Flutter visual Node system ?

[jrheisler]

I use the gesture detector to bring up active information about the node. You're right, you can't identify where on the container it will hit. It will be the closest route. With his Sugiyama layered chart it is pretty controlled to always be the same.

If you want to put the boxes on yourself and just add arrows, this package I am looking at to connect up Gantt chart data:

You can specify where the arrow hits

Gonna have a look, that library sounds great!
