I created a helper flow where based on the condition Return card should return the text value as true/false.
But every time when I am testing this helper flow it is returning nothing.
Helper flow:
I tested running this helper flow from the parent workflow also there also I am getting an empty value.
Parent workflow card:

It isn't returning anything the flow is stopping on the Continue If. -1 is_not "greater than" -1 they are "equal". Nothing would execute to the right of the Continue If in this scenario.
The "message" on the continue if cards is just meant to be informative. It cannot be passed anywhere as the flow will stop when it occurs. So for example lets say "List Length" check is happening. If the length is not greater than 0 you want the flow to stop. The message would be "List empty" so a quick glance tells you why.
With what it appears you want to do an "Assign If" might be a better option. You can assign one value if the comparison is "true" and another value if "false".
