QUESTION
I want to show some data (from 1st screen to the 2nd second screen) from an array and it works well for the 1st time. But when I back to my previous screen and select another option then it shows present selected data containing previous data too. So I want to empty my array while I back to my 1st screen. How can i do it?
1st-screen code here.

QUESTION
i'm trying to create an app using React Native. I'm trying to make a drop down option that allow users to click, which will then be directed to another screen within the app.
I have tried using {DropDownItem} from "react-native-drop-down-item", and {Dropdown} from "react-native-material-dropdown", but these two don't seem to made for the function of a clickable contents within the dropdown.
Would appreciate any help with codes, thank you so much!
