I am getting this error
Error: Function components cannot have string refs. We recommend using useRef() instead. Learn more about using refs safely here: https://reactjs.org/link/strict-mode-string-ref
This error is located at: in RCTView (created by View) in View (created by App) in App (created by withDevTools(App)) in withDevTools(App) in RCTView (created by View) in View (created by AppContainer) in RCTView (created by View) in View (created by AppContainer) in AppContainer in main(RootComponent)
i want to know where i have mistaken or is there any other steps need to be followed.
Try this:
const sheetRef = useRef<BottomSheet | null>(null);
Or
const sheetRef = useRef<BottomSheet>();
