A Flutter plugin for accessing the thermal printer on SunMi devices.

Tested on: SunMi V2 Pro

Probably works on other Sunmi devices equipped with SEIKO thermal printer.

Required permissions in AndroidManifest.xml:

<uses-permission android:name="android.permission.BLUETOOTH" />

Needed to set up a virtual Bluetooth connection to communicate with the printer on the device.

In android/app/build.gradle: Make sure minSdkVersion is set to 19 or above Add to your dependencies:

implementation group: 'com.google.zxing', name: 'core', version: '3.4.0'

// instantiate and queue your instructions
var printer = SunmiThermalPrinter()
  ..println('HELLO WORLD!')
  ..divider()
  ..qr('HELLO WORLD!', moduleSize: 8);
// execute printing
printer.exec();

See example app for a a detailed receipt example.
