MLKit Barcode

The mlkit-barcode plugin provides seamless integration with Google's ML Kit Barcode Scanning API, allowing you to detect and decoding barcodes in real-time.

Installation

implementation("io.github.l2hyunwoo:camera-plugin-mlkit-barcode:1.0.0")

Usage

1. Create the Plugin

You can configure the scanner to detect specific formats for better performance.

// Scan all formats (default)
val scanner = remember { BarcodeScanner() }

// Or specify formats (e.g., only QR codes)
// Note: Constructor parameters for formats are coming in next version

2. Register with CameraController

Using DSL:

val controller = rememberCameraController {
    plugins {
        +scanner
    }
}

3. Observe Results

The plugin exposes a barcodes StateFlow that emits a list of detected barcodes.

LaunchedEffect(scanner) {
    scanner.barcodes.collect { barcodes ->
        barcodes.forEach { barcode ->
            println("Scanned: ${barcode.displayValue}")
        }
    }
}
