Hi @anilcngz, I cannot reproduce this issue with your provided code snippet on Flutter v3.3.3. It seems like an exception thrown by older Flutter versions.
Could you also post your flutter doctor -v?

Hi @whiplashoo , was this helpful? Please let me know if there is anything I can provide.
I can't reproduce this either with the example app or with your code snippet (with Flutter v3.3.4 and macos_ui v1.7.6). @GroovinChip can you have a look as well?

I'll give it a shot, yeah.
This is already fixed with https://github.com/GroovinChip/macos_ui/pull/300 - but not yet published as 1.7.6 on pub.dev.
