SankeyNode class
A node in the Sankey diagram.
Each node has a unique id and an optional label for display. Use displayLabel to get a non-null label (falls back to id.toString()).
Constructors
- SankeyNode({required dynamic id, String? label})
Properties
- bottom ↔ double
-
Bottom edge y-coordinate after layout
getter/setter pair
- depth ↔ int
-
Distance from source nodes (horizontal depth)
getter/setter pair
- displayLabel → String
-
Returns the label if set, otherwise falls back to id.toString()
no setter
- fixedValue ↔ double?
-
Optional fixed value override
getter/setter pair
- hashCode → int
-
The hash code for this object.

- height ↔ int
-
Distance to sink nodes
getter/setter pair
- id → dynamic
-
Unique identifier for this node
final
- index ↔ int
-
Index assigned during layout computation
getter/setter pair
- label ↔ String?
-
Optional display label for the node
getter/setter pair
- layer ↔ int
-
