Generate a Ticket

Simple Ticket with Styles:

Ticket testTicket() {
  final Ticket ticket = Ticket(PaperSize.mm80);

  ticket.text(
      'Regular: aA bB cC dD eE fF gG hH iI jJ kK lL mM nN oO pP qQ rR sS tT uU vV wW xX yY zZ');
  ticket.text('Special 1: àÀ èÈ éÉ ûÛ üÜ çÇ ôÔ',
      styles: PosStyles(codeTable: PosCodeTable.westEur));
  ticket.text('Special 2: blåbærgrød',
      styles: PosStyles(codeTable: PosCodeTable.westEur));

  ticket.text('Bold text', styles: PosStyles(bold: true));
  ticket.text('Reverse text', styles: PosStyles(reverse: true));
  ticket.text('Underlined text',
      styles: PosStyles(underline: true), linesAfter: 1);
  ticket.text('Align left', styles: PosStyles(align: PosAlign.left));
  ticket.text('Align center', styles: PosStyles(align: PosAlign.center));
  ticket.text('Align right',
      styles: PosStyles(align: PosAlign.right), linesAfter: 1);

  ticket.text('Text size 200%',
      styles: PosStyles(
        height: PosTextSize.size2,
        width: PosTextSize.size2,
      ));

  ticket.feed(2);
  ticket.cut();
  return ticket;
}

Print a Ticket

PrinterBluetoothManager printerManager = PrinterBluetoothManager();

printerManager.scanResults.listen((printers) async {
  // store found printers
});
printerManager.startScan(Duration(seconds: 4));

// ...

printerManager.selectPrinter(printer);
final PosPrintResult res = await printerManager.printTicket(testTicket());

print('Print result: ${res.msg}');
