� All files in this repository must be UTF-8. In particular, images and other binaries
� must not be checked into this repository. This is because we are very sensitive to the
� size of the repository as it is distributed to all our developers. If you have a binary
� to which you need access, you should consider how to fetch it from another repository;
� for example, the "assets-for-api-docs" repository is used for images in API docs.
� To add assets to flutter_tools templates, see the instructions in the wiki:
