Geolocation class
A widget that provides user's geolocation to its widget subtree.
The widget automatically asks for user's permission as soon as requestPermissionIfNeeded is set to true
.
Any of the child's descendant can access the geolocation status by using Geolocation.of(context)
method.
If isEnabled is false
, no geolocation is get.
