flutter 공부 3일차(코딩애플 쉬운 플래터)

화면 배율 정하기

 

container로 바로 정할 수 없다.

 

Flexiable 속성을 이용해야한다.

 children:[
              Flexible(child: Container(color: Colors.blue,),flex: 2,), //배수로
              Flexible(child: Container(color: Colors.lightGreen,),flex: ,),
            ],

 

그리고 숙제 다시해보기

 

import 'package:flutter/material.dart';

void main() {
  runApp(const MyApp()); //앱 실행해주세요!!!! 라는 뜻
}

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
        home: Scaffold( //이게 무슨 형식이고
            appBar: AppBar(actions: [Icon(Icons.search),Icon(Icons.menu),Icon(Icons.doorbell),],
              title: Text("별내동3로" , style: TextStyle(fontWeight:FontWeight.w600) ),
              backgroundColor : Colors.white,
              foregroundColor: Colors.black,
              leading: IconButton(
                  icon: Icon(Icons.arrow_drop_down_circle_outlined),
                  onPressed: () {
                    print('menu button is clicked');
                  }
              ),
            ), //상단바의 텍스트
            body: Container(padding: EdgeInsets.all(10), height: 210,decoration: BoxDecoration(border: Border.all(color:Colors.black12)),
              child:Row(
                children:[
                  //사진
                  Container( margin: EdgeInsets.all(10)  ,child: Image.asset("subin.jpg", )),
                  //오른쪽
                  Container(
                    width: 400,
                    margin: EdgeInsets.all(5)  ,
                    child: Column(
                    crossAxisAlignment: CrossAxisAlignment.start,
                      children: [

                        Text("별내동의 명물!",style: TextStyle(fontSize: 20),),
                      Row(
                        children : [
                        Text("\n별내동" ,)]
                      ),

                      Text("\n\n10,000,000,000원\n" ,),
                      Row(
                        mainAxisAlignment: MainAxisAlignment.end,
                        children: [
                          Icon(Icons.favorite),
                          Text('4'),
                          Text('   '),
                          Icon(Icons.visibility_rounded),
                          Text('128'),

                        ],
                      )




                    ],),

                  )],),




            )
        )
    );


  }
}

 

listview

 

body: ListView(
  children: [
    Text('안녕'),
    Text('안녕'),
    Text('안녕'),
    Text('안녕'),
    Text('안녕'),
    Text('안녕'), Text('안녕'),
