Platform Setup

iOS Configuration

Add the following to ios/Runner/Info.plist for network video support:

<key>NSAppTransportSecurity</key>
<dict>
  <key>NSAllowsArbitraryLoads</key>
  <true/>
</dict>

Android Configuration

Add internet permission to android/app/src/main/AndroidManifest.xml:

<uses-permission android:name="android.permission.INTERNET" />

Important Notes

Always call controller.dispose() in your widget's dispose() method to free up resources
Make sure to handle video loading states appropriately in your UI
Test video playback on actual devices for best performance assessment
