The easiest way to add a splash screen in flutter is imho this package: https://pub.dev/packages/flutter_native_splash

Installation guide (by the author of the package):

1. Setting the splash screen

Add your settings to your project's pubspec.yaml file or create a file in your root project folder named flutter_native_splash.yaml with your settings.

flutter_native_splash: image: assets/images/splash.png color: "42a5f5" 

image must be a png file.

You can use # in color as well. color: "#42a5f5" You can also set android or ios to false if you don't want to create a splash screen for a specific platform.

flutter_native_splash: image: assets/images/splash.png color: "42a5f5" android: false 

In case your image should use all available screen (width and height) you can use fill property.

flutter_native_splash: image: assets/images/splash.png color: "42a5f5" fill: true 

Note: fill property is not yet implemented for iOS splash screens.

If you want to disable full screen splash screen on Android you can use android_disable_fullscreen property.

flutter_native_splash: image: assets/images/splash.png color: "42a5f5" android_disable_fullscreen: true 

2. Run the package

After adding your settings, run the package with

flutter pub run flutter_native_splash:create When the package finishes running your splash screen is ready.

Flutter actually gives a simpler way to add Splash Screen to our application. We first need to design a basic page as we design other app screens. You need to make it a StatefulWidget since the state of this will change in a few seconds.

import 'dart:async'; import 'package:flutter/material.dart'; import 'home.dart'; class SplashScreen extends StatefulWidget { @override _SplashScreenState createState() => _SplashScreenState(); } class _SplashScreenState extends State<SplashScreen> { @override void initState() { super.initState(); Timer( Duration(seconds: 3), () => Navigator.of(context).pushReplacement(MaterialPageRoute( builder: (BuildContext context) => HomeScreen()))); } @override Widget build(BuildContext context) { return Scaffold( backgroundColor: Colors.white, body: Center( child: Image.asset('assets/splash.png'), ), ); } } 

Logic Inside the initState(), call a Timer() with the duration, as you wish, I made it 3 seconds, once done push the navigator to Home Screen of our application.

Note: The application should show the splash screen only once, the user should not go back to it again on back button press. For this, we use Navigator.pushReplacement(), It will move to a new screen and remove the previous screen from the navigation history stack.

For a better understanding, visit Flutter: Design your own Splash Screen

There isn't a good example of this yet, but you can do it yourself using the native tools for each platform:

iOS: https://docs.nativescript.org/tooling/publishing/creating-launch-screens-ios

Android: https://www.bignerdranch.com/blog/splash-screens-the-right-way/

Subscribe to issue 8147 for updates on example code for splash screens. If the black flicker between the splash screen and the app on iOS bothers you, subscribe to issue 8127 for updates.

Edit: As of August 31, 2017, improved support for splash screens is now available in the new project template. See #11505.

For Android, go to android > app > src > main > res > drawable > launcher_background.xml

Now uncomment this and replace @mipmap/launch_image, with your image location.

<item> <bitmap android:gravity="center" android:src="@mipmap/launch_image" /> </item> 

You can change the colour of your screen here -

<item android:drawable="@android:color/white" /> 

persons who are getting the error like image not found after applying the verified answer make sure that you are adding @mipmap/ic_launcher instead of @mipmap/ ic_launcher.png

This is the error free and best way to add dynamic splash screen in Flutter.

Both @Collin Jackson and @Sniper are right. You can follow these steps to set up launch images in android and iOS respectively. Then in your MyApp(), in your initState(), you can use Future.delayed to set up a timer or call any api. Until the response is returned from the Future, your launch icons will be shown and then as the response come, you can move to the screen you want to go to after the splash screen. You can see this link : Flutter Splash Screen

You should try below code, worked for me

import 'dart:async'; import 'package:attendance/components/appbar.dart'; import 'package:attendance/homepage.dart'; import 'package:flutter/material.dart'; class _SplashScreenState extends State<SplashScreen> with SingleTickerProviderStateMixin { void handleTimeout() { Navigator.of(context).pushReplacement(new MaterialPageRoute( builder: (BuildContext context) => new MyHomePage())); } startTimeout() async { var duration = const Duration(seconds: 3); return new Timer(duration, handleTimeout); } @override void initState() { // TODO: implement initState super.initState(); _iconAnimationController = new AnimationController( vsync: this, duration: new Duration(milliseconds: 2000)); _iconAnimation = new CurvedAnimation( parent: _iconAnimationController, curve: Curves.easeIn); _iconAnimation.addListener(() => this.setState(() {})); _iconAnimationController.forward(); startTimeout(); } @override Widget build(BuildContext context) { return new Scaffold( body: new Scaffold( body: new Center( child: new Image( image: new AssetImage("images/logo.png"), width: _iconAnimation.value * 100, height: _iconAnimation.value * 100, )), ), ); } } 

Multiple ways you could do this, but the easiest one which I use is:

For Launch Icons I use the flutter library Flutter Launcher Icon

For the Custom Splash Screen I create different Screen resolutions and then add the splash images in the mipmap folder as per the resolution for Android.

The last part is adjusting the launch_background.xml in the drawable folder in res folder in Android.

Just change your code to look like below:

<?xml version="1.0" encoding="utf-8"?> <!-- Modify this file to customize your launch splash screen --> <layer-list xmlns:android="http://schemas.android.com/apk/res/android"> <!-- <item android:drawable="@android:color/white" /> <item android:drawable="@drawable/<splashfilename>" /> --> --> <!-- You can insert your own image assets here --> <item> <bitmap android:gravity="center" android:src="@mipmap/<Your splash image name here as per the mipmap folder>"/> </item> </layer-list> 

Few devs I have seen add the splash as drawable, I tried this but somehow the build fails in Flutter 1.0.0 and Dart SDK 2.0+. Therefore I prefer to add the splash in bitmap section.

iOS Splash-screen creation is rather simpler.

In the Runner folder in iOS just update the LaunchImage.png files with your custom Splash screen images with same names as LaunchImage.png @2x, @3x, @4x.

Just an addition I feel its good to have a 4x image as well in the LaunchImage.imageset. Just update your code in Content.json with following lines, below 3x scale to add a 4x scale option:

{ "idiom" : "universal", "filename" : "[email protected]", "scale" : "4x" } 

Here are the steps for configuring the splash screen in both IOS and Android platforms for your Flutter app.

IOS Platform

All apps submitted to the Apple App Store must use an Xcode storyboard to provide the app’s launch screen. Let’s do this in 3 steps:-

Step 1: Open ios/Runner.xcworkspace from the root of your app directory.

Step 2: Select Runner/Assets.xcassets from the Project Navigator and drag your launch images of all sizes (2x, 3x, etc.). You can also generate different sizes of images from https://appicon.co/#image-sets

Step 3: You can see the LaunchScreen.storyboard file is showing the provided image, here you can also change the position of the image by simply dragging the image. For more information please see official documentation https://developer.apple.com/design/human-interface-guidelines/ios/visual-design/launch-screen/

Android Platform

In Android, a launch screen is shown while your Android app initializes. Let’s set this launch screen in 3 steps:-

Step 1: Open android/app/src/main/res/drawable/launch_background.xml file.

Step 2: At line number 4 you can select the desired colour:-

<item android:drawable="@android:color/white" /> 

Step 3: At line number 10 you can change the image:-

android:src="@mipmap/launch_image" 

That's all, you are done! Happy Coding :)

Adding a page like below and routing might help

import 'dart:async'; import 'package:flutter/material.dart'; import 'package:flutkart/utils/flutkart.dart'; import 'package:flutkart/utils/my_navigator.dart'; class SplashScreen extends StatefulWidget { @override _SplashScreenState createState() => _SplashScreenState(); } class _SplashScreenState extends State<SplashScreen> { @override void initState() { // TODO: implement initState super.initState(); Timer(Duration(seconds: 5), () => MyNavigator.goToIntro(context)); } @override Widget build(BuildContext context) { return Scaffold( body: Stack( fit: StackFit.expand, children: <Widget>[ Container( decoration: BoxDecoration(color: Colors.redAccent), ), Column( mainAxisAlignment: MainAxisAlignment.start, children: <Widget>[ Expanded( flex: 2, child: Container( child: Column( mainAxisAlignment: MainAxisAlignment.center, children: <Widget>[ CircleAvatar( backgroundColor: Colors.white, radius: 50.0, child: Icon( Icons.shopping_cart, color: Colors.greenAccent, size: 50.0, ), ), Padding( padding: EdgeInsets.only(top: 10.0), ), Text( Flutkart.name, style: TextStyle( color: Colors.white, fontWeight: FontWeight.bold, fontSize: 24.0), ) ], ), ), ), Expanded( flex: 1, child: Column( mainAxisAlignment: MainAxisAlignment.center, children: <Widget>[ CircularProgressIndicator(), Padding( padding: EdgeInsets.only(top: 20.0), ), Text( Flutkart.store, softWrap: true, textAlign: TextAlign.center, style: TextStyle( fontWeight: FontWeight.bold, fontSize: 18.0, color: Colors.white), ) ], ), ) ], ) ], ), ); } } 

If you want to follow through, see: https://www.youtube.com/watch?v=FNBuo-7zg2Q

In case you want a secondary splash screen (after the native one), here is a simple example that works:

class SplashPage extends StatelessWidget { SplashPage(BuildContext context) { Future.delayed(const Duration(seconds: 3), () { // Navigate here to next screen }); } @override Widget build(BuildContext context) { return Text('Splash screen here'); } } 

Flutter provides you the ability to have a splash screen by default but there are a lot of plugins that can do the job. If you don't want to use a plugin for the task and you're worried that adding a new plugin might affect your app size. Then you can do it like this.

FOR Android

Open launch_background.xml then you can put in the splash screen image, or gradient color you want. This is the first thing your user sees when they open your app.

For IOS

Open your app using Xcode, Click on Runner > Assest.xcassets > LaunchImage, You can add the image here. If you want to edit what position launch screen image should take or look like you can edit it on LaunchScreen.storyboard.

make your material App like this

=> Add dependency

=> import import 'package:splashscreen/splashscreen.dart';

import 'package:flutter/material.dart'; import 'package:splashscreen/splashscreen.dart'; import 'package:tic_tac_toe/HomePage.dart'; void main(){ runApp( MaterialApp( darkTheme: ThemeData.dark(), debugShowCheckedModeBanner: false, home: new MyApp(), ) ); } class MyApp extends StatefulWidget { @override _MyAppState createState() => new _MyAppState(); } class _MyAppState extends State<MyApp> { @override Widget build(BuildContext context) { return new SplashScreen( seconds: 6, navigateAfterSeconds: new HomePage(), title: new Text('Welcome', style: new TextStyle( fontWeight: FontWeight.bold, fontSize: 26.0, color: Colors.purple, ), ), image: Image.asset("images/pic9.png"), backgroundColor: Colors.white, photoSize: 150.0, ); } } 

The final screen output like this you can change second according to your requirements the circle will be round circular

The Simplest way to do that is by using flutter_native_splash package

First of all, add it to your dev dependencies:

dev_dependencies: flutter_native_splash: ^1.3.1 # make sure to us the latest version 

Now, you can configure your splash screen as you like:

 flutter_native_splash: android: true # show for android, you may set it to false ios: true # show for IOS, you may set it to false image: assets\logo.png # the default image for light and dark themes. Until now, images should be png images image_dark: aassets\logo_dark.png # It will override the 'image' in the dark mode color: "#ffffff" # the default color for light and dark themes color_dark: "#0a0a0a" # will override the 'color' in the dark mode android_gravity: fill # make the image fill the screen for android ios_content_mode: scaleAspectFill # make the image fill the screen for android 

After doing so, run:

flutter clean && flutter pub get && flutter pub run flutter_native_splash:create 

You will notice that ".\android\app\src\main\res*" have changed and the new splash screen was added.

The code from Jaldhi Bhatt doesn't works for me.

Flutter throws a 'Navigator operation requested with a context that does not include a Navigator.'

I fixed the code wrapping the Navigator consumer component inside of another component that initialize the Navigator context using routes, as mentioned in this article.

import 'dart:async'; import 'package:flutter/material.dart'; import 'package:my-app/view/main-view.dart'; class SplashView extends StatelessWidget { @override Widget build(BuildContext context) { return new MaterialApp( home: Builder( builder: (context) => new _SplashContent(), ), routes: <String, WidgetBuilder>{ '/main': (BuildContext context) => new MainView()} ); } } class _SplashContent extends StatefulWidget{ @override _SplashContentState createState() => new _SplashContentState(); } class _SplashContentState extends State<_SplashContent> with SingleTickerProviderStateMixin { var _iconAnimationController; var _iconAnimation; startTimeout() async { var duration = const Duration(seconds: 3); return new Timer(duration, handleTimeout); } void handleTimeout() { Navigator.pushReplacementNamed(context, "/main"); } @override void initState() { super.initState(); _iconAnimationController = new AnimationController( vsync: this, duration: new Duration(milliseconds: 2000)); _iconAnimation = new CurvedAnimation( parent: _iconAnimationController, curve: Curves.easeIn); _iconAnimation.addListener(() => this.setState(() {})); _iconAnimationController.forward(); startTimeout(); } @override Widget build(BuildContext context) { return new Center( child: new Image( image: new AssetImage("images/logo.png"), width: _iconAnimation.value * 100, height: _iconAnimation.value * 100, ) ); } } 

For Android, go to this path,

android > app > src > main > res > drawable > launcher_background.xml

default code is for white colour background screen. like this,

<!-- You can insert your own image assets here --> <item> <bitmap android:gravity="center" android:src="@mipmap/launch_image" /> </item> 

You can changes its color or modify this by adding icon or any custom design. for more customisation detail checkout this for android.

for Ios

open Ios project in Xcode.

select Runner and then.inside Runner folder Main.Storyboard file is there, enter image description here

by default its colour is white, you can customise or change colour this by your requirement, for more customisation check out this Ios.

For Android
app -> src -> main -> res ->drawble->launch_background.xml and uncomment the commented block like this

<item> <bitmap android:gravity="center" android:src="@mipmap/launch_image" /></item> 

is there any one face any error after coding like this
Use sync with system in android studio or invalidate cache and reset.This solved my problem In flutter debug mode take some time take for splash screen .After build it will reduce like native android

What you can do is match the flutter default splash color with your custom flutter (widget class) splash. As you cannot override the default native splash

<?xml version="1.0" encoding="utf-8"?> <!-- Modify this file to customize your launch splash screen --> <layer-list xmlns:android="http://schemas.android.com/apk/res/android"> <!-- <item android:drawable="@android:color/white" /> --> <item android:drawable="@color/custom_color" /> <!-- // Modified \\ --> <!-- You can insert your own image assets here --> <!-- <item> <bitmap android:gravity="center" android:src="@mipmap/launch_image" /> </item> --> </layer-list> 

Flutter.dev already gives the best answer for it, that is not a bug neither a problem, just config. Just take time read and everything will be solved. Have a nice day everyone.

https://flutter.dev/docs/development/ui/advanced/splash-screen

You can create it two ways

1. Go to the native package and an initial page. like in Native Android package create a drawable
2. Create a dart screen to display for some time

I found a complete explanation for remove white screen and display splash screen here

when we have to get user location or other data before app start we can use custom splash screen in flutter and it will make your app user friendly

Here is code Example:-

import 'package:flutter/material.dart'; import 'package:bmi/HomePage.dart'; import 'dart:async'; main(){ runApp(MyApp()); } class MyApp extends StatelessWidget{ @override Widget build(BuildContext context) { return SplashScreen(); } } class SplashScreen extends StatefulWidget{ @override State<StatefulWidget> createState() { return SplashScreenState(); } } class SplashScreenState extends State<SplashScreen>{ @override void initState() { super.initState(); when we have to get data we can show splash Like this:- FutureMethodForData.then((value) { Navigator.push( context, MaterialPageRoute( builder: (context) => HomePage(), ) ); }); Or we can show splash for fix duration like this:- Future.delayed( Duration( seconds: 4 ), (){ Navigator.push( context, MaterialPageRoute( builder: (context) => HomePage(), ) ); } ); } @override Widget build(BuildContext context) { return MaterialApp( home: Scaffold( backgroundColor: Colors.red, body: // add image text or whatever you want as splash ), ); } } 

For people following the steps to the letter like I was and still not getting it to work...

Pay attention if you have a drawable-v21 folder as you need to copy your code from drawable folder > launch_background.xml code into the drawable-v21 folder > launch_background.xml

And my project didn't like android:src="@mipmap/launch" />

Therefore I have android:src="@drawable/launch" />

SplashScreen( seconds: 3, navigateAfterSeconds: new MyApp(), // title: new Text( // 'Welcome In SplashScreen', // style: new TextStyle(fontWeight: FontWeight.bold, fontSize: 20.0), // ), image: new Image.network('https://upload.wikimedia.org/wikipedia/commons/thumb/b/bd/Tesla_Motors.svg/1200px-Tesla_Motors.svg.png'), backgroundColor: Colors.white, styleTextUnderTheLoader: new TextStyle(), photoSize: 150.0, loaderColor: Colors.black), ), );
