Is it possible to make a column “stretchable” ? Let’s say I have 5 columns. I would like the 1st column to be attached to the screen left hand side, the 5th column to be attached to the screen right hand side. I would like to give a fixed width to the 1st, 3rd, 4th and 5th columns. But I would like to allow the 2nd column to take the remaining horizontal space. How can I do that in Compose?

You can use weight

What about the modifier

widthIn (min, max)

? Would it push the outer columns to be attached to the screen edges?

widthIn just sets the min and max width, it won't change how something is sized in relation to other components like that. You don't need constraint layout for this at all:

Row(Modifier.fillMaxWidth()) {
  Column (Modifier.width(…)) { … }
  Column (Modifier.weight(1f)) { … }
  Column (Modifier.width(…)) { … }
  Column (Modifier.width(…)) { … }
  Column (Modifier.width(…)) { … }
}
