ble_peer_session library

Offline 1:1 peer sessions over BLE for Flutter.

Host/client model with invitation handshake and bidirectional messaging. See Peer for the main entry point.

Classes

BlePeerConfig: BLE P2P session configuration (service UUIDs and app identifier).
BlePeerUuidGenerator: Derives stable BLE UUIDs from appName so every install of the same app can find each other.
BluetoothPermissionsService: Bluetooth runtime permission checks (Android 12+).
Device
Logger: Logging contract for the BLE transport layer.
Peer: Entry point for offline BLE 1:1 peer sessions.
PeerClient: Client side of a 1:1 BLE peer session (discovers hosts and connects).
PeerClientImpl
PeerConnectionInfo: Snapshot of the active peer session.
PeerDisconnectInfo: Emitted when an established session ends for any reason.
PeerEndpoint
PeerHost: Host side of a 1:1 BLE peer session (advertises and accepts connections).
PeerHostImpl
PeerIdentity
PeerMessage: Wire envelope for session handshake and application payloads.
PeerMessageTypes: Reserved type values for the consent handshake between two peers.
PeerNearby: A nearby host discovered while scanning (friendly name for Device).
PeerSessionMessaging: High-level text/JSON helpers shared by PeerHost and PeerClient.
PeerUser: The local or remote player visible to your app (not a BLE/GATT concept).
SilentLogger: No-op logger used when Peer.create is called without an explicit Logger.

PeerAdapterStatus: System Bluetooth adapter state exposed to applications.
PeerConnectionPhase: High-level connection lifecycle exposed to applications.
PeerDisconnectReason: Why an established BLE peer session ended.
PeerErrorCode: Classifies recoverable and diagnostic BLE peer session failures.
