OmniMapper Generator

Code generator for the omni_mapper package.

This package automatically generates type-safe object-to-object mapping code, eliminating boilerplate for converting between DTOs, Models, Entities, and ViewModels.

Installation

Add this package as a dev_dependency alongside build_runner, and add omni_mapper to your normal dependencies:

dependencies:
  omni_mapper: ^0.1.0

dev_dependencies:
  build_runner: ^2.4.0
  omni_mapper_generator: ^0.1.0

Features

• Extension-based mapping — generates clean extension methods on your classes
• Bidirectional mapping — use target (Model → Entity) or from (Entity → Model)
• Custom field mapping — rename fields between source and target
• Type converters — handle type mismatches with OmniConverter
• Default values — provide fallbacks for missing fields
• List generation — batch-map iterables automatically
• In-place updates — mutate existing objects without creating new ones
• Multi-mapper — map a single class to multiple targets with @OmniMappers

Usage

For detailed usage instructions and examples, please refer to the omni_mapper package documentation.
