PointField.fromJson constructor

PointField.fromJson(
  1. Map<String, dynamic> json
)

Parse the incoming json and return a PointField Usage, assuming that u parse a incoming json source, then the runtime type is a _InternalLinkedHashMap: PointField.fromJson(Map<String, dynamic>.from(elem'location'))

Implementation

factory PointField.fromJson(Map<String, dynamic> json) {
  /// Create a variable with the type of the Field, to reconstruct the incoming json data.
  String type = json['type'];

  /// Create a variable with a list of a list with coordinates.
  List<double> coordinates = json['coordinates'].cast<double>();

  /// Return a [MultiLineStringField] with the variables [type] and [coordinates]
  return PointField(
      type: type,
      coordinates: coordinates
  );
}
