Requirements

Requirement	Version
Flutter	>= 3.35.0
Dart SDK	>= 3.9.0 < 4.0.0
Android	`minSdk 24`, `compileSdk 36+`
iOS	15.0+

Android setup

The plugin merges these into the host manifest, so you normally add nothing:

<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.BLUETOOTH_SCAN" />
<uses-permission android:name="android.permission.BLUETOOTH_CONNECT" />
<uses-permission
    android:name="android.permission.NEARBY_WIFI_DEVICES"
    android:usesPermissionFlags="neverForLocation" />
<uses-permission android:name="android.hardware.nfc" />
<uses-permission android:name="android.permission.POST_NOTIFICATIONS" />
<uses-permission android:name="android.permission.FOREGROUND_SERVICE_MICROPHONE" />

:::warning Android 14+ (API 34+) throws SecurityException at service start unless the microphone foreground service is declared. The plugin ships RtcLinkForegroundService for exactly this case. :::

iOS setup

Usage strings cannot be injected by the plugin — add every one you use to ios/Runner/Info.plist:

<key>NSCameraUsageDescription</key>
<string>Camera access is required to publish video.</string>
<key>NSMicrophoneUsageDescription</key>
<string>Microphone access is required to publish audio.</string>
<key>NSBluetoothAlwaysUsageDescription</key>
<string>Bluetooth is used to provision and update devices.</string>
<key>NSLocalNetworkUsageDescription</key>
<string>Local network access is used to discover devices.</string>
<key>NFCReaderUsageDescription</key>
<string>NFC is used for tap-to-provision.</string>
<key>UIBackgroundModes</key>
<array>
  <string>audio</string>
</array>

NFC additionally requires the entitlement com.apple.developer.nfc.readersession.formats (paid account, explicit App ID).
