这是我使用“堆栈”的实现。
因为有一个固定的大小值，我认为它是否是最好的解决方案。

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,
        visualDensity: VisualDensity.adaptivePlatformDensity,
      ),
      home: MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}

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

  final String title;

  @override
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  @override
  void initState() {
    super.initState();
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title),
      ),
      body: _buildBody(),
      floatingActionButton: FloatingActionButton(
        onPressed: () {},
        tooltip: 'Increment',
        child: Icon(Icons.add),
      ),
    );
  }

  Widget _buildBody() {
    return Container(
        height: 70,
        color: Color(0XFFFFA000),
        child: Container(
          margin: EdgeInsets.symmetric(vertical: 10, horizontal: 15),
          child: Stack(
            alignment: Alignment.center,
            children: [
              Row(
                mainAxisSize: MainAxisSize.min,
                children: [
                  Container(
                    padding: EdgeInsets.symmetric(
                      vertical: 5,
                      horizontal: 30,
                    ),
                    margin: EdgeInsets.only(left: 30),
                    decoration: BoxDecoration(
                      color: Colors.black,
                      borderRadius: BorderRadius.circular(5),
                    ),
                    child: Text(
                      'El ilustre',
                      style: TextStyle(
                        fontWeight: FontWeight.bold,
                        color: Colors.white,
                        fontSize: 25,
                      ),
                    ),
                  ),
                  Icon(Icons.arrow_forward, color: Colors.white),
                ],
              ),
              Positioned(
                left: 0,
                child: ClipRRect(
                  borderRadius: BorderRadius.circular(35.0),
                  child: Image.network(
                    'https://i.ibb.co/1vXpqVs/flutter-logo.jpg',
                    width: 50,
                    height: 50,
                    fit: BoxFit.fill,
                  ),
                ),
              )
            ],
          ),
        ));
  }
