A Flutter plugin for Voice User Interface (VUI) using Android Accessibility Service. Provides on-device speech recognition with rule-based NLP for Indonesian language, enabling voice-controlled naviga [...]

1.0.2

• Engine priority reversed: Default Android speech engine is now tried first, with Google Speech Services as fallback
• Fixed voice capture error on Oppo/ColorOS: EXTRA_PREFER_OFFLINE is now only applied to Google engine — default engines often lack offline Indonesian models and would immediately error
• Improved engine fallback: When the default engine fails after max retries, the plugin automatically switches to Google engine instead of reporting an error

1.0.1

• Simplified help commands: unified 4 global commands shown on all screens
• Help overlay no longer changes per screen context

1.0.0

• Stable release 🎉
• Device compatibility improvements:
  • Google Speech engine auto-binding for Samsung/OEM devices with automatic fallback to default engine if Google engine is unresponsive (3-second ready-timeout)
  • Volume-down double-press as alternative trigger for devices using gesture navigation (where accessibility button is unavailable)
  • Accessibility button availability detection with auto-fallback logging
  • Diagnostic broadcast on service connect (device info, speech engine status, button availability)
• Enhanced NLP patterns:
  • Flexible verb variants: tambahkan, tambahin, masukkan, isikan, jualkan, bikin
  • Inverted word order support: "tambahkan 5 stok chocolatos" alongside "tambah stok chocolatos 5"
  • Extended stop→stok normalization for new verb variants
  • Reordered regex patterns to prevent conflicts between specific and generic matches
• Bug fixes:
  • Product-not-found validation before navigation (shows error in speech overlay instead of navigating to empty screen)
  • errorMessage support in VuiSpeechOverlay for contextual error feedback
  • Improved isActive state detection in speech overlay
