Expected behavior? Why?

// Doesn't work, it keeps the size over the time.
SomeComponent(
    shape = RoundedCornerShape(if (someState) 8.dp else 30.dp),
)

// Work, size is changing
SomeComponent(
    shape = if (someState) RoundedCornerShape(8.dp) else RoundedCornerShape(30.dp),
)

maybe you have to keep the size in a

mutableStateOf{}

to trigger the corner recomposition

yeah,

someState

is a

by remember { mutableStateOf(...) }

. Even using a dp size as state it doesnt work.

// Doesn't work, it keeps the size over the time.
SomeComponent(
    shape = RoundedCornerShape(someSizeState),
)

How are you using the shape inside SomeComponent?

but I”m not sure the

if

is triggered again inside the parameters of the shape, maybe you can use

produceState

to create a

cornerSize

var that will recompose

SomeComponent

@Zoltan Demant SomeComponent it is indeed the Material button

@Tgo1014 yeah, not sure if it is a general issue or it is related to the fact that RoundedCournerShape is changing internally, so compose doesn't know that fact is happening so it is not rerender
