推荐答案

你需要使用 堆栈小部件.

此示例代码显示了您要查找的内容.

This example code shows what you are looking for.

import 'package:flutter/material.dart';

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

  class MyApp extends StatelessWidget {
    @override
    Widget build(BuildContext context) {
      return new MaterialApp(
        debugShowCheckedModeBanner: false,
        title: 'Stack Demo',
        home: new StackDemo(),
      );
    }
  }

  class StackDemo extends StatelessWidget {
    @override
    Widget build(BuildContext context) {
      return Scaffold(
        appBar: AppBar(title: Text('Stack Demo'),),
        body: Stack(
          alignment: Alignment.center,
          children: <Widget>[
            // background image and bottom contents
            Column(
              children: <Widget>[
                Container(
                  height: 200.0,
                  color: Colors.orange,
                  child: Center(
                    child: Text('Background image goes here'),
                  ),
                ),
                Expanded(
                  child: Container(
                    color: Colors.white,
                    child: Center(
                      child: Text('Content goes here'),
                    ),
                  ),
                )
              ],
            ),
            // Profile image
            Positioned(
              top: 150.0, // (background container size) - (circle height / 2)
              child: Container(
                height: 100.0,
                width: 100.0,
                decoration: BoxDecoration(
                  shape: BoxShape.circle,
                  color: Colors.green
                ),
              ),
            )
          ],
        ),
      );
    }
  }
