NfcReadManager

internal actual class NfcReadManager(config: NfcConfig) : NfcAdapter.ReaderCallback(source)

Android implementation of NfcReadManager. This class handles NFC tag scanning using the Android NFC Adapter in Reader Mode.

internal expect class NfcReadManager(config: NfcConfig)(source)

Manager class for handling NFC reading operations.

This is an expected class with platform-specific implementations for Android and iOS. It manages the NFC scanning process, provides results via a StateFlow, and handles the UI (like bottom sheets on Android or native dialogs on iOS).

internal actual class NfcReadManager(config: NfcConfig) : NSObject, NFCTagReaderSessionDelegateProtocol(source)

iOS implementation of NfcReadManager. This class handles NFC tag scanning using CoreNFC's NFCTagReaderSession.

RegisterManager

@Composable

actual fun RegisterManager()

A Composable function that registers the manager with the current Activity and Context. It handles the lifecycle of the NFC adapter and displays the scan bottom sheet when active.

@Composable

expect fun RegisterManager()

A Composable function that registers the manager within the Compose UI hierarchy. This is typically used to handle lifecycle events and show scanning-related UI components.

@Composable

actual fun RegisterManager()

A Composable function that registers the manager. On iOS, this is currently a no-op as the scanning UI is handled by the system.

respondsToSelector

expect open override fun respondsToSelector(aSelector: COpaquePointer?): Boolean

startScanning

actual fun startScanning()

Starts the NFC scanning process. Checks if the NFC adapter is available and enabled, then enables Reader Mode.

expect fun startScanning()

Starts the NFC scanning process.

actual fun startScanning()

Starts the NFC scanning process by initiating an NFCTagReaderSession. Checks if NFC reading is available on the device before starting.

stopScanning

actual fun stopScanning()

Stops the NFC scanning process and disables Reader Mode.

expect fun stopScanning()

Stops the NFC scanning process.

actual fun stopScanning()

Stops the NFC scanning process and invalidates the current session.

superclass

expect open override fun superclass(): ObjCClass?

tagReaderSession

open override fun tagReaderSession(session: NFCTagReaderSession, didDetectTags: List<*>)

Invoked when one or more NFC tags are detected.

open override fun tagReaderSession(session: NFCTagReaderSession, didInvalidateWithError: NSError)

Invoked when the session is invalidated, either by the user or due to an error.

tagReaderSessionDidBecomeActive

open override fun tagReaderSessionDidBecomeActive(session: NFCTagReaderSession)
