If you use @ionic-native/google-maps, please tell the package.json (only @ionic-native/core and @ionic-native/google-maps are fine mostly)

"@ionic-native/core": "^4.7.0",
"@ionic-native/google-maps": "^4.7.0",

Current behavior: setCameraTarget throws an error. I’m trying to set the camera with multiple ILatLng objects, to bound the map to their locations.

Expected behavior: Should work.
