Overview
The tuple package provides a lightweight, type-safe tuple data structure for Dart, enabling the grouping of multiple values of potentially different types into a single immutable object. It supports up to 7 elements and offers intuitive syntax for creation, access, and destructuring. Designed for simplicity and performance, it enhances code clarity when returning or passing multiple related values without defining custom classes. The library is particularly useful in functional programming patterns and scenarios requiring concise data aggregation.
Use cases
- Returning multiple values from functions
- Passing grouped data between methods
- Functional programming patterns
- Simplifying data transfer in state management
- Avoiding boilerplate for small data structures
Key features
- Immutable tuple objects
- Type safety across elements
- Support for up to 7 elements
- Destructuring via pattern matching
- Minimal runtime overhead
- Clean syntax for creation and access
Suitable for
- Developers seeking lightweight data containers
- Projects using functional programming styles
- Apps needing efficient multi-value returns
- Teams avoiding custom class definitions for simple data
- Cross-platform apps targeting all major platforms
Considerations
- Limited to 7 elements
- Not suitable for large or complex data models
- Immutability may require workarounds for mutable use cases
- Less discoverable than named classes for new developers
