no setter

final
customMidMarkerPath → String: Path to the custom icon asset used for midpoint markers.
final
distanceMarkers → Set<Marker>: Set of distance markers showing distances between points.
no setter
fillColor → Color: Fill color used when a polygon is completed.
final
hashCode → int: The hash code for this object.
no setterinherited
hasInteracted → bool: Returns true if the user has interacted with the map.
no setter

inherited
notifyListeners() → void: Call all the registered listeners.
inherited
redoLastPoint() → void: Restores the last undone point and updates shapes.

setMapController(GoogleMapController controller) → void: Sets the GoogleMapController for this view model.
toString() → String: A string representation of this object.
