Not getting a new line in kotlin text view on android studio

Question

fun SubmitOrder(view: View) {

    /* pricing of coffee */
    val total = quantity * 5
    val s: String = ("$$total.00")
    money.text = ("Total : $s\nThank You!").toString()

    //This is calling On click listener
    Toast.makeText(this, "order_Submitted", Toast.LENGTH_SHORT).show()
}

In this code, I need a new line before Thank You! in money.text but I am not getting any new line I am new in android development so, am not able to point out the mistake.

Use a custom layout or have a look at this question: https://stackoverflow.com/questions/6888664/android-toast-doesnt-fit-text — IIIIIIIIIIIIIIIIIIIIII, May 03 '21 at 07:38
Do you have any maxLines=1 or lines=1 or singleLine=true property set for the TextView? — Anju, May 03 '21 at 07:39

Let's go thru your code line by line:

val s: String = ("$$total.00")

s is a bad variable name, as it's not descriptive at all
you don't need the (braces)
the :String here is optional. In such an obvious case i would emit it.
A $ is a sign to the kotlin compiler to include the following variable. Therefore, you can't use the $ when you mean "US-Dollar". See this post on how to escape it
While ".00" works, it's no good style. I suggest you use string formatting as described here.
can be written as val s = "\$ ${String.format("%.2f", total)}"
you should wherever possible use string resources, but thats out of the scope of this answer

money.text = ("Total : $s\nThank You!").toString()

this is correct, but unnecessary verbose:
"Total : $s\nThank You!" is already a string, so there's no need to .toString()
braces are not needed
can be written as money.text = "Total : $s\nThank You!"
