Create launch_screen.xml file
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"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent" android:layout_height="match_parent"
android:background="@android:color/white">

<ImageView android:layout_width="match_parent" android:layout_height="match_parent"
android:layout_gravity="center|top" android:scaleType="centerCrop"
android:src="@mipmap/launch_screen" />
</FrameLayout>

Customize your launch screen by creating a launch_screen.png-file and placing it in an
appropriate mipmap-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:

mipmap-ldpi
mipmap-mdpi
mipmap-hdpi
mipmap-xhdpi
mipmap-xxhdpi
mipmap-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>
copied to clipboard
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>

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">


<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"></color>
</resources>
copied to clipboard
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);
