@andrey-ushakov I am facing the same issue. Can anyone tell me what to do with this issue?

I/flutter (12056): Something really unknown: Null check operator used on a null value

When I go to load final profile = await CapabilityProfile.load();
It never finds the capabilities.json file
If you could help me with this problem I would appreciate it, I have tried to add it as assets in the project but it does not work.
Thanks
