合开发框架搭建完成。
- Android跳转Flutter,携带参数，并等待返回数据
//Android,startActivityForResult openFlutter("flutter_page_1", mapOf("data" to "data form native")) { _, data -> //取返回值 val map = data?.getSerializableExtra(IFlutterViewContainer.RESULT_KEY) as? Map<*, *> println("Flutter 返回的数据：${map}") } //Flutter,关闭时返回数据 FlutterBoost.singleton.closeCurrent(result: { 'data': 'data form flutter page1', }); - Flutter跳转Android携带参数，并等待返回数据
//Flutter FlutterBoost.singleton.open("native://native_page_1",urlParams: {"data": "data from flutter page1"}).then((map) { print("原生返回给Flutter的数据:$map"); }); //Android 返回数据给Flutter val result = hashMapOf<String, Any>("data" to "dara form native page1") setResult(Activity.RESULT_OK, Intent().apply { putExtra(IFlutterViewContainer.RESULT_KEY, result) }) finish() - Flutter跳转Flutter携带参数，并等待返回数据
//Fluuter Page 1 FlutterBoost.singleton.open("flutter_page_2",urlParams: {"data": "data from flutter page1"}).then((map) { print("flutter_page_2返回给flutter_page_1的数据：$map"); }); //Fluuter Page 2,关闭时返回数据 FlutterBoost.singleton.closeCurrent(result: { 'data': 'data form flutter page2', });
