This is a fork from sunmi_printer , but i implemented a lot of other features described below
THIS PACKAGE WILL WORK ONLY IN ANDROID!
Support Sunmi and Null Safety. I build this flutter plugin based on this: Official Sunmi Inner Printer Doc. But not all method from doc was included in this package, beacuse i don't have equipment. If you have and can help me, just contact me on github!

You can also combine this package with the package esc_pos_utils
With this package you can create a custom escpos and than you don't need to use any other command. This is good if you already have a code that another printers use, and u can reuse this code as well
#Just see the example folder!
// import packages
import 'package:sunmi_printer_plus/sunmi_printer_plus.dart';
// all method from sunmi printer need to async await
await SunmiPrinter.bindingPrinter(); // must bind the printer first. for more exmaple.. pls refer to example tab.
await SunmiPrinter.startTransactionPrint(true);
await SunmiPrinter.setAlignment(SunmiPrintAlign.RIGHT); // Right align
await SunmiPrinter.printText('Align right');
await SunmiPrinter.setAlignment(SunmiPrintAlign.LEFT);// Left align
await SunmiPrinter.printText('Align left');
await SunmiPrinter.setAlignment(SunmiPrintAlign.CENTER);// Center align
await SunmiPrinter.printText('Align center');
await SunmiPrinter.lineWrap(2); // Jump 2 lines
await SunmiPrinter.setFontSize(SunmiFontSize.XL); // Set font to very large
await SunmiPrinter.printText('Very Large font!');
await SunmiPrinter.resetFontSize(); // Reset font to medium size
await SunmiPrinter.setCustomFontSize(12); // SET CUSTOM FONT 12
await SunmiPrinter.printText('Custom font size!!!');
await SunmiPrinter.resetFontSize(); // Reset font to medium size
await SunmiPrinter.printQRCode('https://github.com/brasizza/sunmi_printer'); // PRINT A QRCODE
await SunmiPrinter.submitTransactionPrint(); // SUBMIT and cut paper
await SunmiPrinter.exitTransactionPrint(true); // Close the transaction
Example code for LCD functions @ytyng
await SunmiPrinter.lcdInitialize(); //Initialize the LCD
await SunmiPrinter.lcdWakeup(); //Turn the LCD ON
await SunmiPrinter.lcdSleep(); //Turn the LCD OFF
await SunmiPrinter.lcdClear(); //Clear LCD screen
await SunmiPrinter.lcdString('Hello'); //Write a simple line
await SunmiPrinter.lcdString('Hello'); //Write a simple line
await SunmiPrinter.lcdDoubleString('Hello', 'World'); //Write two lines
Uint8List byte = await readFileBytes('assets/images/128x40.png');
await SunmiPrinter.lcdImage(byte); // Put an image in LCD
await SunmiPrinter.lcdFillString('abcDEFgj0123\$&= ', size: 16, fill: true); // Print a string and fill with zeros until the size is reached
await SunmiPrinter.lcdMultiString([ 'Welcome to flutter.', 'Align 2.',], [ 1, 2,]); // Write multiple lines with alignent
Example to open the cashier @ZheruiL
bool await SunmiPrinter.drawerStatus(); //check if the cash drawer is connect or disconnect
await SunmiPrinter.openDrawer(); //open de cash drawer
int await SunmiPrinter.drawerTimesOpen(); //How many times de cash drawer was oppened
