pixelForCoordinate method
Calculates a screen coordinate that corresponds to a geographical coordinate
(i.e., longitude-latitude pair).
The screen coordinate is in logical pixels relative to the top left corner
of the map (not of the whole screen).
Implementation
Future<ScreenCoordinate> pixelForCoordinate(
Map<String?, Object?> coordinate) =>
_cameraManager.pixelForCoordinate(coordinate);
