Add the dependency to your commonMain sourceSet (KMP) / Android dependencies (android only):

Or, for your libs.versions.toml:

[versions]
easyqrscan = "0.1.5"
[libraries]
easyqrscan = { module = "io.github.kalinjul.easyqrscan:scanner", version.ref = "easyqrscan" }

Camera Permissions

Include this at root level in your AndroidManifest.xml:

<uses-feature android:name="android.hardware.camera"/>
<uses-feature android:name="android.hardware.camera.autofocus"/>
<uses-permission android:name="android.permission.CAMERA"/>

Add this key to the Info.plist in your xcode project: NSCameraUsageDescription and provide a description as value

Compose UI

// basic permission handling included:
ScannerWithPermissions(onScanned = { println(it); true }, types = listOf(CodeType.QR))

// or, if you handle permissions yourself:
