I found flowcanvas is flexible and powerful, and it has some features that other plugins don’t have, e.g. data binding, reflect any custom data type that not reference Unity API. I want to learn it and serach myself before asking, but I can’t find the seach box.
I have tried to use google with parameter site://https://flowcanvas.paradoxnotion.com/forum but it didn’t work fine, e.g. google “runtime site://https://flowcanvas.paradoxnotion.com/forum” will link to the 8th page, but that page have no topic about “runtime”, goolge returns an old cache.
