Compare to webview_flutter, inappwebview is significant frame dropped while page scrolling

Compare using the example in each plugin on a device with 60Hz screen.
This issue might happened since Flutter 3.0.

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!

May be related to #1335? Does it happen on iOS?

I am tested on Android and iOS with 60Hz, i think it's fine on iOS compare to Safari.
I don't think so that the two issues are related because the mechanics are completely different in Android and iOS.

Based on previous testing that compared with plugin webview_flutter, I think we need to do some changes in inappwebview.
I am trying to do more testing on old version of inappwebview and Flutter, and will add more info later.
