CarrotMarketApp - 홈 화면 만들기

1. 기본 셋팅하기

• 파일 구조 잡기

• 구글과 폰트어썸 이모티콘 사용을 위한 셋팅하기

  cupertino_icons: ^1.0.2
  google_fonts: ^6.1.0
  font_awesome_flutter: ^10.5.0
  intl: ^0.18.1

2. 홈 화면 뼈대 만들기

import 'package:flutter/cupertino.dart';

class MainScreens extends StatefulWidget {
  @override
  State<MainScreens> createState() => _MainScreensState();
}

class _MainScreensState extends State<MainScreens> {
  @override
  Widget build(BuildContext context) {
    return Container(
      child: Center(
        child: const Text("MainScreens"),
      ),
    );
  }
}

import 'package:flutter/material.dart';

import 'screens/main_screens.dart';
import 'theme.dart';

void main() {
  runApp(const CarrotMarket());
}

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

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      title: 'carrot_market',
      home: MainScreens(),
      theme: theme(),
    );
  }
}

• 기본 실행앱이 myApp에서 변경되어서 오류가 남

• 이름을 바꿔주면 사용 가능하나 테스트를 할 건 아니라 그냥 삭제하기
