have you found a solution by any chance?
is this answered?
I did it like this
https://github.com/CaptainDario/DaKanji/blob/main/lib/widgets/dictionary/kanji_group_widget.dart#L78
Which results in smth like this
I stumbled accross the same issue and here's my solution that is more dynamic (works well when the child graph is smaller than the viewport as well as bigger)
@override
Widget build(BuildContext c) {
return InteractiveViewer(
constrained: false,
boundaryMargin: const EdgeInsets.all(100),
minScale: 0.01,
maxScale: 5.6,
child: ConstrainedBox(
constraints: BoxConstraints(
minWidth: MediaQuery.of(context).size.width,
minHeight: MediaQuery.of(context).size.height,
),
child: Center(
child: GraphView(
graph: graph,
algorithm: BuchheimWalkerAlgorithm(builder, TreeEdgeRenderer(builder)),
paint: Paint()
..color = Constant.primaryColor
..strokeWidth = 1
..style = PaintingStyle.stroke,
builder: (Node node) => (node as MNode).builder(context, draggedTarget),
),
),
),
);
}
Thank you for the great package!
I am trying to show a graph and I want that it is centered and scaled to a size so that the whole graph is visible. Is this possible?
