ble_peer_session 0.2.0

Offline BLE peer-to-peer sessions for Flutter — discovery, consent handshake, and bidirectional messaging.

0.2.0

• Breaking: new public API — Peer, PeerHost, PeerClient, PeerMessage, PeerException, PeerErrorCode, PeerConnectionPhase, PeerAdapterStatus.
• Breaking: removed exports of TransportFacade, TransportSession*, TransportSessionState, session message classes, and Bluetooth*Exception.
• Unified errors into PeerException with PeerErrorCode.
• Adapter status via Peer.adapterStatusStream (no auto-enable Bluetooth).
• Documentation: mental model diagrams, connection/message flow, ERROR_CODES.md, MIGRATION.md.
• 1:1 sessions only; second central rejected at link layer.

0.1.2

• Fixed role switching in BleTransportFacadeImpl: skip disconnect() when the active session is uninitialized, preventing crashes on first startClientTransportSession / startServerTransportSession.
• Added state-aware disconnect() for client and server sessions (discovery, awaiting decision, connected).
• Added BleLinkReadiness to verify Bluetooth permissions and powered-on state before discovery/advertising.
• Added BluetoothUnsupportedException, BluetoothPermissionsDeniedException, and BluetoothPeripheralUnavailableException.
• Added tests for facade role switching.

0.1.1

• Removed unused dependencies (json_annotation, build_runner, json_serializable).
• Updated flutter_blue_plus and permission_handler.

0.1.0

• Initial release: BLE P2P session transport for Flutter.
• Discovery, invitation/acceptance handshake, bidirectional messaging.
• PeerMessage envelope for app-level payloads.
• BlePeerSessionModule factory and Bluetooth permission/state helpers.
