Overview
The oauth2 package is a Dart client library that enables applications to authenticate with remote services using the OAuth2 protocol. It facilitates user authorization, token management, and secure HTTP requests using obtained OAuth2 credentials. Designed for use across multiple platforms—including mobile, web, and desktop—it simplifies integration with OAuth2-supported APIs such as Google, GitHub, and others. The package handles flows like authorization code and implicit grant, ensuring secure and standardized authentication workflows.
