[mrwill84]

Hi Guys
this's the greatest sqlite lib I used in flutter . much appreciated for hard work.
I'm not sure and search all the possible on internal ,can't find the proper solution .
I'm perparing to do a database viewer in iOS, and I want to create a db file out of application . I tried to open db file ( in doc or out of doc ) it works likes charming .
but can't create in my real iOS phone ( simulation also work well )
any suggestion here ? any ideas I loves ?

You seem to have a null check error here (hard to say without seeing the code):
