TypingIndicator
fun TypingIndicator(modifier: Modifier = Modifier, contentDescription: String = "", color: Color = MaterialTheme.colorScheme.onSurfaceVariant)
Three dots pulsing in turn, for "a reply is being written", usually inside a chat bubble. It reads as composing rather than loading. The wave runs in the draw phase without recomposing, and the dots hold still when the system reduces motion and in previews.
Parameters
contentDescription
announced politely to screen readers; blank hides the indicator from them, for example when the enclosing bubble already announces the pending reply.
