File missing and other not in correct folder

[Ros4111]

I have been using fluter_quill without problem until flutter 2.8.1 with another libraries:
flutter_quill: ^2.3.0
flutter_markdown: ^0.6.8
delta_markdown: ^0.3.0

I want to move to flutter 2.10 and before I tried to update this libraries to:
flutter_quill: ^3.9.4
flutter_markdown: ^0.6.9
delta_markdown: ^0.4.0
but when I try to compile with flutter (2.8.1 or 2.10) /lib/models/documents/nodes/embed.dart file is missing.
Other files are in lib\models\documents but flutter look for them in lib\src\models\documents\ "scr" is the difference

Thanks for you work.
