Hi all, How can I create custom snack bar which used in scaffold? details in thread.

There exists a variant of the Snackbar composable that takes content as an argument. So you could do something like this (not a proper implementation, just an example):

SnackbarHost(it) { data ->
    Snackbar(
        backgroundColor = Color.Black,
        shape = RoundedCornerShape(12.dp),
        modifier = Modifier.padding(8.dp)
    ) {
        Row(modifier = Modifier.fillMaxWidth(), horizontalArrangement = Arrangement.SpaceBetween) {
            Row(verticalAlignment = Alignment.CenterVertically) {
                Icon(<http://Icons.Outlined.Info|Icons.Outlined.Info>, contentDescription = null, modifier = Modifier.padding(end = 16.dp))
                Text(data.message)
            }
            Icon(Icons.Default.Close, contentDescription = null, modifier = Modifier.clickable { data.dismiss() })
        }
    }
}

If you need to have multiple different looking snackbars in your application, then it gets more difficult. At least I haven't found out a way to pass custom data to the snackbar host. One way is to encode additional data in the snackbar message (e.g., "blue#some random message" and just display message after the "#" to the user ), but that is a bit hacky.
