    borderRadius: 25, backgroundColor: colorConstants.ONE_APP_COLOR, justifyContent: 'center',

Answer 1

Just use this type of structure:

<View>
   <ScrollView>
   </ScrollView>
   <View>
   </View>
</View>

Your scroll view will have different height, based on number of items, it is an overhead to keep the View in the ScrollView , and probably you will have a lot of bugs and weird behaviors..
