NodeFlowMinimap<T> class
A minimap widget that provides an overview of the entire node flow graph.
The minimap shows a bird's-eye view of all nodes in the graph along with a viewport indicator showing the currently visible area. Users can interact with the minimap to navigate the graph by clicking or dragging.
Features:
- Displays all nodes as simplified rectangles
- Shows current viewport bounds as a highlighted region
- Interactive navigation: click to jump, drag to pan
- Customizable appearance via MinimapTheme
- Reactive updates via MobX when graph changes
Example:
NodeFlowMinimap<MyData>(
controller: controller,
theme: MinimapTheme.light.copyWith(
nodeColor: Colors.blue,
),
interactive: true,
)
The minimap is typically placed in a corner of the editor as an overlay. See MinimapOverlay for automatic positioning.
