While working with Laravel contracts, please note the following important points -
It is mandatory to define facades in the constructor of a class.
Contracts are explicitly defined in the classes and you need not define the contracts in constructors.
The contract uses a function can which includes a parameter named ability and arguments which uses the user identification in the form of an array.
You will have to define a contract as shown in the syntax below -
interface <contract-name>
Contracts are used like facades for creating robust, well-tested Laravel applications. There are various practical differences with usage of contracts and facades.
Contract contains no implementation and new dependencies;
It is easy to write an alternative implementation of a specified contract, thus a user can replace cache implementation without modifying any code base.
