Approach to create Camera app
- The app uses the React useState hook to manage state variables.
- hasCameraPermission is a state variable to track camera permission status.
- camera is a state variable to hold the reference to the camera component.
- The app uses the Camera component from the ‘expo-camera’ library.
- When the “Take Picture” button is pressed, the takePicture function is called. The function captures a picture using the takePictureAsync method of the camera and sets the image URI in the state.
- If an image is captured (image state is not null), it is displayed along with a “Retake” button. The “Retake” button allows users to discard the captured image and go back to the camera preview.
