Overview
A Dart package that provides an Ordered Set implementation supporting multiple items with identical priority. It maintains insertion order for elements with the same priority, enabling predictable and efficient sorting in applications requiring ordered collections. Ideal for use cases where duplicate priorities are expected but order preservation is essential. The package is lightweight, compatible across all major platforms, and integrates seamlessly with Flutter projects via pub.dev.
Use cases
- Priority-based task scheduling
- Maintaining ordered logs with duplicates
- Implementing priority queues with tie-breaking
- Managing event sequences with equal urgency
- Custom sorting in data pipelines
- Real-time data processing with order constraints
Key features
- Supports multiple items with same priority
- Preserves insertion order within equal priorities
- Cross-platform compatibility
- Lightweight and easy to integrate
- Efficient lookup and insertion
- No external dependencies
Suitable for
- Developers needing ordered collections with duplicate priorities
- Applications requiring deterministic ordering
- Flutter apps with complex data sorting needs
- Systems managing time-sensitive or priority-driven workflows
- Engineers building custom queue or buffer systems
Considerations
- Not suitable for high-frequency updates due to performance trade-offs
- Limited to single-key ordering (no multi-level sorting)
- Requires manual handling of priority changes
- Best suited for moderate-sized datasets
- Does not support reverse iteration natively
- May consume more memory than standard sets when many duplicates exist
