Architecture

The project follows a straightforward architecture using Jetpack Compose and CameraX:

• MainActivity: The main entry point, handling camera initialization and managing the UI.
• Composable Functions: Individual composable functions are used to build the UI, such as CameraPreview, QRCodeResult, and CameraPermission.
• QRCodeAnalyzer: This class processes each camera frame to detect and decode QR codes using ML Kit.
• State Management: Uses Compose's remember and mutableStateOf for managing UI state and QR code results.

Technologies Used

• Jetpack Compose: For building the UI in a declarative manner.
• CameraX: To access and control the camera.
• ML Kit: For barcode scanning and QR code detection.
• Accompanist: For managing permissions in Compose.
• Kotlin: The programming language used for building the application.
