A Flutter plugin to create information to send to phomemo printers.
Getting started #
To get started with phomemo add the package to your pubspec.yaml file.
Generate a widget image #
Generates an image to send to the printer to print. Set the size as the size of the label. The example below has a height of 12mm with a infinately long length.
GlobalKey key = GlobalKey();
Size labelSize = const Size(double.infinity,12);

Widget widget = Container(
width: (labelSize.width * 3)+30,
height: (labelSize.height * 3)+30,
margin: const EdgeInsets.only(top:5),
padding: const EdgeInsets.fromLTRB(15, 15, 15, 15),
color: Theme.of(context).focusColor,
child: RepaintBoundary(
key: key,
child: child,
)
);

img.Image? image = await PhomemoHelper.generateImageFromWidget(key);

Generate a text image #
Generates an image to send to the printer to print. Set the size as the size of the label. The example below has a height of 12mm with a infinately long length.
img.Image? text = await PhomemoHelper.generateImageFromText(
TextSpan(
text: 'text here',
style: const TextStyle(
fontSize: 34,
color: Colors.black
),
),
size: Size(double.inifity,12), //Change this to the lable size
);

Send info to the printer #
Generate the data to send to the printer. Put the function to send to your printer in the class itself. In this case it is sending to a ble printer usng flutter_blue_plus.
Phomemo label = Phomemo(send: bluetooth.write, read: bluetooth.read);
PhomemoPrinter printer = helper.getPrinterFromName(bluetooth.device!.name);

await label.printLabel(
[img.decodePng(qrCode!.buffer.asUint8List()),letter],// the images to send to the printer
printer: printer, //The printer that will be printed on
spacing: 5, //space between images. Only works for D30, and D35 printers
rotate: printer != PhomemoPrinter.m220 // do not rotate the image if using the m220 or m110
labelSize: Size(double.infinity,12), //size of the label
);
