A Dart package that provides an annotation to automatically generate `copyWith` extension methods for classes using the `copy_with_extension_gen` code generator. This simplifies immutable object updates by allowing developers to create new instances with modified fields without manually writing boilerplate code. The generated extensions are type-safe and integrate seamlessly into Flutter and Dart projects across multiple platforms. It enhances code maintainability and reduces errors in state management and model classes.
Use cases
- Simplifying immutable data class updates
- Reducing boilerplate in state management
- Generating type-safe copy operations
- Enhancing model class usability
- Streamlining Flutter app development
- Supporting reactive programming patterns
Key features
- Annotation-based code generation
- Type-safe `copyWith` extensions
- Cross-platform support
- Minimal boilerplate
- Integration with `copy_with_extension_gen`
- Automatic field-by-field updates
Suitable for
- Flutter developers using immutable models
- State management with immutable data
- Teams prioritizing code cleanliness
- Projects using code generation
- Developers working with complex data structures
- Apps requiring frequent data mutations
Considerations
- Requires code generation setup
- Depends on `copy_with_extension_gen`
- Needs build_runner for generation
- May increase build time
- Not suitable for runtime-only scenarios
- Limited to annotated classes
