Overview
Built Value Generator is a code generation tool for Dart that enables the creation of immutable value classes with built-in builders, enum-like behavior, and seamless JSON serialization. It generates boilerplate code for constructors, getters, and serialization methods, reducing errors and improving code maintainability. Designed as a dev dependency, it works alongside built_value to streamline data modeling in Flutter and Dart applications. The generator supports multiple platforms including Android, iOS, macOS, Windows, and Linux.
Use cases
- Immutable data modeling
- JSON serialization
- Type-safe configuration objects
- State management in apps
- Code generation for complex data structures
Key features
- Automatic builder pattern generation
- Enum-like class behavior
- Built-in JSON serialization
- Minimal boilerplate
- Supports null safety
Suitable for
- Flutter apps requiring immutable data
- API-driven applications
- Large-scale state management
- Teams prioritizing type safety
- Projects using code generation
Considerations
- Requires build_runner setup
- Adds build-time dependency
- Limited runtime customization
- Not suitable for dynamic data
- Needs careful migration from mutable classes
