Pattern: Unsafe call on nullable type
Issue: -
Reports unsafe calls on nullable types. These calls will throw a NullPointerException in case the nullable value is null. Kotlin provides many ways to work with nullable types to increase null safety. Guard the code appropriately to prevent null pointer exceptions.
Example of incorrect code:
fun foo(str: String?) {
println(str!!.length)
}Example of correct code:
fun foo(str: String?) {
println(str?.length)
}
