1.创立一个flutter module

flutter create -t module --org com.example my_flutter

2.在原生build.gradle下

android {  //...  compileOptions {    sourceCompatibility 1.8    targetCompatibility 1.8  }}

3.增加Flutter模块作为依赖项

有两种形式

（1）无需装置flutter sdk

Flutter库打包为由AAR和POM工件组成的通用本地Maven存储库，

（2） 须要装置sdk

原生settings.gradle下增加

// Include the host app project.include ':app'                                    // assumed existing contentsetBinding(new Binding([gradle: this]))                                // newevaluate(new File(                                                     // new  settingsDir.parentFile,                                              // new  'my_flutter/.android/include_flutter.groovy'                         // new))

原生build.gradle下

dependencies {  implementation project(':flutter')}

4.AndroidManifest.xml

<activity  android:name="io.flutter.embedding.android.FlutterActivity"  android:theme="@style/LaunchTheme"  android:configChanges="orientation|keyboardHidden|keyboard|screenSize|locale|layoutDirection|fontScale|screenLayout|density|uiMode"  android:hardwareAccelerated="true"  android:windowSoftInputMode="adjustResize"  />

@style/LaunchTheme 批改

5.启动

package com.example.myapplicationimport androidx.appcompat.app.AppCompatActivityimport android.os.Bundleimport io.flutter.embedding.android.FlutterActivityclass MainActivity : AppCompatActivity() {    override fun onCreate(savedInstanceState: Bundle?) {        super.onCreate(savedInstanceState)        //setContentView(R.layout.activity_main)        FlutterActivity.createDefaultIntent(this)        startActivity(            FlutterActivity                .withNewEngine()                .initialRoute("/")                .build(this)        )    }}
