商米打印机新增flutter插件：flutter_sunmi_printer

它可以打印带有样式（粗体、下划线、对齐、字体大小）、表格（使用类似 Bootstrap 的网格系统）、图像等的文本。

import 'package:flutter_sunmi_printer/flutter_sunmi_printer.dart';

// Text with styles
SunmiPrinter.text('left');
SunmiPrinter.text(
    'center',
    styles: SunmiStyles(bold: true, underline: true, align: SunmiAlign.center),
);
SunmiPrinter.text(
    'right',
    styles: SunmiStyles(bold: true, underline: true, align: SunmiAlign.right),
);

// Table
SunmiPrinter.row(
    cols: [
        SunmiCol(text: 'col1', width: 4),
        SunmiCol(text: 'col2', width: 4, align: SunmiAlign.center),
        SunmiCol(text: 'col3', width: 4, align: SunmiAlign.right),
    ],
);

// Image
ByteData bytes = await rootBundle.load('assets/rabbit_black.jpg');
final buffer = bytes.buffer;
final imgData = base64.encode(Uint8List.view(buffer));
SunmiPrinter.image(imgData);
