如上图，做一个抽取

import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';

class RowWidget extends Widget{
  @override
  Element createElement() {
    return  Container(
        width: double.infinity,//充满屏幕
        height: 50.0,
        padding: EdgeInsets.only(left:16.0,top:14.0,right:16.0,bottom:14.0),//内边距，可以一个或者多个使用 .all
        color: Colors.white,
        alignment: Alignment(0,0),
        child: Row(//就是打个样
          children: <Widget>[
            new Image(image: AssetImage("assets/images/check_update.png"),width: 42.0,height: 42.0),
            new Container(child:new Text("检查更新",style: TextStyle(color:Colors.black,fontSize: 16.0,)),
              margin: const EdgeInsets.only(left: 6.0),),

              margin: const EdgeInsets.only(left: 22.0),)
          ],
        )).createElement();
  }
