I am facing the same issue. Any solution?

I have a potential fix in #117, please confirm if that fixes the issue for your graphs.

Hi

Same issue. from time to time, nodes are stuck and flickering from bottom left to top right or bottom right to top left.

Thanks

I think that the flickering comes from attraction computation when each step generates in turn a large positive offset and a large negative offset... No time to fix, but FWIW, I noticed that the system is sensitive to initial placement.
Placing all nodes in a circle works for me

double radius = 100;
double angle = 0;
Offset center = Offset(200, 200);
graph.nodes.forEach((node) {
  node.position = center + Offset(radius * cos(angle), radius * sin(angle));
  angle += (2 * pi) / graph.nodes.length;
});

Please test it out in v1.5.0. Not sure if it has improved or not

Hey
Sorry stupid question, I am new to dart.
pub exposes 1.2.0 from 2 years ago.
How does one get 1.5.0?

[nabil6391]

Apologies, I was still fixing some analyse codes. You should find it now

[ngx472]

SOmething is strange. When I revert to 1.2 to reproduce, I still see the new signature for
FruchtermanReingoldAlgorithm(this.configuration, {this.renderer}) {
as if the 1.2 was in fact the 1.5...

The 1.2 now breaks my code completely. Maybe I have something wrong

BTW the pub label on https://github.com/nabil6391/graphview still says 1.2

[ngx472]

Reverted to version 1.2 from github downloaded as a package and referencing from my code now.
(I don't know what was wrong with my pub get 1.2)
Version 1.5 has so many changes it breaks my layout, so I will test later.
Thanks
