Mvvm architecture representation

• Here in the diagram we can say the classes below are the dependencies of the classes above.
• This is because the class above depends on the class below.
• best possible way to provide the dependencies needed for the class is to instantiate in the constructor of the class but this is not the correct way.
• We instantiate the dependencies outside and provide them in the constructor.
• Also we can share the dependencies here thus using only one instance of dependency instead of creating many instances.
