The Dart implementation of the atSDK for building applications on the Atsign Platform, a protocol for personal data ownership and controlled sharing. It provides the core client SDK, Flutter layers, and supporting libraries for authentication, cryptography, and protocol communication.

Use cases

• build mobile apps on the atProtocol
• add Atsign authentication and onboarding to a Flutter app
• encrypt and sign data with at_chops
• implement end-to-end encrypted data sharing between users
• build CLI or IoT clients that talk to atProtocol servers
• manage contacts across Atsign Platform apps

When to choose

• you are building Dart or Flutter apps that integrate with the Atsign Platform
• you need user-owned, end-to-end encrypted data exchange without a backend
• you want platform-neutral Dart SDK support for CLI, headless services, or IoT devices

When to avoid

• you need a general-purpose backend framework or database
• your project does not use Dart or Flutter and you need a different language binding
• you need Flutter web support, which is not a supported target
