Hello does someone successfully added Bluetooth CPCL on your Flutter project? - android-studio

Question

I tried to print in a ZEBRA ez320 Bluetooth printer I found out that it only works using cpcl code, the good news is I have the sample code for cpcl but I don't know how to integrate it on my Flutter project.
Can someone help me out?

This github https://github.com/devinim/flutter-zsdk has Zebra SDK Kit Flutter Integration
code snippet
devices = await FlutterZsdk.discoverBluetoothDevices();
devices.forEach((d) {
print('Device: ${d.friendlyName} [${d.mac}]');
});
...
d.sendZplOverBluetooth(FLUTTER_LOGO_ZPL),
