Try this:

Expanded( child: InteractiveViewer( constrained: false, boundaryMargin: EdgeInsets.all(100), minScale: 0.01, maxScale: 5.6, child: GraphView( graph: graph, algorithm: BuchheimWalkerAlgorithm(builder, TreeEdgeRenderer(builder)), paint: Paint() ..color = Colors.green ..strokeWidth = 1 ..style = PaintingStyle.stroke, )), ),
