Detect scroll inside iframe in InAppWebView #2092

Description

I'm using the onScrollChanged callback:

onScrollChanged: (controller, x, y) {
  final pxRatio = MediaQuery.of(context).devicePixelRatio;
  context.read<AppData>().scroll.add(
    ScrollData(
      scrollProgress: y / pxRatio,
      timestamp: DateTime.now(),
    ),
  );
}

But InAppWebView only defines the main scroll. That is, in applications such as Miro or Figma, the scroll will not be detected. Also, this will not work, for example, in the burger menu of the site if it has a scroll. How can I detect scrolls in such cases?

Expected behavior: Scroll detected in iframes and context.read<AppData>().scroll != [];

Current behavior: Scroll not detected context.read<AppData>().scroll = [];

Steps to reproduce

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!
