How to create custom widget

[vd3d]

Hi,

I'm currently using this widget: https://pub.dev/packages/flutter_treeview

And I wish to add the possibility to move nodes, ie. change the order, change the parent etc.
So, do you think I can do such with your library, so mixing your library and the treeview library? (Or I must recreate a complete new one).

If yes, can you provides some instructions?

Thanks
