Flutter Splash screen

Splash screen이라고 하는 앱을 실행했을 때 메인 페이지가 나오기 전 나오는 인트로?를 간단하게 만드는 방법을 알아보겠습니다.

 

먼저 pubspec.yaml에 아래 링크에 라이브러리를 추가해줍니다.

pub.dev/packages/animated_splash_screen

animated_splash_screen | Flutter Package

간단한 예제는 아래와 같습니다.

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

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
        title: 'Flutter Demo',
        theme: ThemeData(
          primarySwatch: Colors.blue,
        ),
        home: AnimatedSplashScreen(
          splash: Image.network(
              'https://cdn.pixabay.com/photo/2021/01/30/12/19/couple-5963678_1280.png'), //스플래쉬 화면에 표시할 위젯
          nextScreen: MyHomePage(
              title: 'Flutter Demo Home Page'), //스플래쉬 화면이 끝나고 표시할 화면(위젯)
          splashTransition: SplashTransition.fadeTransition, //splash에 애니메이션 설정
          splashIconSize: 200, //splash 위젯 크기
          duration: 2000, //애니메이션 속도
          backgroundColor: Colors.pink[50], //스플래쉬 화면에 배경 색깔
        ));
  }
}

//기본 코드
class MyHomePage extends StatefulWidget {
  MyHomePage({Key key, this.title}) : super(key: key);
  final String title;

  @override
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  int _counter = 0;

  void _incrementCounter() {
    setState(() {
      _counter++;
    });
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            Text(
              'You have pushed the button this many times:',
            ),
            Text(
              '$_counter',
              style: Theme.of(context).textTheme.headline4,
            ),
          ],
        ),
      ),
      floatingActionButton: FloatingActionButton(
        onPressed: _incrementCounter,
        tooltip: 'Increment',
        child: Icon(Icons.add),
      ),
    );
  }
}
