原生吧flutter集成进来的办法

google模式：

第一步：项目目录下创建moudle。命令是：flutter create -t module  name    //注意name就是你的module  名称

第二步：setting.gradle 下面加上这么一段话

setBinding(new Binding([gradle:this]))
evaluate(new File(
        settingsDir.parentFile,
        'AndroidMixNativeAndFlutter/flutter_pinbo/.android/include_flutter.groovy'//这个地方是路径，要把项目外层路径也写进去
))

同步之后就创建了module

第三步：app的gradle里面添加依赖

implementation project (':flutter:')

这个是写死的，不会变动，另外如果报错了

Manifest merger failed : uses-sdk:minSdkVersion 15 cannot be smaller than version 16 declared in library [:flutter] I:\android_project\fluter_project\AndroidMixNativeAndFlutter\flutter_pinbo\.android\Flutter\build\intermediates\merged_manifests\debug\processDebugManifest\merged\AndroidManifest.xml as the library might be using APIs not available in 15
    Suggestion: use a compatible library with a minSdk of at most 15,
        or increase this project's minSdk version to at least 16,
        or use tools:overrideLibrary="com.example.flutter_pinbo" to force usage (may lead to runtime failures)

检查一下，两边的sdk设置是否统一

第四部：在原生中就可以这样用了

FlutterView flutterView = Flutter.createView(this, getLifecycle(), "route01");
FrameLayout.LayoutParams layoutParams = new FrameLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
addContentView(flutterView,layoutParams);

出现这样错误：Error: Invoke-customs are only supported starting with Android O (--min-api 26)
flutter支持的版本比较高，老手机无法支持了

另外 gradle wrapper的版本要升级到4.10.1

工具的版本到 classpath 'com.android.tools.build:gradle:3.3.1'

所以这个混合开发，老手机是别玩了
