I have a lambda and I’m trying to have it return null from within an if statement; but it seems that it just exits the if and moves on to the last line: { .....some lines.... if (condition) { null } ..... final value }

[Dominaezzz]

You'll need to do if (condition) { null } else { ..... final value } I think.

Or use return@foo null.

👍🏼 Thanks. That got me working.

the different syntax between functions and lambdas always gets me a little bit.

Yeah I dont blame you, would be nice of the compiler could flag if(condition) { null } otherValue as failing to compile with a compiler error something along the lines of

if(...) { null }, using null without a parent statement is illegal in this context. Either assign the expression to a value, return it, or simply invoke the condition.

is there no intelliJ inspection for same as suspicious? I know that if(condition) is a problem because condition may have side effects, but if(ANY_EXPR) { CONSTANT_EXPR } is odd even if ANY_EXPR has a side effect when CONSTANT_EXPR is unused --and of course, in the overwhelming majority of cercomstances, people use ANY_EXPR as being ref-transparent, so the whole thing is almost certainly not what the programmer wanted.
