react-native-searchable-dropdown | Searchable Dropdown to help you search with in the list | Menu library

I using react-native-searchable-dropdown library , but if user write string with its not in item array I receive white screen. How I can add no result text (or its best option button who create missing option)?

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.

I want to use SearchableDropdown from react-native-searchable-dropdown as adrop down select with auto completion. The event onItemSelect is supposed to be fired when select an element from dropdown list. But it does not trigger so.

I'm new to React Native and Javascript, but I cannot find anything online to help me with this problem that I am having.

My "macSong" functions if statements never pass and I'm unsure as to why, I feel like the logic behind the code is sound, yet my console is still outputting "Selected Item is Unknown" because all of the if else statements are "not true" when at least one of them should be true if the dropdown menu has been used before pressing the button. My macSong function is just above my Stylesheet, at the bottom of my code.

If anyone can help me that would be amazing, thank you in advance and be sure to let me know if you need any more information to help you answer my question!

Here is my current app.js file. I would like for the button to "know" which dropdown menu item is selected, and then pick a random song from a list and write that song name on the screen.

Currently, no matter which "mood" you have selected, it will output only "happy song" names in the console.

I believe my error is somewhere in my If/If Else statements, but after a few hours of debugging/googling, I could not find what the problem was.

Basically, I need a function to call onPress of my button, and in that function, I need it to determine which dropdown is selected, and only output a single, random, song from that "mood" of songs. However, my current function, "macSong" will always output a "happy" song, even if the dropdown menu has something else selected.

If anything about my question is confusing, please write a comment below and let me know what I need to elaborate on, Thanks!
