RecipeApp - 풀이2

1. RecipeTitle 커스텀 위젯 만들기

• 모든 위젯에는 제약 조건이 있음

• 컬럼의 부모가 바디 → 바디는 기계마다 다름

• 바디의 크기는 앱바 바로 밑에서 끝까지 = html의 바디와 동일

• 바디 안에 컬럼이 있음

• 컬럼의 제약 조건

• 화면의 크기가 바껴도 재사용 가능함

double.infinity // 부모의 크기까지 늘어남

2. 현재 뷰 확인하기

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

class RecipePage extends StatelessWidget {
  const RecipePage({super.key});

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: _appbar(),
      body: RecipeBody(),
    );
  }

  AppBar _appbar() {
    return AppBar(
      actions: [
        Icon(CupertinoIcons.search), // 시그니처로 키 값 없음
        SizedBox(width: 15),
        Icon(
          CupertinoIcons.heart,
          color: Colors.redAccent,
        ),
        SizedBox(width: 15),
      ],
    );
  }
}

3. Align으로 정렬하기

• ListView는 따로 정렬 키워드를 제공해주지 않음

import 'package:flutter/cupertino.dart';
import 'package:recipe_app2/components/recipe_menu.dart';
import 'package:recipe_app2/components/recipe_title.dart';

class RecipeBody extends StatelessWidget {
  const RecipeBody({
    super.key,
  });

  @override
  Widget build(BuildContext context) {
    return Padding(
      padding: const EdgeInsets.symmetric(horizontal: 30),
      child: ListView(
        children: [
          Align(
            alignment: Alignment.center,
              child: RecipeTitle()),
          RecipeMenu(),
        ],
      ),
    );
  }
}

• Align 사용하기 전 상황

@override
  Widget build(BuildContext context) {
    return Padding(
      padding: const EdgeInsets.only(top: 20),
      child: Row( //1. 메뉴 아이템들의 방향이 수평 방향이기 때문
        mainAxisAlignment: MainAxisAlignment.end,
        children: [
          _buildMenuItem(Icons.food_bank, "ALL"), // 2. 재사용
          SizedBox(width: 25),
          _buildMenuItem(Icons.emoji_food_beverage, "Coffee"), // 3. 재사용
          SizedBox(width: 25),
          _buildMenuItem(Icons.fastfood, "Burger"), // 4. 재사용
          SizedBox(width: 25),
          _buildMenuItem(Icons.local_pizza, "Pizza"), // 5. 재사용
        ],
      ),
    );
  }

4. 이미지와 텍스트 넣기

import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';
import 'package:recipe_app2/components/recipe_menu.dart';
import 'package:recipe_app2/components/recipe_title.dart';

class RecipeBody extends StatelessWidget {
  const RecipeBody({
    super.key,
  });

  @override
  Widget build(BuildContext context) {
    return Padding(
      padding: const EdgeInsets.symmetric(horizontal: 20),
      child: ListView(
        children: [
          RecipeTitle(),
          RecipeMenu(),
          SizedBox(
            width: double.infinity,
            child: Column(
              children: [
                Image.asset("assets/images/coffee.jpeg", fit: BoxFit.cover),
                Text("Coffee", style: TextStyle(fontSize: 20)),
                Text(
                  "Have you ever made your own Coffee? Once you've tried a homemade Coffee, you'll never go back.",
                  style: TextStyle(color: Colors.grey, fontSize: 12),
                ),
              ],
            ),
          )
        ],
      ),
    );
  }
}

import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';
import 'package:recipe_app2/components/recipe_menu.dart';
import 'package:recipe_app2/components/recipe_title.dart';

Widget build(BuildContext context) {
  return Padding(
    padding: const EdgeInsets.symmetric(horizontal: 20),
    child: ListView(
      children: [
        RecipeTitle(),
        RecipeMenu(),
        RecipeListItem(),
      ],
    ),
  );
}
}

class RecipeListItem extends StatelessWidget {
  const RecipeListItem({
    super.key,
  });

  @override
  Widget build(BuildContext context) {
    return SizedBox(
      width: double.infinity,
      child: Column(
        crossAxisAlignment: CrossAxisAlignment.start,
        children: [
          ClipRRect(
              borderRadius: BorderRadius.circular(20),
              child:
              Image.asset("assets/images/coffee.jpeg", fit: BoxFit.cover)),
          Text("Coffee", style: TextStyle(fontSize: 20)),
          Text(
            "Have you ever made your own Coffee? Once you've tried a homemade Coffee, you'll never go back.",
            style: TextStyle(color: Colors.grey, fontSize: 12),
          ),
        ],
      ),
    );
  }
}

• 사진 모서리 라운딩하기

• aspectRatio로 비율을 이용한 크기 조절하기!!

import 'package:flutter/material.dart';
import 'package:recipe_app2/components/recipe_menu.dart';
import 'package:recipe_app2/components/recipe_title.dart';

class RecipeBody extends StatelessWidget {
  const RecipeBody({
    super.key,
  });

  @override
  Widget build(BuildContext context) {
    return Padding(
      padding: const EdgeInsets.symmetric(horizontal: 20),
      child: ListView(
        children: [RecipeTitle(), RecipeMenu(), RecipeListItem()],
      ),
    );
  }

  SizedBox RecipeListItem() {
    return SizedBox(
      width: double.infinity,
      child: Column(
        crossAxisAlignment: CrossAxisAlignment.start,
        children: [
          AspectRatio(
            aspectRatio: 1 / 2, // 비율로 조절하기
            child: ClipRRect(
                borderRadius: BorderRadius.circular(20),
                child: Image.asset("assets/images/coffee.jpeg",
                    fit: BoxFit.cover)),
          ),
          Text("Coffee", style: TextStyle(fontSize: 20)),
          Text(
            "Have you ever made your own Coffee? Once you've tried a homemade Coffee, you'll never go back.",
            style: TextStyle(color: Colors.grey, fontSize: 12),
          ),
        ],
      ),
    );
  }
}

• 나머지 이미지도 넣어주기

• 사진이름과 사진 타이틀을 변수로 사용하기

        ],
      ),
    );
  }
}

class RecipeListItem extends StatelessWidget {
  final imgName;
  final title;

  const RecipeListItem({required this.imgName, required this.title});

  @override

          ),
          Text("Coffee", style: TextStyle(fontSize: 20)),
          Text(
            "Have you ever made your own ${title}? Once you've tried a homemade ${title}, you'll never go back.",
