⚙️ Android Configuration

IMPORTANT: Add Maven Repository

The Zebra RFID SDK is hosted on GitHub. You need to add the repository to your app's Gradle configuration.

📘 Kotlin DSL (build.gradle.kts) - Click to expand

If your app uses Kotlin DSL, add this to your_app/android/build.gradle.kts:

allprojects {
    repositories {
        google()
        mavenCentral()
        
        // Add Zebra RFID SDK repository
        maven {
            url = uri("https://raw.githubusercontent.com/devJimmy990/rfid_zebra_reader/main/android/maven")
        }
    }
}

📗 Groovy (build.gradle) - Click to expand

If your app uses Groovy, add this to your_app/android/build.gradle:

allprojects {
    repositories {
        google()
        mavenCentral()
        
        // Add Zebra RFID SDK repository
        maven {
            url "https://raw.githubusercontent.com/devJimmy990/rfid_zebra_reader/main/android/maven"
        }
    }
}

That's it! The plugin will automatically download and configure the Zebra SDK.

🚀 Quick Start

import 'package:rfid_zebra_reader/rfid_zebra_reader.dart';

// Initialize SDK
await ZebraRfidReader.initialize();

// Listen for tag events
ZebraRfidReader.eventStream.listen((event) {
  if (event.type == RfidEventType.tagRead) {
    print('Tags: ${event.tags}');
  }
});

// Connect to reader
await ZebraRfidReader.connect();

// Start scanning
await ZebraRfidReader.startInventory();

// Stop scanning
await ZebraRfidReader.stopInventory();
