printText method

Future<String?> printText(String textData, { String x = '0', String y = '0', int type = 0, String orientation = 'N', int size = 3, })

Prints a text string.

textData – the text to print. x, y – label origin coordinates. type – font type (0–6 = standard, 7 = Chinese). orientation – rotation: N, R, I, or B. size – font size (1=10px … 6=60px).

Implementation

Future<String?> printText(
  String textData, {
  String x = '0',
  String y = '0',
  int type = 0,
  String orientation = 'N',
  int size = 3,
}) async {
  try {
    final String? result = await _channel.invokeMethod('printText', {
      'textData': textData,
      'x': x,
      'y': y,
      'type': type,
      'orientation': orientation,
      'size': size,
    });
    return result;
  } on PlatformException catch (e) {
    throw 'Failed to print text: ${e.message}';
  }
}
