React Native Expo Camera | Tutorial
Beto, August 4, 2023 · 8,407 views
Building a camera app feels intimidating until you do it once. With Expo Camera it comes down to permissions, a ref, and a few state variables. I build the full flow on a real device in the video: capture, flash, flip, retake, save.
What's inside
- Requesting camera and media library permissions on mount
- State for camera type, flash mode, and the captured image
- Capturing photos with takePictureAsync through a ref
- Toggling flash and switching front and back cameras
- Saving to the gallery with MediaLibrary and confirming with alerts
- A retake-or-save flow like a real camera app
