Version

8.9.0

Steps to Reproduce

I don't have a clue on how to reproduce since I cannot identify the error at all

Expected Result

I should be able to see the source code for my own code at least. You can see in the stacktrace that there are some part that matches my flutter application.

It's only this specific issue that causing troubles, other issues are showing stacktraces correctly

Actual Result

I can't see anything aside from the exception message

Are you willing to submit a PR?

None

hey can you provide more info on your setup, which packages do you use? is this somehow related to wasm? I'm confused why there's native code in a flutter web app

I've tweaked my index.html to include a loader + amplitude SDK as you can see below

The app can be used in kiosk mode so behaviour changes depending on whether or not we're on an android device, for that I rely on kIsWeb and Platform.isAndroid

Aside from that, the rest is very standard

  <link rel="stylesheet" href="loader.css" />

    <div class="loader">

  </div>

  <script src="flutter_bootstrap.js" async></script>

</html>

Loader is then hidden with :

void hideLoader() {
  if (kIsWeb && !loaderHidden) {
    (html.window.document.getElementsByClassName('loader-container').first
            as html.Element)
        .classes
        .add('hide');
    loaderHidden = true;
  }
}

Also, html library is imported as :

import 'package:medami_patient/src/utils/fake_html.dart'
    if (dart.library.html) 'dart:html' as html;

with fake_html.dart just being a dummy to allow code to compile on android

// This package is intended to provide a cross platform alternative to import dart:html

late dynamic window;
typedef Element = dynamic;

do you mind sending over the event to my email [email protected]

from what I can tell though this is issue starts in the SDK, unparsed usually means we could not parse a stacktrace on the SDK level. It could be in a format that we do not expect for example so we don't handle it. from the looks of it the unparsed frame comes from here
