Usage

Flow graph:

FlowGraphView(
	root: root,
	direction: _direction,
	centerLayout: _centerLayout,
	builder: (context, node) {
		return Container(
		color: Colors.white60,
		padding: const EdgeInsets.all(16),
		child: Text(
			node.data.toString(),
			style: const TextStyle(color: Colors.black87, fontSize: 16),
		),
		);
	},
)

Draggable flow graph:

DraggableFlowGraphView<FamilyNode>(
	root: root,
	direction: _direction,
	centerLayout: _centerLayout,
	willConnect: (node) => true,
	willAccept: (node) => true,
	builder: (context, node) {
	return Container(
		color: Colors.white60,
		padding: const EdgeInsets.all(16),
		child: Text(
			(node.data as FamilyNode).name,
			style: const TextStyle(color: Colors.black87, fontSize: 16),
			),
		);
	},
	nodeSecondaryMenuItems: (node) {
		return [
			PopupMenuItem(
