RangeError (index): Invalid value: Not in inclusive range (iOS)

[Hassanmohsaid]

Whenever I scroll to the top of the country list an exception always happens in iOS which is:

RangeError (index): Invalid value: Not in inclusive range 0..241: -3

I traced the code and found that the problem is in selection_list.dart line 305:

String? countryName = countries.elementAt(scrollPosition).name;

when scrollPosition is a negative number.

Fix:

Change the condition in line 304 to:

if (scrollPosition < countries.length && scrollPosition >= 0)
