## Usage

Flow graph:

```dart
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:

```dart
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(
			child: Text('Delete'),
			onTap: () {
				setter(() {
					node.deleteSelf();
				});
			},
			)
		];
	},
