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 am having this issue and i'm not using the inappwebview. I wonder if it is related?

[Kashifalaliwala]

Any updates?

[amitrotner]

Any updates? I'm getting this error too in InAppWebView (I'm not using HeadlessInAppWebView) and this leads to a blank white page instead of the requested page. Moreover, it happens randomly - sometimes it works as expected and load the requested page and sometimes I get this error.

[kraa]

Any updates? I'm getting this error in InAppWebView without using HeadlessInAppWebView

[arneke]

I've stopped using a global key for the webview. (On reviewing, I do use global keys, but I create a new one for each generation.)

Afaict inappwebview (or the underlying webview for that matter) doesn't notice when the view (or some part of it, there are multiple processes) gets garbage collected due to the device going to sleep etc. I don't think there's a way to prevent it either.

You get the white page when the render process associated with the webview has been killed.

Since I use bloc I increment a "generation" counter which causes the builder to create a new inappwebview. I do this whenever I detect a problem, so the user gets a new webview quickly. For a smooth user experience this requires that you maintain most of the state outside of the webview, and that you have a way to transfer the state back into the webview.

I did all my testing on Flutter 2.x, not re-tested all the problems after upgrading to 3.x

The webview seems to be deallocated when error occurs so the onLoadError method is not called. How do you detect problems?

[arneke]

Implementing androidOnRenderProcessGone and iosOnWebContentProcessDidTerminate , and have them trigger mapGenerationCubit.increment() probably covers 95% of the cases.

My app frequently sends updates to the webview, so I also have watchdog timer there. Every time I send a message to the webview, if I don't see an ack within X seconds I start over.

Thanks! In my case iosOnWebContentProcessDidTerminate is not called. The problem occurs high frequently after the app launches in release mode on Flutter 3.0.1. When I switch tab and back to the webview, all content show without loading progress. It acts normally in debug or profile mode.

[arneke]

(No need to quote when you are replying to the comment directly above.)

I think you need a physical device not attached to power to trigger this. Lock the screen and wait 30 sec.

If you run the iOS simulator the webview process is visible in mac os, so you can kill it manually to simulate.

[Zeming404]

I will try it. It's odd that If I run directly in vscode on my iphone xr, it's hard to reproduce the problem. But if I build general app through fastlane, the problem is easy to reproduce.

Hello Team, Any solution to this?

Facing the same issue on iOS 16.0.2 devices. It's happening only in the builds. The page goes blank white.

[Chirag-kalsariya]

Facing same issue

[Cotspheer]

Same here, on my side this happens in combination using Azure B2C on the InAppWebView and users try to "Sign in with Apple". So this is kinda mission critical as it prevents users from signing in. Upgrading to the latest beta version and enabling "Background processing" within "Background modes" on "Signing & Capabilities" in Xcode did help. Recent iOS-Updates did change something so my assumption is that the underlaying WebKit implementation now recognises apple.com URLs and tries to launch the native "Sign in with Apple" flow. I'm 100% sure that this was not the case couple months ago and our users were redirected within the web view to Apples Web-OAuth-Flow.

Changed version from _flutterinappwebview: ^5.7.1+2 to _flutterinappwebview: 6.0.0-beta.22. Not sure what's the key difference in 6.0.0, so maybe a dependency was updated or a bug was fixed that lead to the disposal of the WebView.

Anyhow, after the changes the native "Sign in with Apple" is launched properly and the WebView continues when getting redirected. Before it lead to an "onLoadError" call what basically ended the journey.

any solution ?

Any updates on this?

[aaronbalthaser]

I am getting the same issue and I wasn't even aware I was using a Webviewe. Does anyone know if it is ok to have these issues in the app. Will this cause memory leaks or any other problems with a production application?
