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 got around this by adding flutter_inappwebview_android to the dependency_overrides
dependency_overrides:
flutter_inappwebview_android:
git:
url: https://github.com/holzgeist/flutter_inappwebview
path: flutter_inappwebview_android
ref: d89b1d32638b49dfc58c4b7c84153be0c269d057

I created a temporary package until this problem is resolved here. Maybe it will help some people: https://pub.dev/packages/webview_inapp
I am facing this issue too. But this fixed it for now. I hope the owner releases an update soon.
