I am trying to make toolbar without menu icon.

@Preview
@Composable
fun MyToolbar() {
    Text(
        text = "My Toolbar",
        fontWeight = FontWeight.Bold,
        fontSize = 20.sp,
        modifier = Modifier.background(MaterialTheme.colors.primary).height(56.dp).fillMaxWidth(),
        textAlign = TextAlign.Left,
        color = Color.White
    )
}

I decided to use

Text

, but it doesn't want to align left

Add

.wrapContentWidth(Alignment.Start)

to the end of your modifiers
