Factory Pattern
Last updated
What is Factory Pattern?
The Factory pattern provides an interface for creating objects without specifying their exact class. It centralizes object creation logic, making it easier to swap implementations without modifying calling code. In Android, factory patterns appear in ViewModelProvider.Factory for creating ViewModels with custom constructor arguments.
