Paint is not always complete

[jrheisler]

I noticed with some graphs when you zoom you lose part of the painting:

This is with graphview: ^0.6.5 Flutter (Channel beta, 1.24.0-10.2.pre, on Microsoft Windows [Version 10.0.19041.685], locale en-US)

Fyi, this only happens when you pan and zoom are allowed.

Any updates or fixes for this issue? I have similar black artifacts when zoomin in.

I always had an issue with the Zooming of the libary. Did not come to the reason or ways to solve it.

Was this ok in earlier versions of graphview?

Hopefully Mike knows, as I too have never had much luck with zooming. I have instead gone with changing the size of the nodes and the space between them.

I am interested to help if someone can put in a working code for me to test out.

It might even have to do with the shadowing on the container that is the node. I have taken to using a slider and resizing the container/node with the slider. It seems like the InteractiveViewer is the issue.

I am closing this ticket. Hoping this is not relevant anymore
