What is dependency injection give example?

What is dependency injection? Classes often require references to other classes. For example, a Car class might need a reference to an Engine class . These required classes are called dependencies, and in this example the Car class is dependent on having an instance of the Engine class to run.

Dependency Injection is a way of making the dependencies of an object available via another object , and these dependencies are usually known as services. … In dart, the most basic way to handle dependency injection is by passing services to a class through the constructor.

Dependency injection is simply a way of making a class independent of its own dependencies. It allows you to separate different parts of your application in a more maintainable way, because every class can make calls to any dependency it needs .26 Oca 2022
