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?

[diesieben07]

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

[Jay M]

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

[diesieben07]

The first one is equivalent to this:
val image = imageResource(R.drawable.header).unaryPlus()
The 2nd is just:
val image = imageResource(R.drawable.header)

[Jay M]

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

[diesieben07]

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

[Dias]

probably the question is what unaryPlus() is doing

[Dias]

which you can look at the source

[Jay M]

yes

[Matteo Mirk]

you have to find where the operator overload is defined

[Jay M]

okay

[diesieben07]

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

[Jay M]

i got it

Looks like #compose
