Flutter Web Tracker does not load with Flutter 3.x

1

After upgrading my Flutter environment to 3.0.x the Web Tracker does not load correctly. The error reported in the Chrome(v 102) console is below. I see the same problem in Firefox & Safari and I’ve also tried versions 3.2.3 - 3.4.0 of the JS SDK.

I can reproduce this problem in my company’s application as well as the example app.

I’ve also verified that I can downgrade to Flutter 2.10.x and both apps work correctly.

Anyone else having this problem?
Thanks

Hi @j.racz, I was able to reproduce the same issue when upgrading Flutter to version 3. We will address this and issue a patch release of the tracker. I will keep you updated in this thread.

Thanks for reporting!
