flutter_thermal_printer_windows 0.0.1

Bluetooth thermal printer support for Flutter on Windows. Discovery, pairing, connection, and ESC/POS receipt printing for POS applications.

0.0.1

• Initial release.
• Bluetooth printer discovery (scan, SPP filter).
• Pairing and connection management (pair, unpair, connect, disconnect).
• Connection state stream and diagnostics (getPrinterCapabilities, getPrinterStatus, getPairedPrinters).
• ESC/POS command generation (text, alignment, bold, underline, font size, image, barcode, QR, feed, cut).
• PrintEngine: receipt-to-ESC/POS conversion, job queue per printer, sendRawCommands.
• ThermalPrinterWindows main API (singleton): scanForPrinters, pairPrinter, unpairPrinter, getPairedPrinters, connect (optional printSampleOnSuccess), printConnectionSuccessSample, disconnect, getConnectionStateStream, printText, printReceipt, printRawBytes, getPrinterCapabilities, getPrinterStatus).
• Data models: BluetoothPrinter, Receipt, ReceiptItem, ReceiptSettings, PrinterCapabilities, PrinterStatus, PairingResult, ConnectionResult.
• Validation: Receipt and ReceiptSettings validation with ValidationException.
• Error hierarchy: ThermalPrinterException and subclasses with errorCode, cause, context; fromCode() mapping.
• Windows plugin: method channel and C++/WinRT Bluetooth implementation (MTA worker thread, SPP discovery, pairing, StreamSocket connection, raw byte send).
• Local status tracking (isPaired, connectionState) for Windows where native pairing status is unreliable.
• PlatformException → ThermalPrinterException mapping with user-friendly error messages.
• Production-oriented logging (errors only in release; verbose logs in debug builds).
