Usage guidance

Give controls a visible label or an accessible name, and verify keyboard interaction. See Accessibility.
For controlled inputs, update the value from the callback shown in the props table. Keep application state in your component or form library.
These previews run in the browser. Check React Native setup for platform requirements and differences.
