您可以使用device_info_plus包来检索CPU体系结构。

import 'package:device_info_plus/device_info_plus.dart';

DeviceInfoPlugin deviceInfo = DeviceInfoPlugin();

if (Platform.isAndroid) {
  AndroidDeviceInfo androidInfo = await deviceInfo.androidInfo;
  print('CPU architecture: ${androidInfo.supportedAbis}');
} else if (Platform.isIOS) {
  IosDeviceInfo iosInfo = await deviceInfo.iosInfo;
  print('CPU architecture: ${iosInfo.utsname.machine}');
}
