1.0.0+7 - 2025-01-09

Changed

• Architecture: Integrated swip-core directly into the SDK
  • Removed external swip_core package dependency
  • Core implementation now lives in lib/src/core/ (19 files)
  • This simplifies dependency management and ensures version consistency
  • All swip_core types are now exported from the main SDK package
• Dependencies: Updated package dependencies
  • synheart_wear: ^0.2.2 (was 0.1.2)
  • synheart_emotion: ^0.3.0 (was 0.2.0)
  • Added flutter_onnxruntime: ^1.5.2 (required for integrated core)
  • Removed external swip_core path dependency
• Model Files: Updated to use nozipmap ONNX model format
  • Added ExtraTrees_60_5_nozipmap.onnx and metadata to SDK assets
  • Model now uses binary classification (Baseline vs Stress) instead of 3-class
  • Model ID: extratrees_chest_ecg_w60s5_binary_v1_0

Fixed

• ONNX Inference Error: Fixed RangeError (length): Invalid value: Only valid value is 0: 1 error in emotion inference
  • Updated to use ExtraTrees_60_5_nozipmap.onnx model (same as synheart-poc-dart)
  • The nozipmap model outputs probabilities directly without ZipMap wrapper, fixing output parsing issues
  • Model ID is now automatically read from loaded model's metadata for consistency

Added

• Example App: Complete example app refactoring
  • Added SwipController demonstrating proper SDK integration
  • New modular UI structure with HomePage and SwipPage
  • Shows real-time SWIP scores and emotions
  • Includes session management and history
  • Demonstrates storage integration with SQLite
  • Aligned Android configuration with SDK best practices

Improved

• Model loading now uses model's own metadata for modelId, ensuring consistency
• Better code organization with integrated core implementation

1.0.0+6 - 2025-01-09

Fixed

• ONNX Inference Error: Fixed RangeError (length): Invalid value: Only valid value is 0: 1 error in emotion inference
  • Updated to use ExtraTrees_60_5_nozipmap.onnx model (same as synheart-poc-dart)
  • The nozipmap model outputs probabilities directly without ZipMap wrapper, fixing output parsing issues
  • Model ID is now automatically read from loaded model's metadata for consistency
• Permission Handling: Fixed redundant permission requests that prevented Health Connect UI from opening correctly on Android
• Initialization Flow: Improved SDK initialization to follow best practices from synheart-poc-dart
  • Now calls initialize() first (matching synheart-poc-dart pattern), then checks for existing permissions
  • Gracefully handles cases where Health Connect is not yet installed
  • Re-initializes wearable SDK after permissions are granted
• Android 14+ Compatibility: Fixed "Permission launcher not found" error by requiring MainActivity to extend FlutterFragmentActivity instead of FlutterActivity (see example app)

Changed

• Model Files: Updated to use nozipmap ONNX model format
  • Added ExtraTrees_60_5_nozipmap.onnx and metadata to SDK assets
  • Model now uses binary classification (Baseline vs Stress) instead of 3-class
  • Model ID: extratrees_chest_ecg_w60s5_binary_v1_0
• Permission Request Pattern: Updated to explicitly request platform-specific permissions
  • Android: Requests heartRate, heartRateVariability (RMSSD), steps, calories (excludes distance as Health Connect doesn't support it)
  • iOS: Requests all types including distance (HealthKit supports all)
• Error Handling: Better error handling for Health Connect availability issues
  • SDK can now work even if Health Connect is installed after initial initialization attempt

Added

• Example App: Added SwipController to example app demonstrating proper SDK integration
  • Shows real-time SWIP scores and emotions
  • Includes session management and history
  • Demonstrates storage integration

Improved

• Health Connect permissions screen now opens correctly when permissions are requested
• Removed duplicate permission requests that were causing initialization issues
• Better state management for wearable SDK initialization
• Model loading now uses model's own metadata for modelId, ensuring consistency
