I have an app that needs to play Google Drive videos preview, using webview_flutter plugin, the thumbnail appears but when I tap play I get the errors below:

**Code:**

```dart
String url = 'https://drive.google.com/file/d/1O8WF2MsdyoKpQZE2973IFPRpqwKUjm_q/preview';

           WebView(
                onWebViewCreated: (WebViewController controller){

                  webViewController = controller;

                },
                initialUrl: url,
                javascriptMode: JavascriptMode.unrestricted,
                initialMediaPlaybackPolicy: AutoMediaPlaybackPolicy.always_allow,
              ),
```

**Errors:**

```
