react-native-maps region change events have two properties-- latitudeDelta & longitudeDelta-- that represent the span in degrees between the top & bottom or left & right part of the map, respectively.
This may be a breaking change for some apps since the Region returned is now complete and contains all four properties instead of just latitude/longitude, let me know if you want a version bump.
