The sometimes method in Laravel allows for conditional application of validation rules based on specific conditions.
It is useful when you want to validate a field only if it is present in the request or when a certain condition is met.
For example, in a profile update form of an e-commerce app, you can use sometimes to validate the profile picture only if the user uploads one.
Using sometimes provides the flexibility to apply validation rules dynamically, making it a powerful tool for conditional validation in Laravel applications.
