Answer 1

这不是错误

这与平台特定的编码无关，如@challenget回答

您只需要重新构建并再次运行该应用程序，即可添加flutter-plugin并使其正常工作。

热重启将不起作用

Answer 2

DeviceInfoPlugin deviceInfo = DeviceInfoPlugin();
if (Platform.isAndroid) {
  AndroidDeviceInfo androidInfo = await deviceInfo.androidInfo;
} else if (Platform.isIOS) {
  IosDeviceInfo iosInfo = await deviceInfo.iosInfo;
}

您需要判断设备。

Answer 3

停止应用程序并重新启动构建。这对我有用。

找不到方法getAndroidDeviceInfo的实现
