Factory constructors in Flutter

A Thread 👇

#flutter #OpenSource #100DaysOfCode

The factory keyword returns an instance of the given class that’s not necessarily a new one. It
can be useful when:

=> You want to return an instance of a subclass instead of the class itself

=> You want to implement a singleton (the Singleton pattern)

=> You want to return an instance from a cache.

Factory constructors are like static methods and so they don’t have access to this. There cannot
be together a factory and a "normal" constructor with the same name.
