Flutter -如何在不使用包的情况下获取mac地址

import 'dart:io';

void main() async {
  try {
    List<NetworkInterface> interfaces = await NetworkInterface.list(
        includeLoopback: false, type: InternetAddressType.IPv4);
    for (NetworkInterface interface in interfaces) {
      for (InternetAddress address in interface.addresses) {
        if (address.type == InternetAddressType.IPv4) {
          print('MAC地址: ${interface.hardwareAddress}');
        }
      }
    }
  } catch (e) {
    print('获取MAC地址失败: $e');
  }
}
