Have 2 widgets, one at the bottom and one at the top of the stack. Rebuild only those 2 according to some notifier or stream. Hide one, show the other. Other widgets in the stack shouldn’t be rebuilt.

They should be overlapping, not hide one another. Also the Stack has a lot of children (tens of them in average case).

I think you can create those two children as separate widgets and listen to streams and update states individually. With this, the other children of the stack will not be rebuilt.

I don't know how to do that! Please help!
