下载flutter

执行flutter_console.bat，执行flutter doctor

在你的Android应用同级路径下执行：

cd some/path/
flutter create -t module --org com.ymbok flutter_moudle

完成后进入到项目路径编译aar：

cd flutter_moudle
flutter build aar

编译完成后在project 的build.gradle添加配置：

buildscript {
    ext.kotlin_version = '1.3.50'
    repositories {
        jcenter()
        google()
    }
    dependencies {
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'com.android.tools.build:gradle:4.1.2'
        classpath "com.alibaba:arouter-register:1.0.2"

    }
}

allprojects {
    repositories {
        google()
        jcenter()
        maven { url 'https://dl.google.com/dl/android/maven2' }
        maven { url "https://jitpack.io" }
        maven {
            url "file:///E:/flutter_module/build/host/outputs/repo"
        }
        maven {
            // libflutter.so 和 libflutter.jar 仓库地址
            url 'http://download.flutter.io'
        }
    }
}

在app的build.gradle中添加配置：

implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"implementation 'com.ymbok.flutter_module:flutter_release:1.0'

创建Activity：

import android.os.Bundle;
import io.flutter.embedding.android.FlutterActivity;

public class FlutterTestActivity  extends FlutterActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }
}

运行即可看到新页面了

从原生跳转到不同的flutter页面：

startActivity(FlutterActivity.withNewEngine().initialRoute("/hello").build(activity));

flutter代码：

import 'package:flutter/material.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      //home: HelloPage(title: 'Home Page'),
      routes: MyRouter.routes,
      initialRoute: MyRouter.helloPage,   //初始页面路由可代替home
    );
  }
}

class MyRouter {

  static final helloPage = '/hello';
  static final detailPage = '/detail';

  static final Map routes = {
    helloPage: (ctx) => HelloPage(title: 'Hello Page'),
    detailPage: (ctx){
      return DetailPage();
    }
  };
}

class HelloPage extends StatefulWidget {
  HelloPage({Key? key, required this.title}) : super(key: key);

  final String title;

  @override
  _HelloPageState createState() => _HelloPageState();

}

class _HelloPageState extends State {

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children:[
            Text(
              'Hello World',
            ),
          ],
        ),
      ),
    );
  }
}
