Expression body syntax is preferable here
Reports return expressions (one-liners or when) that can be replaced with expression body syntax.
Expression body syntax is recommended by the style guide.
Convert to expression body quick-fix can be used to amend the code automatically.
Example:
fun sign(x: Int): Int {
return when { // <== can be simplified
x < 0 -> -1
x > 0 -> 1
else -> 0
}
}
After the quick-fix is applied:
fun sign(x: Int): Int = when {
x < 0 -> -1
x > 0 -> 1
else -> 0
}
