Short answer:

Install latlong2 package simply by doing flutter pub add latlong2

Long answer:

On the right side of pub.dev you can find a dependency list, in this case it's this:

You should already be able to do import 'package:latlong2/latlong.dart'; but probably the linter will notify you not to use dependencies that are not defined in your pubspec.yaml, so you have to explicitly add latlong2: ^x.x.x to your pubspec.
