 - **Stocks** The [stocks](stocks) demo shows how one might structure
   an application with several screens.
+
+Note on Gradle wrapper files in `.gitignore`:
+
+Gradle wrapper files should normally be checked into source control.
+The example projects don't do that to avoid having several copies of the
+wrapper binary in the Flutter repo. Instead, the Gradle wrapper is
+injected by Flutter tooling, and the wrapper files are .gitignore'd to
+avoid making the Flutter repository dirty as a side effect of running
+the examples.
