# sunmi_task_printer
## Important
**THIS PACKAGE WILL WORK ONLY IN ANDROID!**
It supports Sunmi and Null Safety. I developed this Flutter plugin based on the following:
[Official Sunmi Inner Printer Doc](https://file.cdn.sunmi.com/SUNMIDOCS/%E5%95%86%E7%B1%B3%E5%86%85%E7%BD%AE%E6%89%93%E5%8D%B0%E6%9C%BA%E5%BC%80%E5%8F%91%E8%80%85%E6%96%87%E6%A1%A3EN-0224.pdf).
However, not all methods from the documentation were included in this package because I don't have access to the equipment. If you have the equipment and can assist, please contact me on GitHub!
## Installation
```bash
flutter pub add sunmi_task_printer
```

## Tested Devices
```
Sunmi V2 Pro
Sunmi T2 mini
Sunmi V2S
```
## \*\*You can also combine this package with the
package [esc_pos_utils](https://pub.dev/packages/esc_pos_utils)\*\*
_With this package, you **can** create custom ESC/POS commands, eliminating the need for additional commands.
This is beneficial if you already have code that is compatible with other printers, as you can reuse that code as well._
# Just see the example folder!
```dart
// Import packages
import 'package:sunmi_task_printer/sunmi_task_printer.dart';
// All methods from Sunmi Task Printer do not require asynchronous calls.
SunmiTaskPrinter.bindingPrinter(); // The plugin handles asynchronous operations automatically.
```
## Get device info
```dart
// No need to use async/await for these operations
SunmiTaskPrinter.paperSize().then((int size) {
setState(() {
paperSize = size;
});
});
SunmiTaskPrinter.printerVersion().then((String version) {
setState(() {
printerVersion = version;
});
});
SunmiTaskPrinter.serialNumber().then((String serial) {
setState(() {
serialNumber = serial;
});
});
```
