Changelog #

3.2.1 #

Smart Sync: Built offline telemetry database/queueing on native Android and iOS, featuring rolled file rotation, internet connectivity detection, and automated background upload with exponential retry backoff.
NFC Module: Implemented Near Field Communication (NFC) scan and NDEF tag writer on both platforms with foreground dispatch on Android and reader sessions on iOS.
Secure Storage: Developed AES-256 encrypted file and JSON storage using Android KeyStore and iOS Keychain.
Background Isolates: Added BackgroundIsolateWrapper to spawn low-priority background isolates for heavy CPU/computation operations.
Integration & Testing: Integrated all native and Dart parts of Phase 5, passing all 78 unit tests successfully.
Stability & Guards: Added isRunning checks to protect state-sensitive modules (Camera, Bluetooth) and wrapped native methods to throw clean typed HardwareExceptions.
GATT Enhancements: Implemented BLE device disconnect and GATT characteristic read APIs.
Developer Experience: Added NexoraSdk.initialize pre-warming, value equality/hashcodes on models, copyWith on options/configs, and readable toString overrides.
Advanced Features: Added migrateStorage migration engine, stream helpers (throttle, debounce, bufferCount), and retry helper (withRetry) with backoff.
Testing Gaps: Expanded test coverage with comprehensive module-specific tests and serialization tests, resulting in a 72-test suite passing at 100%.

Introduced utility module with EcoMode power-saver and proactive Thermal Safeguard crash prevention.
Built custom native option builders for Camera, Sensors, Bluetooth, Location, Biometrics, and Haptic feedback.
Refactored eager module initializers into lazy cached properties for zero startup overhead.
Designed advanced Speaker & Microphone controllers with input gain and output routing.
Fully verified with 21 unit tests.

Aligned local Android, iOS, example, and Dart metadata with the published Swift Package Manager-enabled release.
Refreshed example dependency locks for the current plugin version.

Improved default camera preview quality to 1280x720 while throttling native vision processing for speed.
Added camera quality presets, including Full HD, while keeping custom width and height support.
Made audio streaming lighter by disabling raw audio bytes by default and adding event interval control.
Hardened camera/audio model parsing for lightweight native events.
Improved BLE scan/connect/write failure reporting instead of always returning success.
Added native lifecycle cleanup for camera, audio, sensors, location, BLE, textures, and logging.
Removed unused raw camera module files and added publish ignore rules for generated artifacts.
Updated example Android and iOS identifiers to Nexora package IDs.
Registered web, macOS, Windows, and Linux with safe Dart fallback implementations.
Changed Android package/namespace from com.example.nexora_sdk to com.nexora.sdk.
