path_provider may be problem

I tried to add path_provider 2.1.4 but flutterflow says we automatically added 2.1.3 version so you should remove dependency.

But the problem seems that the code stucks when it needs to use getTemporaryDirectory as output directory of pdf file created.

Error:

The function 'getTemporaryDirectory' isn't defined.

Try importing the library that defines 'getTemporaryDirectory', correcting the name to the name of an existing function, or defining a function named 'getTemporaryDirectory'.dartundefined_function
