React Native TypeScript error: Property 'calcYOffset' does not exist on type 'ScrollView'

I have a ref of a ScrollView:

const myRef = React.useRef<null | ScrollView>(null);<ScrollView  onScroll={() => {    childRef.current?.calcYOffset();  }}

However calcYOffset gives me this error:

TS2339: Property 'calcYOffset' does not exist on type 'ScrollView'.
