Description:

This attempts to cache MinSize values of widgets to provide for faster lookups by avoiding recalculations when nothing has changed. I think it feels quite a bit faster when just using fyne_demo. Placebo?

Supersedes #4681

Checklist:

  • Tests included.
  • Lint and formatter run with no errors.
  • Tests all pass.

Where applicable:

  • Public APIs match existing style and have Since: line.

We should likely fix this as it kind of goes against the idea of refreshing a widget when it changes state. Sounds like a bug but it isn't new behaviour to this PR so I'll let it slide for now.

I thought, that I had added some sort of minSize cache back in the days when I worked on the walkers, didn’t I?
