screenCoordinate method Null safety

Future<ScreenCoordinate> screenCoordinate(
  1. Map<String?, Object?> arg_coordinate
)

Calculate screen coordinate on the snapshot from geographical coordinate.

@param coordinate A geographical coordinate. @return A screen coordinate measured in platform pixels on the snapshot for geographical coordinate.
