I am using flutter_ble_peripheral in flutter_foreground_task. It worked 1.1.1, but I have the following problem since 1.2.0.

I think The same issue is also occurring when using activityBinding!! There was a function that used activityBinding!! in 1.1.1, but there was no problem using start(),stop(),isAdvertising.
