title: Unable to load map_view on fullscreen on Flutter
body: <p>I have an issue when I try to load a google map in fullscreen.
  I have followed all the docs in pub.dartland.org for map_view :</p>
  
  <p>in my AndroidManifest.xml I had :</p>
  
  <pre><code>&lt;uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/&gt;
  &lt;uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/&gt;
  </code></pre>
  
  <p>Also added :</p>
  
  <pre><code> &lt;meta-data android:name="com.google.android.maps.v2.API_KEY" android:value="your_api_key"/&gt;
   &lt;meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version"/&gt;
  </code></pre>
  
  <p>Of course with the apiKey changed, and also :</p>
  
  <pre><code>&lt;activity android:name="com.apptreesoftware.mapview.MapActivity" android:theme="@style/Theme.AppCompat.Light.DarkActionBar"/&gt;
  </code></pre>
  
  <p>I also add the kotlin dependencies in build.graddle.
  So now I can see the staticUri map on the device, great, but when I tap on this map to get it in fullscreen, the app crash with this error :</p>
  
  <pre><code>D/AndroidRuntime( 4373): Shutting down VM
  E/AndroidRuntime( 4373): FATAL EXCEPTION: main
  E/AndroidRuntime( 4373): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.apptreesoftware.mapview.MapActivity}: android.view.InflateException: Binary XML file line #2: Binary XML file line #2: Error inflating class fragment

  </code></pre>
  
  <p>I tried by adding :</p>
  
  <pre><code>&lt;meta-data android:name="com.google.android.geo.API_KEY" android:value="xxxxxxxxxxxxxxx"/&gt;
  </code></pre>
  
  <p>But same issue, maybe someone have an idea ?</p>
  
  <p>EDIT :
  Here is my AndroidManifest.xml :</p>
  
  <pre><code>&lt;manifest xmlns:android="http://schemas.android.com/apk/res/android"
