The official Flutter Plugin to integrate the Brady SDK within a Flutter application. The Brady SDK will allow users to discovery, connect, and print to Brady printers.

Getting Started

To demonstrate the basic functionalities of the Brady SDK Flutter Plugin, the Dart code used to test this plugin is copy and pasted below.

MAIN.DART

import 'package:flutter/material.dart';
import 'dart:async';
import 'dart:convert';
import 'package:flutter/services.dart';
import 'package:brady_flutter_plugin/brady_flutter_plugin.dart';

void main() {
runApp(const MyApp());
}

class MyApp extends StatefulWidget {
const MyApp({super.key});

@override
State<MyApp> createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
String _platformVersion = 'Unknown';
final _bradyFlutterPlugin = BradyFlutterPlugin();

@override
void initState() {
super.initState();
initPlatformState();
}

// Platform messages are asynchronous, so we initialize in an async method.
Future<void> initPlatformState() async {
String platformVersion;
// Platform messages may fail, so we use a try/catch PlatformException.
// We also handle the message potentially returning null.
try {
platformVersion =
await _bradyFlutterPlugin.getPlatformVersion() ?? 'Unknown platform version';
} on PlatformException {
platformVersion = 'Failed to get platform version.';
}

    // If the widget was removed from the tree while the asynchronous platform
    // message was in flight, we want to discard the reply rather than calling
    // setState to update our non-existent appearance.
    if (!mounted) return;

    setState(() {
      _platformVersion = platformVersion;
    });
}

Future<void> discover() async {

}

}
}
}
}

final bytes = byteData.buffer.asUint8List();
_bradyFlutterPlugin.setTemplate(base64.encode(bytes));

}
}

Future<void> disconnect() async {
final disconnected = await _bradyFlutterPlugin.disconnect();
if (disconnected == true) {

}
else {

}
