[konnic]

Same for me. From my analysis the origin of this issue lies with the forked package flutter_inappwebview_quill, which uses the exact same package name as the original flutter_inappwebview package.

@sarbagyastha could you explain why the dependency to flutter_inappwebview_quill was introduced? Would it also be possible to rely on flutter_inappwebview instead?

[konnic]

@sarbagyastha just saw that you're not the official author of youtube_player_flutter_quill, but that your package was forked as well. Would you know by any chance who the author of the fork is?

Update: nvm, found it: https://github.com/jisjoemathew91/youtube_player_flutter_quill

[gi-nam-dev]

I see. I took down the quill package. Can I use them both now?

I don't understand what you mean with "Can I use them both now?". I think you need to open up an issue in this repo: https://github.com/jisjoemathew91/youtube_player_flutter_quill
