flutter SingleChildScrollView的使用的使用
SingleChildScrollView相当于安卓的ScrollView，SizedBox是一个能指定宽高的盒子，一般默认占据主轴空间
import 'package:flutter/material.dart';
class Demo1 extends StatelessWidget{
@override
Widget build(BuildContext context) {
// TODO: implement build
return Scaffold(
appBar: AppBar(
elevation: 0.0,
backgroundColor: Colors.transparent,
title: Text('sdafas',style: TextStyle(fontSize: 14,color: Colors.red),),
),
//类似安卓中的ScrollView
body: SingleChildScrollView(
child: Column(
crossAxisAlignment: CrossAxisAlignment.stretch,
children: [
//可以确定控制盒子大小的widget
SizedBox(height: 36,child:
Container(
decoration: BoxDecoration(
color: Colors.red
),
),),
