azure_iot_hub 0.1.0-dev.1

Unofficial native Dart device SDK for Azure IoT Hub with MQTT/TLS, WebSockets, SAS/X.509 authentication, telemetry, twins, direct methods, C2D messages, retries and cancellation.

0.1.0-dev.1

• Add an experimental DeviceClient API for native Dart runtimes, following the pinned C# SDK's behaviour for supported features.
• Support SAS authentication with shared keys, supplied tokens and asynchronous token providers, including credential caching and refresh on reconnect.
• Support X.509 authentication over MQTT/TLS and secure WebSockets with a prepared Dart SecurityContext; WebSockets require explicit TLS renegotiation opt-in.
• Support MQTT over TLS and secure WebSockets.
• Send QoS 1 telemetry with application properties and supported message metadata.
• Retrieve twin properties, update reported properties and receive desired-property patches, restoring subscriptions after reconnect.
• Add SDK-owned cancellation tokens, finite operation deadlines, transient retries, bounded pending work and explicit delivery uncertainty.
• Add connection-status callbacks for connection, recovery and shutdown.
• Handle direct methods with named/default async callbacks, bounded incoming work, response retries and subscription recovery.
• Receive cloud-to-device messages by polling or callback, with message properties, explicit ordered completion and bounded incoming storage.
• Include adapted C# tests, deterministic lifecycle tests and opt-in IoT Hub tests.
