Crash in Dart Compiler share_plus-8.0.2/lib/src/share_plus_web.dart:316:20 about sdk

Thanks @butterbrain! To help us investigate, do you happen to have a small example of code you can share that will help us reproduce the issue?

From the error message, it seems the compiler failed on some constructor of a ShareData declaration. Could you share what that declaration looks like?

sorry, I missed that you shared the location of the issue in the title.

Here is it's declaration:
https://github.com/fluttercommunity/plus_plugins/blob/58596acafa27ee258925e3a8a15493d13ad94995/packages/share_plus/share_plus/lib/src/share_plus_web.dart#L316

And where it's used: https://github.com/fluttercommunity/plus_plugins/blob/58596acafa27ee258925e3a8a15493d13ad94995/packages/share_plus/share_plus/lib/src/share_plus_web.dart#L232

OK, I isolated the issue and I can confirm this is now fixed.

There was an issue with the Dart stable 3.3.0 SDK, which was then fixed in a patch release with Dart 3.3.1. The issue was that object-literal JS-interop constructors (such SharedData.files here) didn't work in dart2js unless the enclosing library had a @JS() annotation. Instead of reporting an error, the compiler crashed! I believe it was because this used to be required in the old interop, but we decided it shouldn't be required anymore, but then one part of the compiled wasn't adjusted to properly understand code without the annotation. More details available in the issue describing the 3.3.1 cherry-pick:
#55057

Since this is now released in the stable channel, most likely the only thing you need to do is to update to the latest stable release of Dart and Flutter.
