Flutter.createView 方法已經(jīng)被棄用了 ３性痢Ｔ衿稀ｋ惹选纯丸！

創(chuàng)建原生項目

修改默認布局文件text 為 這是android 原生界面!

添加flutter依賴

原生項目同級目錄下執(zhí)行 以下語句
flutter create -t module flutter_library
androidx 項目也可以使用 flutter create --androidx -t module flutter_library

修改原生項目的setting.gradle 文件

添加一下代碼 并同步

//androidJoinFlutterTest 是本地目錄名可以自行修改
setBinding(new Binding([gradle:this]))
evaluate( new File(
        settingsDir.parentFile,
        'androidJoinFlutterTest/flutter_library/.android/include_flutter.groovy'
))

完成之后會自動生成flutter模塊
并在setting.gradle文件中引用
include ':flutter_library'

修改原生項目app目錄下的build.gradle 文件

android {
 compileOptions{
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}
dependencies {

    implementation project(":flutter")
}

同步完成之后修改MainActivity 的代碼

MainActivity代碼

class MainActivity : AppCompatActivity() {

    private val flutterEngineId = "flutterEngineId"
    private var engine: FlutterEngine? = null

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setTitle("flutter測試頁面")
        setContentView(R.layout.activity_main)

        engine = FlutterEngineCache.getInstance().get(flutterEngineId)
        if (engine == null) {
            engine = FlutterEngine(this)
            engine?.dartExecutor?.executeDartEntrypoint(DartExecutor.DartEntrypoint.createDefault())
            FlutterEngineCache.getInstance().put(flutterEngineId, engine)
        }

        //默認加載flutter的main.dart文件   setInitialRoute 修改初始界面
//        engine.navigationChannel.setInitialRoute()

        val view = createFlutterView()
        view.attachToFlutterEngine(engine!!)
    }

    private fun createFlutterView(): FlutterView {
        val flutterView = FlutterView(this)   
        val params = FrameLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT)
        addContentView(flutterView, params)
        return flutterView
    }

    override fun onResume() {
        super.onResume()
        engine?.lifecycleChannel?.appIsResumed()
    }

    override fun onPause() {
        super.onPause()
        engine?.lifecycleChannel?.appIsInactive()
    }

    override fun onStop() {
        super.onStop()
        engine?.lifecycleChannel?.appIsPaused()
    }
}

flutter依賴也可以把flutter_library打包成arr 原生中依賴arr

打包命令
進入flutter_library目錄 flutter build apk
