WhatIfHasExtras

An expression for invoking whatIf lambda when the Activity's intent extras is not null and not empty.

var foo: String? = null
this@MainActivity.whatIfHasExtras {
  foo = "${it.getString("foo")}"
}

And we can handle the null case.

   whatIfNot = { log("intent extras is null or empty.") }
)

We can execute a single lambda if the string is not null and not empty.

val nullableString: String? = "NotNullOrEmpty"
nullableString.whatIfNotNullOrEmpty { 
  log("$it is not null and not empty")

Or we can handle the null or empty case.

nullableString.whatIfNotNullOrEmpty(
  whatIf = { nullableString = it },
  whatIfNot = { nullableString = "NullOrEmpty" }
)

nullableIntList.whatIfNotNullAs<List<Int>> {
