Spaces on both sides of the double slash (//) that begins an end-of-line comment

[egor-n]

The JetBrains Kotlin Coding Conventions suggest placing a space after //:

The Android Kotlin Style guide suggests placing a space before and after the double slash (//) if it begins an end-of-line comment:

---

Ktlint should flag lack of spaces around //.

Correct:

// comment
var debugging = false // comment
var debugging = false // comment//word

Incorrect:

//comment
var debugging = false// comment
var debugging = false //comment
var debugging = false//comment

It should not only flag it but also autocorrect it.
