准备工作

1.创建native工程

app->build.gradle

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

2.创建flutter工程

cd some/path/
 flutter create -t module --org com.example my_flutter

1.引入
1.1源码引入

app->settings.gradle

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

app
dependencies {
implementation project(':flutter')
}

>app->build.gradle

android {
// ...
}

repositories {
maven {
url 'some/path/my_flutter/build/host/outputs/repo'
// This is relative to the location of the build.gradle file
// if using a relative path.
}
maven {
url 'https://storage.googleapis.com/download.flutter.io'
}
}

dependencies {
// ...
debugImplementation 'com.example.flutter_module:flutter_debug:1.0'
profileImplementation 'com.example.flutter_module:flutter_profile:1.0'
releaseImplementation 'com.example.flutter_module:flutter_release:1.0'
}
