Sometimes the developer will not fully follow material specs and create custom looking buttons.

mvivo@ faced it(his screenshot is in attachment:
"I used a plain ButtonStyle because border in the other implementations cannot be null
This is my button
style = ButtonStyle(
                    backgroundColor = MaterialTheme.colors().primary,
                    contentColor = MaterialTheme.colors().onSurface,
                    shape = RoundedCornerShape(16.dp),
                    border = if (selected) Border(color = Color.White, width = 2.dp) else null
                )
Couldn't use ContainedButtonStyle because it has no border, couldn't use OutlinedButtonStyle because border cannot be null, and neither TextButtonStyle because of all the above"
