Build a Splash Screen in Flutter

Build a Splash Screen in Flutter

A splash screen is the first screen users see when launching your app. It’s an opportunity to create a lasting first impression and handle initial app loading tasks. This guide will show you how to create an engaging splash screen in Flutter.

Why Use a Splash Screen?

Splash screens serve multiple purposes:

• Brand introduction
• Initial loading time
• Resource initialization
• User engagement

Implementation Steps

1. Basic Splash Screen Structure

   class SplashScreen extends StatefulWidget {
     @override
     _SplashScreenState createState() => _SplashScreenState();
   }
   
   class _SplashScreenState extends State<SplashScreen> {
     @override
     void initState() {
       super.initState();
       _navigateToHome();
     }
   
     _navigateToHome() async {
       await Future.delayed(Duration(seconds: 3));
       Navigator.pushReplacement(
         context,
         MaterialPageRoute(builder: (context) => HomeScreen()),
       );
     }
   
     @override
     Widget build(BuildContext context) {
       return Scaffold(
         body: Center(
           child: Column(
             mainAxisAlignment: MainAxisAlignment.center,
             children: [
               Image.asset('assets/logo.png'),
               SizedBox(height: 20),
               CircularProgressIndicator(),
             ],
           ),
         ),
       );
     }
   }
   

2. Add Animations

   class _SplashScreenState extends State<SplashScreen>
       with SingleTickerProviderStateMixin {
     late AnimationController _controller;
     late Animation<double> _animation;
   
     @override
     void initState() {
       super.initState();
       _controller = AnimationController(
         duration: Duration(seconds: 2),
         vsync: this,
       );
       _animation = CurvedAnimation(
         parent: _controller,
         curve: Curves.easeIn,
       );
       _controller.forward();
     }
   
     @override
     Widget build(BuildContext context) {
       return Scaffold(
         body: Center(
           child: FadeTransition(
             opacity: _animation,
             child: Image.asset('assets/logo.png'),
           ),
         ),
       );
     }
   }
