<!-- 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 our 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 alternative solutions you've considered. Is there a package on pub.dev/flutter that already solves this? --> ## Proposal <!-- Briefly but precisely describe what you would like Flutter to be able to do. Consider attaching images showing what you are imagining. 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. -->
