This bug only occurs from flutter version 3.19. Flutter version 3.16.9 works perfectly.
I think it's related to this bug: #144278
Then I created a new build of the android engine from flutter version 3.24.5 in the following commit and fixed the above problem:

fix: gesture blocked in android webview after zoom
darshankawar commentedon May 27, 2025
@letrungdo This repo isn't available as I get 404.
3.24.5 is still an old version. Have you also checked running the code on latest stable (3.32.0) and does it replicate on it ?
letrungdo commentedon May 27, 2025
@darshankawar Thanks for your feedback, version 3.32.0 has the same error.
I have set publish for this repo: https://github.com/letrungdo/flutter_webview_issue
darshankawar commentedon May 27, 2025
@letrungdo I cloned the repo and ran it in S10+ device (Android 11) with latest stable version but I wasn't able to tap on any action buttons as shown in video:
Screen_Recording_20250527_161545.mp4
Anything am I missing to properly replicate it ?
letrungdo commentedon May 27, 2025
@darshankawar
wasn't able to tap on any action buttonsThat's what I need to say in this issue. You have reproduced it.
If when opening the app you don't zoom the map, you will be able to tap the buttons
darshankawar commentedon May 28, 2025
Ok, thanks for the update. With that explaination, I was able to replicate the reported behavior.

Hi team,
We're experiencing this issue in our production app. After users use pinch-to-zoom in WebView, all button interactions become completely unresponsive, forcing users to restart the app.
This issue has been labeled as P1 for a month now. Could someone from the team provide an update on:
Thanks for your hard work on Flutter! 🙏

fix: gesture blocked in android webview after zoom (#177572)
gmackall commentedon Nov 14, 2025
I believe this was fixed by #177572
Please re-open if you experience otherwise!
letrungdo commentedon Nov 14, 2025
@gmackall Thank you so much!
I'm still waiting for engine-flutter-autoroll to merge the PR engines, but it seems that the master branch has not yet applied the engine of this fix.
I wonder if this fix will be available in the upcoming flutter 3.38.x version?
gmackall commentedon Nov 14, 2025
@letrungdo Since the merge of flutter/engine into flutter/flutter, you no longer need to wait for engine changes to be rolled in. The master branch should currently contain this fix (the roller you are linking there is rolling the flutter version in use in the flutter/packages repo).
It missed the cut for 3.38.1, but I can look in to seeing if we can cherry pick this into 3.38.2. It is a somewhat risky change though, so not sure if it will be approved.
letrungdo commentedon Nov 14, 2025
@gmackall Thanks for useful information.
I used
fvm use masterand tested again, the bug is still not fixedI tried rebuilding the engine in the master branch but the result is still the same.
Before when creating PR # 177572, I rebuilt the engine and tested, everything was OK.
But it seems that there is some change that makes my PR fix no longer worked.
I will investigate the cause again.
letrungdo commentedon Nov 14, 2025
@gmackall This PR #178015 broke my fix, I tried revert the packages/flutter/lib/src/services/platform_views.dart file and everything worked as expected
