Widget ZPL Converter

The widget_zpl_converter package helps convert any Flutter widget to a ZPL/ZPL2 command. This is mainly targeted towards developers who need to print labels using thermal printers.

Features

  • Convert any Flutter widget to a ZPL/ZPL2 command.
  • ZPL/ZPL2 command can be sent to a thermal printer using esc_pos_utils's Generator.rawBytes() method, or any other packages with similar functionality.
  • Supports variable widget sizes (while maintaining aspect ratio).

Usage

To use this package, simply add widget_zpl_converter as a dependency in your pubspec.yaml file:

dependencies:
  widget_zpl_converter: ^1.0.0

Then, import the package in your Dart code:

import 'package:widget_zpl_converter/widget_zpl_converter.dart';

Create a widget that you want to convert to a ZPL/ZPL2 command:

final myWidget = Container(
  width: 100,
  height: 100,
  color: Colors.blue,
);

Create a ZplConverter object and pass the widget to the constructor:

final zplConverter = ZplConverter(myWidget);

You can then use the toZpl() method to convert any Flutter widget to a ZPL/ZPL2 command:

final zplCommand = zplConverter.toZpl();
