Automatically generates native code for adding splash screens in Android and iOS. Customize with specific platform, background color and splash image.

This package is heavily inspired by flutter_launcher_icons created by Mark O'Sullivan and Franz Silva.

Usage

First, add flutter_native_splash as a dev dependency in your pubspec.yaml file. You should add the package to dev_dependencies because you don't need this plugin in your APK.

dev_dependencies:
  flutter_native_splash: ^0.1.9

Don't forget to flutter pub get.

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 omit image parameter if you just want a colored splash screen:

flutter_native_splash:
  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 pub run flutter_native_splash:create

When the package finishes running your splash screen is ready.

Notes

  • If splash screen was not updated properly on iOS or if you experience a white screen before splash screen, run flutter clean and recompile your app. (issue #9)
  • This package modifies launch_background.xml, styles.xml and MainActivity files on Android and LaunchScreen.storyboard, Info.plist and AppDelegate on iOS. If you modified this files manually this plugin may not work properly, please open a issue if you find any bugs.

Recommendations

  • If you want to use a Material Icon as your splash image, download an icon in (material.io/resources/icons) as PNG for Android. I recommend using the biggest icon in drawable-xxxhdpi folder which was just downloaded for better results.
  • Material Colors are available in material.io/resources/color

How it works

Android

  • Your splash image will be resized to mdpi, hdpi, xhdpi, xxhdpi and xxxhdpi drawables.
  • An <item> tag containing a <bitmap> for your splash image drawable will be added in launch_background.xml
  • Background color will be added in colors.xml and referenced in launch_background.xml.
  • Code for full screen mode toggle will be added in styles.xml and MainActivity.

iOS

  • Your splash image will be resized to @3x and @2x images.
  • Color and image properties will be inserted in LaunchScreen.storyboard.
  • Code for hidden status bar toggle will be adde in Info.plist and AppDelegate.
