retrofit.dart is a Dart code generator that creates type-safe HTTP API clients for the dio package using annotations and source_gen, inspired by Retrofit and Chopper. Developers define abstract REST API classes and build_runner generates the implementation code with JSON type conversion.

Use cases

• generate type-safe HTTP clients in Dart
• declarative REST API definitions with annotations
• auto-convert JSON responses to Dart objects
• reduce boilerplate in Flutter network layers
• define API endpoints as abstract classes
• integrate dio with code generation via build_runner

When to choose

• you're building a Flutter or Dart app that consumes REST APIs
• you want Retrofit-style declarative API clients in Dart
• you want automatic JSON serialization wired into your HTTP layer
• you want to eliminate repetitive dio client code

When to avoid

• you don't use dio as your HTTP client
• you prefer writing HTTP calls manually without code generation
• your project avoids build_runner/source_gen build steps
• you need a client for non-REST protocols
