mediaPlaybackRequiresUserAction is deprecated: first deprecation in iOS 9.0

[MyBuzzTechnologies]

When building my app in Xcode, 2 deprecation warnings are appearing about use of mediaTypesRequiringUserActionForPlayback in webview_flutter component.

Not a serious problem, mainly reported here for reference as it may be removed at some point by Apple on later versions of iOS.

This article explains how to replace it:

Hi @MyBuzzTechnologies
Can you please screenshot this warning? I can't find it in the logs or in Xcode when running the app on iOS using 2.0.0-nullsafety.5

Thank you

A screenshot is included below as requested:

The warnings seem to be in the following method:

- (void)updateAutoMediaPlaybackPolicy:(NSNumber*)policy
                      inConfiguration:(WKWebViewConfiguration*)configuration {
  switch ([policy integerValue]) {
    case 0:  // require_user_action_for_all_media_types
      if (@available(iOS 10.0, *)) {
        configuration.mediaTypesRequiringUserActionForPlayback = WKAudiovisualMediaTypeAll;
      } else {
        configuration.mediaPlaybackRequiresUserAction = true;
      }
      break;
    case 1:  // always_allow
      if (@available(iOS 10.0, *)) {
        configuration.mediaTypesRequiringUserActionForPlayback = WKAudiovisualMediaTypeNone;
      } else {
        configuration.mediaPlaybackRequiresUserAction = false;
      }
      break;
    default:
      NSLog(@"webview_flutter: unknown auto media playback policy: %@", policy);
  }
}

My project uses the default Flutter target of iOS 9.0 - not sure if that is relevant but hope the above helps.
