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,
