[ [ Flutter 04 ]  Routing  ]

1.Main.dart 에 routes 등록 

import 'package:flutter/material.dart';
import 'package:linker_manager/screens/lauch_screen.dart';
import 'package:linker_manager/screens/main_screen.dart';

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

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

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: const LauchScreen(),
      routes: {
        '/MainPage': (BuildContext context) => const MainScreen(),
      },
    );
  }
}

2.Routing 처리 

Navigator.of(context).pushNamed("/MainPage");

다른방식의 라우팅 

import 'package:flutter/material.dart';
import 'package:toonflix2/screens/detail_screen.dart';

class Webtoon extends StatelessWidget {
  final String title, thumb, id;

  const Webtoon({
    super.key,
    required this.title,
    required this.thumb,
    required this.id,
  });

  @override
  Widget build(BuildContext context) {
    return GestureDetector(
      onTap: () {
        Navigator.push(
          context,
          MaterialPageRoute(
            builder: (context) => DetailScreen(
              title: title,
              thumb: thumb,
              id: id,
            ),
            fullscreenDialog: true,
          ),
        );
      },
      child: Column(
        children: [
          Hero(
            tag: id,
            child: Container(
              width: 250,
              clipBehavior: Clip.hardEdge,
              decoration: BoxDecoration(
                borderRadius: BorderRadius.circular(15),
                boxShadow: [
                  BoxShadow(
                    blurRadius: 15,
                    offset: const Offset(10, 10),
                    color: Colors.black.withOpacity(0.3),
                  )
                ],
              ),
              child: Image.network(
                thumb,
                headers: const {
                  "User-Agent":
                      "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/110.0.0.0 Safari/537.36",
                },
              ),
            ),
          ),
          const SizedBox(
            height: 10,
          ),
          Text(
            title,
            style: const TextStyle(
              fontSize: 22,
            ),
          ),
        ],
      ),
    );
  }
}

위에 위젯 같이 GestureDetector 을 하나만들어서 onTap 이벤트 생성하여 추가 

        Navigator.push(
          context,
          MaterialPageRoute(
