## Description This PR adds `InputDecorator.maintainLabelSize` (similar to `InputDecorator.maintainHintSize`) to allow the label to be used in the intrinsic width calculation (if could be used for the intrinsic height calculation later if needed). I opted for this flag (and defaulting to false) because changing the default calculation would probably break various usages. See https://github.com/flutter/flutter/issues/178099#issuecomment-3496116095 for why this change will be helpful to simplify and fix DropdownMenu implementation. ## Before The label might be cut off: <img width="126" height="71" alt="Screenshot 2025-11-05 at 20 16 43" src="https://github.com/user-attachments/assets/61d9f817-5c58-43f9-9307-976f9c124ec7" /> ## After The label is entirely visible because it is part of the intrinsic width calculation: <img width="126" height="71" alt="Screenshot 2025-11-05 at 20 16 09" src="https://github.com/user-attachments/assets/47360e17-3cde-4f05-8a6b-cc9e86644ffc" /> ## Related Issue Fixes [DropdownMenu menu panel does not close when pressing ESC and requestFocusOnTap is false](https://github.com/flutter/flutter/issues/177993) Part of https://github.com/flutter/flutter/issues/123797 ## Tests - Adds 4 tests. - Updates 1 non-related test where I spotted some nits.
