📖 Basic Usage

UART Device Example

import 'package:rfid_flutter_android/rfid_flutter_android.dart';

// Initialize RFID module
final initRes = await RfidWithUart.instance.init();
print(initRes.isEffective ? 'Initialization successful' : 'Initialization failed: ${initRes.error}');
// Release RFID module
final freeRes = await RfidWithUart.instance.free();
print(freeRes.isEffective ? 'Release successful' : 'Release failed: ${freeRes.error}');

// Listen to inventory data
StreamSubscription<List<RfidTagInfo>> tagSubscription = RfidWithUart.instance.rfidTagStream.listen((tags) {
  for (final tag in tags) {
    print('Found tag: ${tag.epc}');
  }
});
// Stop listening to inventory data
tagSubscription.cancel();

// Start inventory
final startRes = await RfidWithUart.instance.startInventory();
print(startRes.isEffective ? 'Start inventory successful' : 'Start inventory failed: ${startRes.error}');
// Stop inventory
final stopRes = await RfidWithUart.instance.stopInventory();
print(stopRes.isEffective ? 'Stop inventory successful' : 'Stop inventory failed: ${stopRes.error}');

// Set frequency
final setFrequencyRes = await RfidWithUart.instance.setFrequency(RfidFrequency.china2);
print(setFrequencyRes.isEffective ? 'Set successful' : 'Set failed: ${setFrequencyRes.error}');
// Get frequency
final getFrequencyRes = await RfidWithUart.instance.getFrequency();
print(getFrequencyRes.result ? 'Get successful' : 'Get failed: ${getFrequencyRes.data}');

// Set power to 20
final setPowerRes = await RfidWithUart.instance.setPower(20);
print(setPowerRes.isEffective ? 'Set successful' : 'Set failed: ${setPowerRes.error}');
// Get power
final getPowerRes = await RfidWithUart.instance.getPower();
print(getPowerRes.result ? 'Get successful' : 'Get failed: ${getPowerRes.data}');

Barcode Example

import 'package:rfid_flutter_android/rfid_flutter_android.dart';

// Initialize barcode scanner
final initRes = await BarcodeDecoder.instance.init();
print(initRes.isEffective ? 'Initialization successful' : 'Initialization failed: ${initRes.error}');
// Release barcode scanner
final freeRes = await BarcodeDecoder.instance.free();
print(freeRes.isEffective ? 'Release successful' : 'Release failed: ${freeRes.error}');

// Listen to barcode data
StreamSubscription<RfidBarcodeInfo> barcodeSubscription = BarcodeDecoder.instance.barcodeStream.listen((barcodeInfo) {
  print(barcodeInfo.toString());
});
// Stop listening to barcode data
barcodeSubscription.cancel();

// Start barcode scanning
final startRes = BarcodeDecoder.instance.startScan();
// Stop barcode scanning
final stopRes = BarcodeDecoder.instance.stopScan();
