如何使用flutter_blue检测Mindstorm EV3

dependencies:
  flutter_blue: ^0.7.3

import 'package:flutter_blue/flutter_blue.dart';

FlutterBlue flutterBlue = FlutterBlue.instance;
StreamSubscription<ScanResult> scanSubscription;

void startScan() {
  scanSubscription = flutterBlue.scan().listen((scanResult) {
    if (scanResult.device.name == 'Mindstorm EV3') {
      // 找到Mindstorm EV3设备
      stopScan();
      connectToDevice(scanResult.device);
    }
  });
}

void stopScan() {
  scanSubscription?.cancel();
}

void connectToDevice(BluetoothDevice device) async {
  await device.connect();
  // 连接到设备后，可以执行其他操作，如读取、写入特征值等
}

void readCharacteristic(BluetoothCharacteristic characteristic) async {
  List<int> value = await characteristic.read();
  // 处理读取到的数据
}

void writeCharacteristic(
    BluetoothCharacteristic characteristic, List<int> value) async {
  await characteristic.write(value);
  // 写入数据到特征值
}

void disconnectDevice(BluetoothDevice device) {
  device.disconnect();
}
