Scrolling list on IOS is too slow sometimes hang

[FatmaMahmoud698]

DropDownPicker is not scrolling fine in IOS but working fine in android I found that problem is I use DropDownPicker inside modal if I use it in any other place working fine

<DropDownPicker
        items={AllMaterial}
        defaultValue={showProduct.material ? showProduct.material.value : null}
        containerStyle={{ height: 30, marginTop: 7 }}
        style={{
               borderColor: 'rgba(0, 0, 0, 1)',
               borderRadius: 0,
               backgroundColor: 'rgba(237, 237, 237, 1)'
          }}
       scrollViewProps={{
          persistentScrollbar: true
         }}
       labelStyle={{
           fontSize: 9.17,
            fontFamily: "proximaNovaBold",
            lineHeight: 12.19,
            textAlign: 'left',
            color: 'rgba(0, 0, 0, 1)',
        }}
      arrowStyle={{ margin: -8 }}
     dropDownStyle={{ backgroundColor: 'white', height: 120 * heightRate }}
      onChangeItem={item => setChoosenMaterial(item)}
/>

I can confirm this on Android as well. I'm using the listMode={'MODAL'}. It makes the application unresponsive for very long time.
