title: Flutter splash screen android more than one image
body: <p>hei, i have app build with flutter, i implement splashscreen on android with this code and its fully work.</p>
  
  <p>style.xml</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;resources&gt;
      &lt;style name="LaunchTheme" parent="@android:style/Theme.Black.NoTitleBar"&gt;
          &lt;!-- Show a splash screen on the activity. Automatically removed when
               Flutter draws its first frame --&gt;
          &lt;item name="android:windowBackground"&gt;@drawable/launch_background&lt;/item&gt;
          &lt;item name="android:windowFullscreen"&gt;true&lt;/item&gt;
      &lt;/style&gt;
      &lt;style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar"&gt;
          &lt;item name="windowActionBar"&gt;false&lt;/item&gt;
          &lt;item name="windowNoTitle"&gt;true&lt;/item&gt;
      &lt;/style&gt;
  &lt;/resources&gt;
  </code></pre>
  
  <p>and the launch_background.xml</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;layer-list xmlns:android="http://schemas.android.com/apk/res/android"&gt;
      &lt;item android:drawable="@color/company" /&gt;
      &lt;item&gt;
          &lt;bitmap
              android:gravity="fill_horizontal|fill_vertical"
              android:src="@drawable/screen" /&gt;
      &lt;/item&gt;
  &lt;/layer-list&gt;
  </code></pre>
  
  <p>but if i add one more image,its work but, after splasscreen the app force close without error notif in flutter console. so the code look like this
  launch_background.xml</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;layer-list xmlns:android="http://schemas.android.com/apk/res/android"&gt;
      &lt;item android:drawable="@color/company" /&gt;
      &lt;item&gt;
          &lt;bitmap
          android:gravity="fill_horizontal|fill_vertical"
          android:src="@drawable/screen" /&gt;
  &lt;/item&gt;
  &lt;item&gt;
      &lt;bitmap
          android:gravity="center"
          android:src="@drawable/company_icon" /&gt;
  &lt;/item&gt;
  </code></pre>
