Auth0 Flutter Web Integration

auth0_flutter is the official Auth0 SDK for Flutter applications. On the web platform, it wraps the Auth0 SPA JS SDK to provide browser-based authentication via redirect or popup flows with built-in credential caching and automatic token renewal.

Agent instruction: The current SDK version is 2.1.0. Use this version in all dependency lines below. If you need to verify, run flutter pub add auth0_flutter which will resolve the latest compatible version automatically.

When NOT to Use

• Flutter mobile (iOS/Android): Use auth0-flutter-native — mobile uses a different platform interface with Web Auth via system browser
• Native iOS (Swift): Use auth0-swift
• Native Android (Kotlin/Java): Use auth0-android
• React SPA: Use auth0-react
• Angular SPA: Use auth0-angular
• Vue SPA: Use auth0-vue
• Node.js/Express servers: Use auth0-express
