Arhitecture Patterns¶

Key Architectural Patterns

1. State Management: Centralized in HomeScreen with callbacks to update UI
2. Manager Pattern: Separate managers for different concerns (Thread, Shard, Point, Context, TreeView)
3. Immutable Updates: Points are copied with modifications, original data preserved
4. Tree Flattening: 3D tree structure flattened to 1D list for rendering
5. Lazy Loading: Only visible items rendered via SliverList.builder
6. Error Handling: Try-catch blocks throughout with fallbacks to prevent crashes
7. Reactive UI: setState() triggers rebuild only when data changes
