React Native SegmentedControl: How can I use Typescript to type case the onChange "event"?

How can I use Typescript to type case the onChange "event"?

I've tried using (event: NativeEvent) as onChange={(event: NativeEvent) => setSegmentIndex(event.nativeEvent.selectedSegmentIndex)}, but no luck.

SegmentedControl.tsx

<SegmentedControl  values={['Active', 'Expired']}  selectedIndex={segmentIndex}  onChange={(event) => setSegmentIndex(event.nativeEvent.selectedSegmentIndex)}/>
