ButtonGroupScope

fun Modifier.animateWidth(interactionSource: InteractionSource): Modifier

Specifies the interaction source to use with this item. This is used to listen to events and animate growing the pressed button and shrink the neighbor(s).

fun Modifier.minWidth(minWidth: Dp = ButtonGroupDefaults.MinWidth): Modifier

Specifies the minimum width this item can be, in Dp. This will only be used if distributing the available space results in a item falling below its minimum width. Note that this is only used before animations, pressing a button may result on neighbor button(s) going below their minWidth. See also Modifier.weight

fun Modifier.weight(
    weight: @FloatRange(from = 0.0, fromInclusive = false) Float
): Modifier

ButtonGroup uses a ratio of all sibling item weights to assign a width to each item. The horizontal space is distributed using weight first, and this will only be changed if any item would be smaller than its minWidth. See also Modifier.minWidth.
