Error message "value is not properly set" on nullable parameters (custom widget)

[matlin76]

Has your issue been reported?

• I have searched the existing issues and confirm it has not been reported.
• I give permission for members of the FlutterFlow team to access and test my project for the sole purpose of investigating this issue.

Current Behavior

I get an error message that "the value is not properly set" even if it's a nullable parameter.
I have tried using null safety in both the constructor and in the build method but nothing helps.

Expected Behavior

I expect only the required parameters to be required.

Steps to Reproduce

• Create a new custom widget.
• Add one required parameter.
• Add one or more nullable parameters.
• Take care of the null safety in the custom code.

Use the custom widget on a page and only add value to the required parameter.

Reproducible from Blank

• The steps to reproduce above start from a blank project.

The issue also seems to be happening with custom data types.

Hi @matlin76, thank you for the bug report! This was generally there to make sure people don't forget to set values for custom widget parameters, however I agree the above issue is much worse. This will be fixed on our next release! 🙂
