Stateless questions

The main advantages of using JWT for authentication include statelessness, scalability, and flexibility. JWTs are stateless, meaning all necessary information for authentication is contained within the token, reducing the need for server-side session storage. This stateless nature enhances scalability, as tokens can be validated independently by multiple servers or services. JWTs are also flexible, supporting various signing algorithms and claim types, allowing for customized authentication and authorization mechanisms. Additionally, their compact and URL-safe format makes them suitable for modern web and mobile applications.

A Stateless Widget is immutable and cannot change its state once built. It's used when the UI doesn't depend on any data that might change. For instance, a text label that always displays the same text can be implemented as a Stateless Widget, as it doesn't require any dynamic updates.
