Negated call can be simplified

Reports negation isEmpty() and isNotEmpty() for collections and String, or isBlank() and isNotBlank() for String.

Using corresponding functions makes your code simpler.

The quick-fix replaces the negation call with the corresponding call from the Standard Library.

Example:

fun main() { val list = listOf(1,2,3) if (!list.isEmpty()) { // do smth } }

After the quick-fix is applied:

fun main() { val list = listOf(1,2,3) if (list.isNotEmpty()) { // do smth } }
