can anybody please explain the meaning of the statement, val image = +imageResource(R.drawable.header) what is the use of "+" sign and hwy to use it?

It's a use of operator overloading, in this case the

unaryPlus

operator. https://kotlinlang.org/docs/reference/operator-overloading.html

If i remove + operator here what will be its significance? val image = imageResource(R.drawable.header)

The first one is equivalent to this:

val image = imageResource(R.drawable.header).unaryPlus()

The 2nd is just:

val image = imageResource(R.drawable.header)

yes i am asking the same what makes val image = imageResource(R.drawable.header).unaryPlus() difference from val image = imageResource(R.drawable.header) ?

The first calls

unaryPlus

, the 2nd doesn't...? I am not sure what your question is.

probably the question is what unaryPlus() is doing

yes

you have to find where the operator overload is defined

okay

Yo should be able to ctrl-click on the "+" sign like on a normal method call and Intellij should take you there

i got it

Looks like #compose
