看看IntrinsicHeight; 包裹根行应该提供您想要的效果：
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: Scaffold(
appBar: AppBar(title: Text('Rows & Columns')),
body: RowsAndColumns(),
),
);
}
}
class RowsAndColumns extends StatelessWidget {
@override
Widget build(BuildContext context) {
return Padding(
padding: const EdgeInsets.only(top: 100.0),
child: IntrinsicHeight(
child: Row(crossAxisAlignment: CrossAxisAlignment.stretch, children: [
Expanded(
child: Column(children: [
Container(height: 120.0, color: Colors.yellow),
Container(height: 100.0, color: Colors.cyan),
]),
),
Expanded(child: Container(color: Colors.Amber)),
]),
),
);
}
}
调整列中容器的高度会导致右侧的容器调整大小以匹配：
