Converting Lat Lng to Address displays null in flutter? - flutter

Question

The function displays the location Location NULL. I am getting the current location in superinit state and want to display the address from the placemark as text in the size box widget.
The function I have created to convert latitude and longitude to address getAdd() is also initialized in the initial state but when I call placemark in the text widget it displays null.
I have entered dummy values as well and tried printing in debug console which says.
