+
+## Contributor License Agreement
+
+Contributions to this project must be accompanied by a Contributor License
+Agreement (CLA). You (or your employer) retain the copyright to your

+contributions as part of the project. Head over to
+<https://cla.developers.google.com/> to see your current agreements on file or

+
+You generally only need to submit a CLA once, so if you've already submitted one
+(even if it was for a different project), you probably don't need to do it
+again.
+
+## Code Reviews
+
+All submissions, including submissions by project members, require review. We
+use GitHub pull requests for this purpose. Consult
+[GitHub Help](https://help.github.com/articles/about-pull-requests/) for more

+
+  * [Dart style guide](https://dart.dev/guides/language/effective-dart/style)

+
+## File headers
+
+All files in the Dart project must start with the following header; if you add a
+new file please also add this. The year should be a single number stating the
+year the file was created (don't use a range like "2011-2012"). Additionally, if
+you edit an existing file, you shouldn't update the year.
