+// ADDING A NEW STRING
+//
+// If you (someone contributing to the Flutter framework) want to add a new
+// string to the MaterialLocalizations object (e.g. because you've added a new
+// widget and it has a tooltip), follow these steps:
+//
+// 1. Add the new getter to MaterialLocalizations below.
+//
+// 2. Implement a default value in DefaultMaterialLocalizations below.
+//
+// 3. Add a test to test/material/localizations_test.dart that verifies that
+//    this new value is implemented.
+//
+// 4. Update the flutter_localizations package. To add a new string to the
+//    flutter_localizations package, you must first add it to the English
+//    translations (lib/src/l10n/material_en.arb), including a description, then
+//    you must add it to every other language (all the other *.arb files in that
+//    same directory), including a best guess as to the translation, e.g.
+//    obtained by optimistic use of Google Translate
+//    (https://translate.google.com/). There is a README file with further
+//    information in the lib/src/l10n/ directory.
+//
+// 5. If you are a Google employee, you should then also follow the instructions
+//    at go/flutter-l10n. If you're not, don't worry about it.
