Overview
A Flutter package designed to visualize tree data structures in a hierarchical UI. It enables developers to render nested data as interactive tree views, supporting dynamic expansion and collapse of nodes. The package emphasizes clean, recursive rendering logic and is optimized for performance with large datasets. Ideal for applications requiring structured data representation such as file explorers, organizational charts, or category hierarchies. Built with Flutter's widget system, it integrates seamlessly across all major platforms.
Use cases
- Displaying file system directories
- Rendering organizational charts
- Showing category and subcategory hierarchies
- Building configuration trees
- Visualizing JSON or XML data structures
Key features
- Recursive node rendering
- Expandable and collapsible nodes
- Customizable node styling
- Support for deep nesting
- Cross-platform compatibility
- Efficient rendering for large trees
Suitable for
- Developers building hierarchical data interfaces
- Apps needing interactive tree navigation
- Projects with nested data models
- UIs requiring visual tree structure
- Flutter apps targeting multiple platforms
Considerations
- May require optimization for very large trees
- Custom styling requires understanding of Flutter widgets
- Limited built-in interactivity beyond expand/collapse
- Not suitable for flat data structures
- Performance depends on node complexity
