Android only issue with pinch zooming/rotating #957

Open lukey78 opened 3 years ago

lukey78 commented 3 years ago

In my App Peaks! (https://play.google.com/store/apps/details?id=com.adventurelog.peaks) I'm embedding a flutter_inappwebview to display a 3D world based on CesiumJs.

Everything works great except for the pinch-to-zoom and pinch-rotate two finger gestures. They both do well on iOs, but not on Android.

The behaviour is that it works "a little" each time. The zooming is not intuitive. It seems the evens are captured and stopped somewhere, and only a small part of the zoom event reaches CesiumJs inside the webview. Sometimes this also applies to simple horizontal/vertical move gestures.

Can anyone point me into the right direction? I already tried with/without hybrid composition, and setting/unsetting zoom options.

I've uploaded a demonstration of the problem inside an emulator view: https://youtu.be/AGE_H3_66EU

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!
