Thanks a lot :)

I will take look in the next few days.
Could you provide the output of flutter doctor -v? By doing so I will know your environment which hopefully helps to find the bug quicker.

[ueman]

Okay, so I see you are using the Flutter beta channel. This package isn't testet on it and isn't yet migrated to nullsafety. So that could already be the problem. I'll have to test that.

Have you tried building it on the stable channel?

Hi @ueman,

Thank you again for quick reply,
Yes I did try on stable,
