In Dart, if the leading character is an underscore, then the function/constructor is private to the library.
Class._(); is a named constructor (another example might be the copy constructor on some object in Flutter: AnotherClass.copy(...);).
The Class._(); isn’t necessary unless you don’t want Class to ever be accidentally instantiated using the implicit default constructor.
