flutter_citizen_printer 0.0.6

Flutter plugin for Citizen label printer via USB and WiFi.

0.0.6

• BREAKING ENHANCEMENT: Made serial number reading optional in searchUsbPrinters() method
• New features:
  • Added optional includeSerialNumbers parameter to searchUsbPrinters() (defaults to false)
  • Enhanced performance by avoiding permission requests when serial numbers are not needed
  • Maintained backward compatibility while providing opt-in serial number functionality
• Performance improvements:
  • Fast default behavior: USB search without serial numbers requires no permissions
  • Smart permission optimization: only requests USB permissions for CITIZEN devices when serial numbers are explicitly requested
  • Reduced user interruption by eliminating unnecessary permission dialogs
• Technical enhancements:
  • Improved asynchronous handling to support both fast and detailed USB searches
  • Enhanced code documentation and comments in English for international development
  • Better separation of concerns between basic device enumeration and detailed device information

0.0.5

• Enhanced USB Serial Number Support: Added asynchronous serial number reading for CITIZEN USB printers with optimized permission handling
• New features:
  • Asynchronous serial number retrieval for CITIZEN devices only (optimized to avoid unnecessary permission requests)
  • Sequential permission handling to prevent conflicts between multiple USB device access requests
  • Enhanced UsbPrinterInfo class with serialNumber field populated for CITIZEN devices
  • Improved error handling and logging for USB device management
• Performance optimizations:
  • Smart filtering: only requests permissions for devices with "CITIZEN" manufacturer name
  • Non-blocking USB search process that handles permission dialogs gracefully
  • Prevention of concurrent search operations to avoid conflicts
• Technical improvements:
  • All code comments translated to English for consistency
  • Enhanced BroadcastReceiver for handling both print and serial number permissions
  • Better state management for asynchronous operations

0.0.3

• Multiple USB printers support: Added ability to manage and print to multiple USB printers simultaneously.
• New features:
  • searchUsbPrinters() - Search for all connected USB printers
  • printImageUsbSpecific(deviceId, imageBytes) - Print to a specific USB printer by device ID
  • UsbPrinterInfo class to represent USB printer information (device ID, name, manufacturer, vendor/product IDs)
• Enhanced printer identification: Each USB printer is now uniquely identified by device ID
• Improved example app: Added UI to select and print to specific USB printers
