no its not this means i wanna to check if permission is granted or not .... because this block only run when user click on allow but if its already allowed then how can i check it ?

Yes, but the user also could revoke permissions again in the settings of the app...

I agree, to have a method which is able to check, if a permission has been granted would be nice to have... @ewpatton, what do you think?

Probably there is an extension available, which is able to do it?
