1.0.1+stable

Maintenance Release

• Updated flutter_lints to ^6.0.0
• Added MIT license
• Fixed repository URLs in pubspec.yaml
• Package cleanup for pub.dev publication

1.0.0+stable

Stable Release - Production Ready

• Connection Status Monitoring

  • Real-time connection status stream via connectionStatusStream
  • Automatic connection loss detection and recovery
  • Visual connection status indicators in example app

• Automatic Reconnection (HOLD Mode)

  • Automatic reconnection every 10 seconds when connection is lost
  • MAC address-based reconnection for faster pairing
  • Smart reconnection only when device was previously connected

• Enhanced Connection Methods

  • scanAndConnectFirst() - Scan and connect to first device found
  • connectByMacAddress(String macAddress) - Direct connection by MAC address
  • Improved connection reliability and error handling

• Example App Improvements

  • Integrated mode selector with connection status display
  • Real-time Bluetooth connection indicator (green/red)
  • Automatic reconnection status messages
  • Enhanced user experience with visual feedback

• Bug Fixes

  • Fixed HOLD mode implementation - no longer activates sensor notifications
  • Resolved overflow issues in example app with scrollable interface
  • Improved error handling and user feedback

• Dependencies Updated

  • flutter_blue_plus: ^1.35.5 (was ^1.32.12)
  • permission_handler: ^12.0.1 (was ^11.3.1)

Breaking Changes

• HOLD mode now works correctly by reading sensor manually instead of using notifications
• Connection status monitoring requires listening to connectionStatusStream
