I am experiencing the same issue with the latest version of the Flutter master channel and it looks like it could be related to this. It looks like the Android platform of this plugin needs to be updated to implement both FlutterPlugin and MethodCallHandler in order to support the two different methods of plugin registration. I have been able to make a start on adding support for these two different methods of plugin registration, however I have unfortunately hit a blocker on the FlutterView because it has since been deprecated.

I was having the same error and in my case adding this to the application tag inside the manifest.xml file:

android:requestLegacyExternalStorage="true" and this to the info.plist file:

` NSLocationWhenInUseUsageDescription

This app needs access to location when open.

<key>NSLocationAlwaysUsageDescription</key>
<string>This app needs access to location when in the background.</string>`

solved it.
