fromJson static method
Returns a new MOSStats instance and imports its values from
value
if it's a Map, null otherwise.
Implementation
// ignore: prefer_constructors_over_static_methods

final json = value.cast<String, dynamic>();
// Ensure that the map contains the required keys.
// Note 1: the values aren't checked for validity beyond being non-null.
// Note 2: this code is stripped in release mode!
