Current Behavior

Hi, recently my custom widgets have been encountering this unknown error when compiling, despite there's no issue with the code itself. Sometimes with the same code that was verified before, just changing the value of a variable can cause it to fail compiling (say, a double value from 1.0 to 2.0, which can't be the cause of the error). Below are the screenshots of the error. Please look into it again, I've seen another ticket pointing to the same issue but was closed without further investigation. Thank you.

Expected Behavior

Compiling custom widget sometimes throw unknown error despite the code itself doesn't have any problem. Similarly-structured widget were compiled successfully after several tries so it's unlikely a problem from dependency.

Steps to Reproduce

1. Compile the code for my custom widgets. There are two that I haven't been able to compile, which are MonthlyAvgPriceLine (this one has been successfully compiled before, but now throwing error after changing a value) and MonthlyRevenueLine.

2. Maybe by the time you look into this, through sheer stubborness and luck I'd have been able to compile those widgets above. If so you can try changing the value of 'double interval' in MonthlyAvgPriceLine and try compiling it, that was the trigger last time.

Reproducible from Blank

funny enough, as if the bug had heard of my report and feared for its life, the widgets were compiled successfully. That being said, I haven't made any change to the code and just kept clicking "compile again" with my crossed index and middle fingers. The fact that it worked suggested there's definitely something to look into here, please don't ignore this issue. Thank you.

Hi!

What you're seeing is a known bug that has already been reported. I wasn’t able to replicate the issue on my end, and it seems to affect certain projects but not all.

In other reported cases, the workaround has been to retry compiling a few times until it goes through without the error.

If the message keeps appearing, I recommend reaching out to FlutterFlow Support via the in-app chat or at support@flutterflow.io — they can help you get rid of the error message.

Best regards
