Observations

• The named annotations or qualifiers are used to differentiate between two different values in a single class type that is being injected using the dagger.
• One such scenario is say you have an interface and 2 different implementations of the interface, Now you create 2 modules for this interface and then add both the modules in the component you are preparing. This would result in an error since dagger doesn't understand which implementation to use.
• We can resolve this by specifying a qualifier for this purpose.
