This error happened while running application after new update

Tried overriding flutter_inappweview_android package with older version,

dependency_overrides:
  flutter_inappwebview_android: 1.0.13

then this error gone and app runs but some functionalities not working like in youtube_player_flutter package. Also i have checked this player's source code to ensure it is using latest flutter_inappwebview package.

The folllowing exception also showing i am not sure about this is related to youtube_player_flutter package or flutter_inappwebview package

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!

[ZoftPranav]

any fix for this ? @sagarZodage seems like version is highly unstable

[sagarZodage]

Not Yet . @ZoftPranav Please let me know if anyone find any solution

[pichillilorenzo]

I will try to downgrade to the previous version for the Android native appcompat dependency.

[sagarZodage]

I have also tried but not working below version I am currently working .

    **_'androidx.appcompat:appcompat:1.3.1'_**

[pichillilorenzo]

@sagarZodage which version of Flutter are you using? androidx.appcompat 1.3.1 seems to be pretty old (check https://mvnrepository.com/artifact/androidx.appcompat/appcompat).
The previous version used by the plugin was 1.6.0

[sagarZodage]

Also tried with 'androidx.appcompat:appcompat:1.7.0' version not working

[pichillilorenzo]

@sagarZodage 1.7.0 is the current version, have you tried with 1.6.0? It’s the version used by flutter_inappwebview 6.0.0

[adityapatil18]

@sagarZodage which version of Flutter are you using? androidx.appcompat 1.3.1 seems to be pretty old (check https://mvnrepository.com/artifact/androidx.appcompat/appcompat). The previous version used by the plugin was 1.6.0

I have also tried but not working . Its not the androidx.appcompat issue this issue is occuring becasue of the unstable flutter_inappwebview. and I used this
dependency_overrides:
flutter_inappwebview_android: 1.0.13
still its causing the same issue.

[pichillilorenzo]

Have you tried to upgrade the Android gradle version? Check #2290 (comment)

[ijascookee]

Have you tried to upgrade the Android gradle version? Check #2290 (comment)

Yes, tried...
flutter_inappwebview_android
is using old appcompat version and it is is not supported by latest version of flutter.

[pichillilorenzo]

Released new flutter_inappwebview_android version 1.1.0+1 with the fix. You can run flutter pub upgrade.

[ijascookee]

@pichillilorenzo

[pichillilorenzo]

The SUPPRESS_ERROR_PAGE unsupported feature has been already removed on the new plugin version, so use flutter_inappwebview 6.1.0.
If you are already using 6.1.0, run flutter pub upgrade

Thanks now its working fine😍

[sagarZodage]

I am currently trying to upload a new build to the Google Play Store and have encountered the following issue.

[pichillilorenzo]

@sagarZodage I don’t know what is your zc.b$b.onReceive. You should check your native code or other dependencies.

[JeffTyfoom]

Released new flutter_inappwebview_android version 1.1.0+1 with the fix. You can run flutter pub upgrade.

Thanks it's working!
