is there an away to avoid the assertion operator to make the value type not null on the following case?

if (key in map) {
        val value = map[key]!!
    }

If I remove the assertion operator, the type of the

value

will be

?

if (key in map) {
    val value = map.getValue(key)
}

or

val value = map[key]
if (value != null) {
    // ...
}

Cool, I didn't knew about the

getValue

method. It works like a charm here. Thanks 😃

Also to make it more explicit with custom error message:

val value = map[key] ?: error("My custom error")
