Tap interactions not working on iOS 18.2

[RyanQuigleyOsi]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

Once I interact with any widget in the application that isn't the web view, the webview stops recognizing any tap interaction. I can still scroll and zoom fine. If I reload the controller it fixes things until I touch another widget again.

Expected Behavior

The webview should recognize the webview all the time.

Steps with code example to reproduce

Update your iOS device to the 18.2 and click on any other widget before using attempting to click on anything in a webview

InAppWebView(key: Constants.mapWebViewKey, initialUrlRequest: URLRequest(url: WebUri("https://flutter.dev")),);

Stacktrace/Logs

I'm unable to get any logs related to this issue

Flutter version

3.19.0 and 3.24.4

Operating System, Device-specific and/or Tool

iOS 18.2 beta

Plugin version

6.0.0 and 6.2.0-beta.1

Additional information

I was also able to reproduce this issue with webview_flutter 4.10.0 so I'm thinking this might be a deeper issue with the iOS beta and not the webviews. If anyone has seen something like this before or has any insight it would be much appreciated.

Sorry but starting from 6.1.0, the flutter version required is 3.24.0, so It’s not possible you are using 6.2.0 beta version with 3.19.0.
Also, please post the minimal code to reproduce the issue and, if possible, a screen record of the issue, thanks!

I forgot to add the flutter version to match the 6.2.0 beta but the comment should be updated along with the code I used for the demo video. I tested it on Android as well and it worked like normal.

Have you tried to update to latest Flutter version? Maybe the master branch of Flutter?

[RyanQuigleyOsi]

Updating to flutter master (3.27.0-1.0.pre.494) has the same behavior.

Ok thanks for the test! did you create an issue on the Flutter official repo?

[RyanQuigleyOsi]

I hadn't, but I'll link it here once I do.

Hello,

I am experiencing a similar issue. According to the following GitHub issues (#158961, #159911), it seems that this problem was resolved in Flutter version 3.27.0. It also appears to be working as expected when using webview_flutter. However, I am using flutter_inappwebview version 6.15.0, and the issue persists on iOS 18.2, even with Flutter version 3.27.0.

When the webview is opened, and only its functionalities are used, the tap events work fine. However, if I open a Flutter feature (e.g., a flash bar or a bottom sheet) by interacting with a button inside the webview, the tap events within the webview stop working entirely afterward.

I would greatly appreciate it if you could look into this issue.

Thank you!

Hello, can anyone create a GitHub issue at flutter/flutter and zip a sample project, so I can verify the fix?
