iOS WebView Does Not Persist Camera and Mic Permission Status in In-App Webview

[7ANV1R]

Expected Behavior:

The WebView should remember the previously granted camera and microphone permissions, and not prompt the user again for permission.

Actual Behavior:

On iOS, the WebView asks for camera and microphone permissions every time the app is launched, and the video meeting page is accessed within the WebView. The permission status is not persisted across app sessions.

Additional Information:
This issue is specific to iOS and is not observed on Android devices. The behavior is consistent across different versions of iOS.

Code:

 Positioned.fill(
            child: InAppWebView(
              initialUrlRequest: URLRequest(
                url: Uri.parse(widget.url),
              ),
              onWebViewCreated: (controller) {
                webViewController = controller;
              },
              initialOptions: InAppWebViewGroupOptions(
                ios: IOSInAppWebViewOptions(
                  allowsInlineMediaPlayback: true,
                  allowsAirPlayForMediaPlayback: true,
                ),
                crossPlatform: InAppWebViewOptions(
                  // Assign the permissionRequestHandler function
                  mediaPlaybackRequiresUserGesture: false,
                ),
              ),
              androidOnPermissionRequest:
                  (InAppWebViewController controller, String origin, List<String> resources) async {
                return PermissionRequestResponse(
                  resources: resources,
                  action: PermissionRequestResponseAction.GRANT,
                );
              },
              onLoadStart: (controller, url) {
                isLoading.value = true;
              },
              onLoadStop: (controller, url) {
                isLoading.value = false;
              },
            ),
          ),

Environment:

Flutter Version: 3.10
iOS Version: 15.7
Device: iPhone 7
flutter_inappwebview: 5.7.2+3

Notes:
This issue affects user experience, as users are prompted for camera and microphone permissions every time they access the video meeting page within the WebView on iOS devices. It is essential to ensure a smoother and more streamlined user experience by persisting the permission status across app sessions on iOS.

Are you sure you have already searched for the same problem?

Some people open new issues but they didn't search for something similar or for the same issue. Please, search for it using the GitHub issue search box or on the official inappwebview.dev website, or, also, using Google, StackOverflow, etc. before posting a new one. You may already find an answer to your problem!

If this is really a new issue, then thank you for raising it. I will investigate it and get back to you as soon as possible. Please, make sure you have given me as much context as possible! Also, if you didn't already, post a code example that can replicate this issue.

In the meantime, you can already search for some possible solutions online! Because this plugin uses native WebView, you can search online for the same issue adding android WebView [MY ERROR HERE] or ios WKWebView [MY ERROR HERE] keywords.

Following these steps can save you, me, and other people a lot of time, thanks!

I'm also having the same problem

It is an IOS webkit behavior and cannot be escaped. If you are using camera and mic in your app using webkit, it will always ask for permission.
Update down below

Is this still the expected behavior? Kind of frustrating, I assume its because there is no persistence with a webview, similar to how private mode works?

[7ANV1R]

@willsmanley if you still got the issue try to add directly flutter_inappwebview_ios for ios and flutter_inappwebview_android for android. this might help.
for me this works back then. try to explore how to use them.

i thinks the problem is not properly implemented iOS WKWebView and Android WebView, which will preserve the permission state.
for webview_flutter package use webview_flutter_wkwebview and webview_flutter_android plugin.

This can be done. At least in native swift.

class Coordinator:NsObject, WKUIDelegate,...{
     func webView(
          _ webView: WKWebView,
          requestMediaCapturePermissionFor
          origin: WKSecurityOrigin, initiatedByFrame
          frame: WKFrameInfo,
          type: WKMediaCaptureType,
          decisionHandler: @escaping (WKPermissionDecision) -> Void) {
              print("Did come here")
              decisionHandler(.grant)
         }

....
}
func makeUIView(){
.....
webView.uiDelegate = context.coordinator
}

With this, when you come back, it wont ask for permission again as you have default granted it.
