flutter_activity_recognition is not working when phone is locked and screen is off

[lakhanrathi1]

I am using flutter_foreground_task to get activity in backgroud and foreground
It work perfectly when phone is on and app is killed also.
but when phone is locked and screen is off it is not working even with flutter_foreground_task and as soon as unlocked my phone it again start working

I want to get user activity update even if phone is locked and screen is off (for example phone is in pocket and user is running)

any solution on this?
