0xFF0000FF An integer literal does not conform to the expected type kotlin.Int

Question

Why doesn't this work:

var color: Int = 0xFF0000FF

and why do I have to call toInt()

var color: Int = 0xFF0000FF.toInt()

Loveless

because 0xFF0000FF is not an integer already, so you have to convert it to an integer if you want your color variable to be that type. – Isabelleisac

@dubstylee What if I have the same, but for "long" type? converting to long won't help, no? 0xFF0000FFFF0000FF , for example... – Mccue

I am using boolean an in my case I was using this way with same error

var shouldShowOnBoarding by remember { mutableStateOf(true) }

Previous import was

import androidx.compose.runtime.Composable

Then I changed it to

import androidx.compose.runtime.*
