The “Flutter” name and the Flutter logo (the “Flutter Marks”) are trademarks owned by Google and are not included within the assets licensed under the Creative Commons Attribution 4.0 International License. Google grants you a non-transferable, non-exclusive, royalty-free limited license to use the Flutter Marks subject to your compliance with the Flutter Brand Guidelines. Except as set forth above, nothing herein grants or should be deemed to grant to you any right, title or interest in or to the Flutter Marks.
As noted above, Google owns the Flutter trademarks, but we license them so they can be used by the developer community to support the Flutter SDK, including through training materials and other community content.
At the same time, it’s important to make sure that people don’t use the marks in ways that could cause confusion or otherwise misuse the marks, so we have prepared brand guidelines that describe the allowed uses of the marks. Our goal in protecting the Flutter trademarks is to benefit the entire community by ensuring that the marks are only used in ways that are consistent with Google’s mission to provide a free and open source SDK.
