Overview
A lightweight Dart library inspired by functional programming, offering the `Either` type for robust error handling. It enables safe computation by representing results as either a successful value (`Right`) or an error (`Left`). This approach helps avoid exceptions and promotes explicit error management in code. The library is ideal for developers seeking cleaner, more predictable control flow in asynchronous and functional workflows. It integrates seamlessly with Dart’s ecosystem and supports all major platforms.
Use cases
- Error handling in async operations
- Functional-style data processing
- Safe parsing and validation
- Replacing try-catch blocks
- Composing error-prone functions
- Building resilient business logic
Key features
- Provides `Either<Left, Right>` type
- Supports functional composition
- Immutable and type-safe
- Minimal boilerplate
- Works with async/await
- Cross-platform compatibility
Suitable for
- Developers using functional programming patterns
- Teams prioritizing error safety
- Projects requiring clean error propagation
- Dart developers avoiding exceptions
- Those building reusable, composable logic
- Applications needing predictable state transitions
Considerations
- Requires understanding of functional concepts
- May increase learning curve for beginners
- Not suitable for simple error cases
- Limited to use with explicit error types
- Best paired with other FP utilities
- Needs careful type alignment in complex chains
