React Native Slider | Tutorial for Beginners

React Native removed the Slider from core, so if you follow an old tutorial it just breaks. The fix is the community package, and in the video I wire it into a real to-do app so users can drag to set task priority, with emojis that update live as the slider moves.

It's a small feature, but it covers the pattern you'll reuse everywhere: bind a component to state, map a continuous value to discrete levels, update the UI in real time.

What's inside

• Install @react-native-community/slider with Expo
• Customize track colors and width for a cleaner look
• Track the slider value with useState and onValueChange
• Format the raw float into a readable display value
• Map slider positions to low, medium, and high priority
• Show dynamic emojis with a small helper function
