<!-- Thank you for using Flutter! If you are looking for support, please check out our documentation or consider asking a question on Stack Overflow: * https://flutter.dev/ * https://api.flutter.dev/ * https://stackoverflow.com/questions/tagged/flutter?sort=frequent If you have found a bug or if our documentation doesn't have an answer to what you're looking for, then fill out the template below. Please read our guide to filing a bug first: https://flutter.dev/docs/resources/bug-reports --> ## Use case <!-- Please tell us the problem you are running into that led to you wanting a new feature. Is your feature request related to a problem? Please give a clear and concise description of what the problem is. Describe the alternative solutions you've considered. Is there a package on pub.dev/flutter that already solves this? --> Some applications use keyboard events that do not have a specified `key` or `code` field and must interpret the keyboard event's `keyCode` field. ## Proposal <!-- Briefly but precisely describe what you would like Flutter to be able to do. Consider attaching something showing what you are imagining: * images * videos * code samples Does this have to be provided by Flutter directly, or can it be provided by a package on pub.dev/flutter? If so, maybe consider implementing and publishing such a package rather than filing a bug. --> Expose html KeyboardEvent's keyCode field in RawKeyEventDataWeb class
