Visa – Easy third party auth (OAuth 2.0) for flutter apps

In plain words

Visa is an OAuth 2.0 authentication library for Flutter applications that simplifies integrating third-party login systems. Developers use it to add social or federated sign-in options to their Flutter apps without building authentication from scratch. The package handles the OAuth flow and credential management, reducing implementation complexity. It's designed for Flutter developers who need quick third-party authentication integration.

There were stupid user journey things that I knew needed fixed. There were some features I knew needed added. And I knew the pricing was wrong.
