Code Review
This pull request fixes an issue where the DropdownMenu width was not calculated correctly when a label was provided via decorationBuilder. The change introduces effectiveLabel to consider InputDecoration.label and InputDecoration.labelText from the decorationBuilder when calculating the menu's preferred width. The implementation is correct and well-tested with two new widget tests that cover both label and labelText cases. The changes look good and address the reported issue effectively.
