Android集成FlutterModule

1、新建一个Flutter Module

 注意：Android项目和Flutter项目在同一个文件夹；

这时flutter项目就不需要动了，开始动Android项目；

2、MyFlutterAndroidDemo/settings.gradle中添加：

setBinding(new Binding([gradle: this]))
evaluate(new File(
        settingsDir,
        '../flutter_m1/.android/include_flutter.groovy'
))

MyFlutterAndroidDemo/app/build.gradle中添加

 implementation project(path: ':flutter')

【 implementation project(path: ':flutter') 写法是固定的 ， 不要写成 implementation project(path: ':flutter_m1') 】

3、把FlutterActivity添加到清单文件AndroidManifest中

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

打开FlutterActivity就可以跳转了；

 startActivity(new Intent(MainActivity.this , FlutterActivity.class));

遇到的问题：

Caused by: org.gradle.api.internal.plugins.PluginApplicationException: Failed to apply plugin class 'FlutterPlugin'.

修改Android项目settings.gradle

repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
修改为：
​​​​​​​repositoriesMode.set(RepositoriesMode.PREFER_PROJECT)

build.gradle添加

allprojects {
    repositories {
        google()
        mavenCentral()
    }
}
