Adding a splash screen to your mobile app

Add Splash Screen Header

Splash screens (also known as launch screens) provide a simple initial experience while your mobile app loads. They set the stage for your application, while allowing time for the app engine to load and your app to initialize. This guide teaches you how to use splash screens appropriately on iOS and Android.

iOS launch screen

All apps submitted to the Apple App Store must use an Xcode storyboard to provide the app’s launch screen.

The default Flutter template includes an Xcode storyboard named LaunchScreen.storyboard that can be customized as you see fit with your own assets. By default, the storyboard displays a blank image, but you can change this. To do so, open the Flutter app’s Xcode project by typing open ios/Runner.xcworkspace from the root of your app directory. Then select Runner/Assets.xcassets from the Project Navigator and drop in the desired images to the LaunchImage image set.

Apple provides detailed guidance for launch screens as part of the Human Interface Guidelines.

Android launch screen

In Android, there are two separate screens that you can control: a launch screen shown while your Android app initializes, and a splash screen that displays while the Flutter experience initializes.

Initializing the app

Every Android app requires initialization time while the operating system sets up the app’s process. Android provides the concept of a launch screen to display a Drawable while the app is initializing.

The default Flutter project template includes a definition of a launch theme and a launch background. You can customize this by editing styles.xml, where you can define a theme whose windowBackground is set to the Drawable that should be displayed as the launch screen.

<style name="LaunchTheme" parent="@android:style/Theme.Black.NoTitleBar">
    <item name="android:windowBackground">@drawable/launch_background</item>

In addition, style.xml defines a normal theme to be applied to FlutterActivity after the launch screen is gone. The normal theme background only shows for a very brief moment after the splash screen disappears, and during orientation change and Activity restoration. Therefore, it’s recommended that the normal theme use a solid background color that looks similar to the primary background color of the Flutter UI.

<style name="NormalTheme" parent="@android:style/Theme.Black.NoTitleBar">
    <item name="android:windowBackground">@drawable/normal_background</item>

Set up the FlutterActivity in AndroidManifest.xml

In AndroidManifest.xml, set the theme of FlutterActivity to the launch theme. Then, add a metadata element to the desired FlutterActivity to instruct Flutter to switch from the launch theme to the normal theme at the appropriate time.

    // ...
        <action android:name="android.intent.action.MAIN"/>
        <category android:name="android.intent.category.LAUNCHER"/>

The Android app now displays the desired launch screen while the app initializes.

Android S

See Android Splash Screens first on how to configure your launch screen on Android S.

Make sure neither is set in your manifest, nor is provideSplashScreen implemented, as these APIs are deprecated. Doing so will cause the Android launch screen to fade smoothly into the Flutter when the app is launched and you may experience a crash.

Some apps may want to continue showing the last frame of the Android launch screen in Flutter. For example, this preserves the illusion of a single frame while additional loading continues in Dart. To achieve this, the following Android APIs may be helpful:

import android.os.Build;
import android.os.Bundle;
import android.window.SplashScreenView;
import androidx.core.view.WindowCompat;

public class MainActivity extends FlutterActivity {
    protected void onCreate(Bundle savedInstanceState) {
        // Aligns the Flutter view vertically with the window.
        WindowCompat.setDecorFitsSystemWindows(getWindow(), false);

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.S) {
            // Disable the Android splash screen fade out animation to avoid
            // a flicker before the similar frame is drawn in Flutter.
                    (SplashScreenView splashScreenView) -> {

import android.os.Build
import android.os.Bundle
import androidx.core.view.WindowCompat

class MainActivity : FlutterActivity() {
  override fun onCreate(savedInstanceState: Bundle?) {
    // Aligns the Flutter view vertically with the window.
    WindowCompat.setDecorFitsSystemWindows(getWindow(), false)

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.S) {
      // Disable the Android splash screen fade out animation to avoid
      // a flicker before the similar frame is drawn in Flutter.
      splashScreen.setOnExitAnimationListener { splashScreenView -> splashScreenView.remove() }


Then, you can reimplement the first frame in Flutter that shows elements of your Android launch screen in the same positions on screen. For an example of this, see the Android splash screen sample app.
