country_state_picker's Issues

Selection of different Country Twice Error

I installed this package in my project, when I selected country for the first time there was no issue, but when I tried selecting it again this is the error I got in the state dropdown menu. If you select a country, and then you select a state, now try to select a different country without leaving the current screen
