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!

[makinghappen]

yes, example is outdated, although it is not hard to modify it to match the current version

[JobiJoba]

What do you think it need to be updated and make it working?
I did a strict minimal example and it's not working - This code is working on Android without any issues

class _MyAppState extends State<MyApp> {
  final GlobalKey webViewKey = GlobalKey();

  InAppWebViewController? webViewController;
  InAppWebViewSettings settings = InAppWebViewSettings(
      useShouldOverrideUrlLoading: true,
      mediaPlaybackRequiresUserGesture: false,
      allowsInlineMediaPlayback: true,
      iframeAllow: "camera; microphone",
      iframeAllowFullscreen: true);

  String url = "";
  double progress = 0;

  @override
  Widget build(BuildContext context) {
    return Scaffold(
        appBar: AppBar(title: Text("Official InAppWebView website")),
        body: SafeArea(
            child: Column(children: <Widget>[
          Expanded(
            child: Stack(
              children: [
                InAppWebView(
                  key: webViewKey,
                  initialUrlRequest:
                      URLRequest(url: WebUri("https://inappwebview.dev/")),
                  initialSettings: settings,
                  onWebViewCreated: (controller) {
                    webViewController = controller;
                  },

                        action: PermissionResponseAction.GRANT);
                  },
                  onReceivedError: (controller, request, error) {
                    print("error");
                  },
                  onProgressChanged: (controller, progress) {
                    setState(() {
                      this.progress = progress / 100;
                    });
                  },
                  onConsoleMessage: (controller, consoleMessage) {
                    print(consoleMessage);
                  },
                ),
                progress < 1.0
                    ? LinearProgressIndicator(value: progress)

Hi, When I saw the new version I try again with this simple example but it's still not working on iOS (Simulator) - Where the version 5.8.0 is working.

Any idea?

[Kurokirisu]

This is still an issue. Version 5.8 works fine, but as soon as I migrate to version 6.0, iOS stops working. It just shows a blank screen. Android works fine.

[ciripel]

I also have same issue on version 6.0.0

[mashoodpv]

i am also having same issue with 6.0.0, works with 5.8.0. Hope to get fixed soon..

[serjsv87]

I also have this problem. very much waiting forward to it as very well developed rights to camera and microphone with webrts and on android everything works well but on ios it does not load (((

[aquinoartur]

in my case, the initial url was without an "https" scheme, when added it worked fine again

I had already tested versions 5.7.2+3, 5.8.0 and 6.0.0 and the problem persisted in both, but when I added https everything was fine

[serjsv87]

It doesn't work in my case, maybe the problem is in the simulator or the processor (M2).
still not working, maybe someone has a solution?

i try in stable version 6.0.0.

[EArminjon]

(I got the issue, i rebooted my MacOS and then it was working again as expected... Weird)

[hasankarli]

If you are missing this Info.plist file for non https urls or caching, stream audio sources

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

When change your info.plist data, you need to restart phone or simulator. I don't know why clearly. But its works for me.

[tashfeenzaidi]

I'm also getting the same issue on package version 6.0.0 and on iOS version 17.5, it shows strange behavior. it opens the URL when I click the link button a second time. On the first attempt, it say
sslError: {message: Indicates the evaluation succeeded and the certificate is implicitly trusted, but user intent was not explicitly specified., code: 4}
and a blank screen appears.

[Sumit258000]

Are there any updates on this? I am facing the same issue working perfectly in android, but on iOS it shows an empty page. @pichillilorenzo

[andrewiankidd]

The solution posted by @ddty2 in this thread worked for me:
#2013 (comment)

InAppWebView(
  initialSettings: InAppWebViewSettings(
    useHybridComposition: true,
    javaScriptEnabled: true,
    useShouldOverrideUrlLoading: true,
  ),
  shouldOverrideUrlLoading: (controller, action) async {
    return NavigationActionPolicy.ALLOW;
  },
)

[baophan96-tnm]

I also have same issue on version 6.1.0

[pichillilorenzo]

If you set useShouldOverrideUrlLoading: true and then you don’t implement the shouldOverrideUrlLoading event, then it doesn’t make any sense. The default behaviour will block the request.

So, you should remove useShouldOverrideUrlLoading completely from the WebView settings if you are not using the shouldOverrideUrlLoading event.

[Alex-esc1]

I also have same issue on version 6.1.3
It’s strange that it works on iOS 18, but in versions below the white screen nothing loads
