Why is there a `String?.isNullOrBlank()` but there is no `String?.isNotNullOrBlank()`  while there is a `String.isBlank()` and `String.isNotBlank()`

If there was, shouldn't it really be called `String?.isNotNullButBlank()`

I see.. then it should be `isNotNullNorBlank`

Hard to negate that, huh? Probably why it doesnt exist?

yep and `!nullableStringVariable.isNullOrBlank()` does what (I assume) you are trying to do

strictly speaking, you could potentially instead do `if (maybeString?.isBlank() == false)`

I often wish for a function that replaces `!isNullOrBlank()`, it’s pretty common requirement and negating manually is equally confusing to `isNotNullNorBlank`

I’d definitely use `has[NonWhitespace]Content` or something similar

in our Java projects we use overloaded (for String, List, Map, Array, ...)  `hasContent` and `noContent` with an optional type-specific `trim` parameter (e.g. for String if `trim` is `true` then `hasContent` is `s != null &amp;&amp; !s.trim().isEmpty`)
