2 weeks ago Note that I used this PR to get WebView to work on web: https://github.com/flutter/packages/pull/6792 as well as this branch to add the credentialless attribute: https://github.com/ThomasAunvik/flutter-packages/tree/wasmcredentialless

2 weeks ago Further testing shows that the error also happens on other simple HTML websites, so maybe it isn't related to some Godot specific functionality (like WebGL). I was however able to load pages at some point, so I am a bit confused about what causes it to work. It is however super easy to reproduce the error as seen in the example code.

2 weeks ago @uldall have you tried building & running with the -O1 optimization flag (the default -O4 is very aggressive and can sometimes make errors appear much later and therefore in seemingly unrelated places)?

2 weeks ago @mkustermann I tried this now: $ flutter build web --wasm --no-strip-wasm -O1 (And without the --no-strip-wasm). Unfortunately it didn't make a difference.

If using -O1 doesn't change the error and the error happens in skwasm.wasm then maybe the issue is in flutter engine /cc @eyebrowsoffire

2 weeks ago I don't think this is limited to Godot game. I have my website migrated to wasm and it has carousel. Swiping on carousel for a longer time also created this issue:
main.dart.js:3304 Uncaught RuntimeError: memory access out of bounds at canvaskit.wasm:0x3abfc at canvaskit.wasm:0x29150 at Tb.save (canvaskit.js:115:52) at Gv.d6 (main.dart.js:26771:53) at B_.j6 (main.dart.js:26595:3) at KO.jU (main.dart.js:26486:28) at a1L.$0 (main.dart.js:26727:18) at Object.axo (main.dart.js:1160:18) at a1I.aj5 (main.dart.js:26715:3) at main.dart.js:27070:27
Steps to reproduce
WebViewWidgetwidget. For example this game.flutter build web --wasm.Note that a fix for webview_flutter_web is added to be able to use
WebViewWidgetwith wasm.Expected results
The game is shown like it is when not using --wasm:
Actual results
The error is shown and the Godot game is not loaded:
