Examples
Installation
1. Depend on it
Add this to your package’s pubspec.yaml file:
dependencies: flutter_splash_screen: ^xxx
2. Install it
You can install packages from the command line:
with Flutter:
$ flutter packages get
Alternatively, your editor might support flutter packages get. Check the docs for your editor to learn more.
3. Plugin Configuration
Android
Update the MainActivity.java
to use flutter_splash_screen
via the following changes:
package org.devio.flutter.splashscreen.example; import android.os.Bundle; + import org.devio.flutter.splashscreen.flutter_splash_screen.SplashScreen; import io.flutter.app.FlutterActivity; import io.flutter.plugins.GeneratedPluginRegistrant; public class MainActivity extends FlutterActivity { @Override protected void onCreate(Bundle savedInstanceState) { + SplashScreen.show(this, true);// here super.onCreate(savedInstanceState); GeneratedPluginRegistrant.registerWith(this); } }
iOS
No need for this step.
Getting started
Import it
Now in your Dart code, you can use:
import 'package:flutter_splash_screen/flutter_splash_screen.dart';
Android:
Create a file called launch_screen.xml
in app/src/main/res/layout
(create the layout
-folder if it doesn’t exist). The contents of the file should be the following:
<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent"> <ImageView android:layout_width="match_parent" android:layout_height="match_parent" android:src="@drawable/launch_screen" android:scaleType="centerCrop" /> </RelativeLayout>
Customize your launch screen by creating a launch_screen.png
-file and placing it in an appropriate drawable
-folder. Android automatically scales drawable, so you do not necessarily need to provide images for all phone densities. You can create splash screens in the following folders:
drawable-ldpi
drawable-mdpi
drawable-hdpi
drawable-xhdpi
drawable-xxhdpi
drawable-xxxhdpi
Add a color called primary_dark
in app/src/main/res/values/colors.xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="primary_dark">#000000</color>
</resources>
Optional steps:
If you want the splash screen to be transparent, follow these steps.
Open android/app/src/main/res/values/styles.xml
and add <item name="android:windowIsTranslucent">true</item>
to the file. It should look like this:
<resources> <!-- Base application theme. --> <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar"> <!-- Customize your theme here. --> <!--设置透明背景--> <item name="android:windowIsTranslucent">true</item> </style> </resources>

If you want to customize the color of the status bar when the splash screen is displayed:
Create android/app/src/main/res/values/colors.xml
and add
<?xml version="1.0" encoding="utf-8"?> <resources> <color name="status_bar_color"><!-- Colour of your status bar here --></color> </resources>
Create a style definition for this in android/app/src/main/res/values/styles.xml
:
<?xml version="1.0" encoding="utf-8"?> <resources> <style name="SplashScreenTheme" parent="SplashScreen_SplashTheme"> <item name="colorPrimaryDark">@color/status_bar_color</item> </style> </resources>
Change your show
method to include your custom style:
SplashScreen.show(this, R.style.SplashScreenTheme);
iOS
Customize your splash screen via LaunchScreen.storyboard
,
