If you mean `!`, then it basically translates to `not`. So if you place this before your boolean expression, it will return true only if the conditions of the expression are not met. — ThePerplexedOne, Oct 08 '19 at 15:30
if it says bl = false it means reader contains("auto_load_more_enabled") ?? — MdSalehGh, Oct 08 '19 at 15:32

You are looking at a negation operator, the ! placed in from of a boolean expression inverse the result.

! is the NOT (negation) logical operator.

It transform a false to true and true to false.
