A Flutter/Dart package that generates type-safe models and API clients from OpenAPI specifications using Freezed for immutable data classes and Dio for HTTP requests. It streamlines backend integration by automatically creating Dart code tailored to the API structure, reducing boilerplate and improving maintainability. Ideal for projects relying on REST APIs defined via OpenAPI (Swagger), it ensures consistency between API contracts and client implementations.
Use cases
- Automatically generate API clients from OpenAPI specs
- Create immutable data models with Freezed
- Simplify REST API integration in Flutter apps
- Maintain synchronization between API and client code
- Support multi-platform apps with shared API logic
Key features
- Code generation from OpenAPI documents

Suitable for
- Flutter developers using OpenAPI-defined APIs
- Teams needing consistent API-client generation
- Projects requiring immutable data models
- Apps targeting multiple platforms
- Developers wanting to reduce manual API code
Considerations
- Requires an OpenAPI specification file
- Generated code must be managed carefully during updates
