How to use the flutter native splash screen

I am facing trouble using the flutter native splash screen.A blank screen appears when i tried to use the flutter_native_splash package https://pub.dev/packages/flutter_native_splash

The actual and perfect way is not to add a page or use a plugin, you can even do it natively by this method: Go to => andoid > app > main > res > drawable > in this folder you can see a file called lauch_background open it,

<?xml version="1.0" encoding="utf-8"?>
 <!-- Modify this file to customize your launch splash screen -->
 <layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@android:color/white" />

  <!-- You can insert your own image assets here -->
   <item>
    <bitmap
        android:gravity="fill"
        android:src="@mipmap/ic_launcher" />
  </item>
   </layer-list>

add your image in the folder and rename the image file name to ic_launcher. Also uncomment the commented code in the file.
