Documentation

V3

You're looking at the V3 version of VisionCamera, which features a full rewrite on the Android codebase and a huge refactor on the iOS codebase. If you encounter issues on V3, you can also downgrade to V2, which is still partially supported.

Example

function App() {
  const device = useCameraDevice('back')

  if (device == null) return <NoCameraErrorView />
  return (
    <Camera
      style={StyleSheet.absoluteFill}
      device={device}
      isActive={true}
    />
  )
}

See the example app
