Code Review
This pull request adds the errorBuilder property to DropdownMenuFormField, allowing for custom error widget display, which aligns it with other form fields. The implementation is sound and the accompanying tests are thorough, covering the new functionality and updating existing tests to reflect the refactoring of decoration properties. I have one suggestion to simplify the decoration builder logic for better readability.

Can we implement the errorBuilder to the FormField as well? I supose this parameter has been added only for the FormField implementations to use it Edit: |
