下面是我的代码--》 activity代码

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.mm_test_activity);
       /* FragmentTransaction tx = getSupportFragmentManager().beginTransaction();
        tx.replace(R.id.framelayout, Flutter.createFragment("route1"));
        tx.commit();*/
        View flutterView = Flutter.createView(
                MMTestActivity.this,
                getLifecycle(),
                "route1"
        );
        FrameLayout.LayoutParams layout = new FrameLayout.LayoutParams(600, 800);
        layout.leftMargin = 100;
        layout.topMargin = 200;
        addContentView(flutterView, layout);


    }
}

flutter代码：

import 'package:flutter/material.dart';
import 'dart:ui';

void main() => runApp(_getWidget(window.defaultRouteName));
Widget _getWidget(String rounte){
    switch (rounte) {
      case "route1":
        return MyRounte1();
      default:
      return MyHomePage();
    }

  }
  
  class  MyRounte1 extends StatefulWidget{
  @override
  State<StatefulWidget> createState() {
    // TODO: implement createState
    return  _MyRounte1();
  }


}

class _MyRounte1 extends State<MyRounte1> {
  @override
  Widget build(BuildContext context) {
    // TODO: implement build
    return Center(
      child: Text('rounte1'),
      widthFactor: 10,
      heightFactor: 20,
    );
  }

}
