在flutter中,我们想在一个页面中放置多个组件,就要使用Container容器组件,Container可以放置内置组件,并设置样式
padding:内边距
margin:外边距
import 'package:flutter/material.dart';
void main() => runApp(MyApp());
class MyApp extends StatelessWidget {
// This widget is the root of your application.
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter',
home: Scaffold(
appBar: AppBar(
title: Text("Hello World"),
),
body: Center(
child: Container(
child: Text(
"Hello Flutterr",
),
color: Colors.yellow,
padding:const EdgeInsets.all(19),
margin: EdgeInsets.fromLTRB(20, 40, 60, 180),
)),
));
}
}
