What’s the simplest way to declare a layout with a header and a footer? Scaffold is simple but I heard it’s expensive to use.

Really? I haven't heard that before. My app uses a bunch of nested scaffolds with noticeable issues. /shruggie

If you need something similar, then I supposed you could do a Box, or a column.

Box{
Top(align(Top))
Center(fillMaxSize)
Bottom(align(Bottom))
}

or

Column{
Top()
Center(weight(1f))
Bottom()
}

I heard it once and never forgot about it 😄 because we are using a lot of Scaffold

Box are on top of each other, you’d have to know the sizes of top and bottom I think.
Column… not sure that works for a scrollable center content 🤔 maybe

I use scaffold a lot because since I draw edge to edge I like to have the contentPadding arg passed to my content.

and yeah. i def use scaffold inside of scaffolds a bunch. i wouldn't worry about it too much, but yeah like ian said. you can probably go to a column first to see if that works for you.

[Colton Idle]

i can confirm that you can def do this with a box, or column though because i do this throughout my 3 apps depending on different requirements.

Well, I already have an app performance problem, so worried about anything that contributes to the slow down 😄

[Colton Idle]

whats the profiler say about where your bottlenecks are?

It doesn’t really give anything useful, just that that recompositions take a long time
