getMessageBubbleShape
fun getMessageBubbleShape(cornerRadius: Dp, isSender: Boolean, hasSamePrev: Boolean = false, hasSameNext: Boolean = false, groupedCornerRadius: Dp = 4.dp): CornerBasedShape(source)
Returns a CornerBasedShape for a message bubble based on its position in a sequence.
Standalone bubbles are fully rounded; consecutive bubbles from the same sender flatten only the corners facing each other (to groupedCornerRadius) so a run reads as one visual group, matching the M3 conversation pattern.
Parameters
cornerRadius
The base corner radius for the bubble.
isSender
Whether the message was sent by the local user.
hasSamePrev
Whether the previous message in the list is from the same sender.
hasSameNext
Whether the next message in the list is from the same sender.
groupedCornerRadius
The reduced radius used on corners adjacent to a same-sender neighbor.
