Dear @zhengxiangke,

Thanks for your issue. I've looked into the issue and according to the README the following could be happening:

1. This plugin uses the free Geocoding services provided by the iOS and Android platforms. This means that there are restrictions to their use. More information can be found in the [Apple documentation for iOS](https://developer.apple.com/documentation/corelocation/clgeocoder) and the [Google documentation for Android](https://developer.android.com/reference/android/location/Geocoder).
   When a `PlatformException(IO_ERROR, ...)` gets thrown, most of the times it means that the rate limit has been reached.
2. The availability of the Google Play Services depends on your country. If your country doesn't support a connection with the Google Play Services, you'll need to try a VPN to establish a connection. For more information about how to work with Google Play Services visit the following link: https://developers.google.com/android/guides/overview 

Can you check if one of the issues may apply to your situation?

Kind regards,
