force_directed_graphview library
Classes
-
AnimatedDashEdgePainter<
N extends NodeBase, E extends EdgeBase< N> > - A painter for drawing a moving dash line between nodes.
-
AnimatedEdgePainter<
N extends NodeBase, E extends EdgeBase< N> > - Interface for painting animated edges.
-
BottomLabelBuilder<
N extends NodeBase> - Label builder that places the label below the node.
-
DefaultNodeBuilder<
N extends NodeBase> - Dumb implementation of NodeBuilder.
-
Edge<
N extends NodeBase, T> - Model that represents a edge in the graph.
-
EdgeBase<
N extends NodeBase> - Base class for all edges
-
EdgePainter<
N extends NodeBase, E extends EdgeBase< N> > - Interface for painting edges.
- FruchtermanReingoldAlgorithm
- An implementation of Fruchterman-Reingold algorithm
- GraphCanvasSize
- Defines the size of the graph canvas. Note that this size won't change dynamically after the graph changed, so take the potential graph changes into account.
- GraphCanvasSizeFixed
- The size of the graph canvas is fixed.
- GraphCanvasSizeProportional
- The area of the graph canvas is defined by the total area of the nodes multiplied by areaFactor. The final size is calculated by the square root of the area.
-
GraphController<
N extends NodeBase, E extends EdgeBase< N> > - Controller to manipulate the GraphView.
- GraphLayout
- Layout of the graph. Contains the positions of all nodes.
- GraphLayoutAlgorithm
- An interface for graph layout algorithm
- GraphLayoutBuilder
- Builder for the graph layout. Used to manipulate a mutable graph structure and the build an immutable GraphLayout instance.
-
GraphMutator<
N extends NodeBase, E extends EdgeBase< N> > - Wrapper around GraphController that allows changing the graph in a batch to avoid unnecessary rebuilds.
-
GraphView<
N extends NodeBase, E extends EdgeBase< N> > - A widget that displays a graph.
-
LabelBuilder<
N extends NodeBase> - Interbase class for label builders.
- LazyBuilding
- Defines how nodes are built.
- LazyBuildingNone
- No lazy building is used.
- LazyBuildingViewport
- Only nodes inside the viewport are built. The viewport is defined by the visible canvas area multiplied by scale.
-
LineEdgePainter<
N extends NodeBase, E extends EdgeBase< N> > - A painter for painting edges as lines. Draws a straight line between
-
Node<
T> - Default implementation of NodeBase
- NodeBase
- Base class for all nodes
-
NodeBuilder<
N extends NodeBase> - Helper class that helps to overcome dart type system limitations when working with functions. Currently should not be used directly.
Typedefs
- ChildBuilder = Widget Function(BuildContext context, Widget child)
-
A builder that should be used to wrap a
childwith something. - InitialNodePositionExtractor = Offset Function(NodeBase node, Size canvasSize)
- A function that extracts the initial position of the node
-
NodeViewBuilder<
N extends NodeBase> = Widget Function(BuildContext context, N node) - Callback for building a widget for a node
