Flutter 容器(4) - Container

Container 类似于HTML中的div标签

import 'package:flutter/material.dart';

class AuthList extends StatelessWidget {
  @override
  Widget build(BuildContext context) {

    return Scaffold(
      appBar: AppBar(
        title: Text('代码测试'),
        centerTitle: true,
      ),
      body: Container(
        alignment: Alignment.bottomCenter,
        decoration: BoxDecoration(
            border: Border.all(color: Colors.blue, width: 2.0),
            image: DecorationImage(
                image: NetworkImage(
                    'https://bbs.qn.img-space.com/201910/6/85833b8012b9e0a626961e844f531c3d.jpg?imageView2/2/w/1024/q/75/ignore-error/1//'),
                fit: BoxFit.fill),
            borderRadius: BorderRadius.all(Radius.circular(10.0))),
        width: 300.0,
        height: 150.0,
        padding: EdgeInsets.all(30.0),
        margin: EdgeInsets.all(50.0),
        constraints: BoxConstraints.expand(width: 200.0, height: 150.0),
        child: Text(
          'Container demo',
          style: TextStyle(color: Colors.deepOrange),
        ),
      ),
    );
  }
