Flutter GraphView is used to display data in graph structures. It can display Tree layout, Directed and Layered graph. Useful for Family Tree, Hierarchy View.
Since upgrading to beta 1.26.0-17.8.pre this last weekend I've noticed, not always, and some what randomly the following error in the terminal when calling GraphView with the SugiyamaAlgorithm. It doesn't seem to effect the running app:
======== Exception caught by rendering library =====================================================
The following IndexError was thrown during performLayout():
RangeError (index): Index out of range: index should be less than 1: 1
