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.weight(
    weight: @FloatRange(from = 0.0, fromInclusive = false) Float,
    fill: Boolean = true
): Modifier

Size the element's width proportional to its weight relative to other weighted sibling elements in the ButtonGroup. The parent will divide the horizontal space remaining after measuring unweighted child elements and distribute it according to this weight. When fill is true, the element will be forced to occupy the whole width allocated to it. Otherwise, the element is allowed to be smaller - this will result in ButtonGroup being smaller, as the unused allocated width will not be redistributed to other siblings.
