-// TODO : Fix localization instructions
-// ADDING A NEW STRING
-//
-// If you (someone contributing to the Stream Chat Flutter) want to add a new
-// string to the StreamChatLocalizations object (e.g. because you've added a new
-// widget and it has a tooltip), follow these steps:
-//
-// 1. Add the new getter to StreamChatLocalizations 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/en.json), including a description.
-//
-//    Then you need to add new entries for the string to all of the other
-//    language locale files by running:
-//    ```
-//    dart dev/tools/localization/bin/gen_missing_localizations.dart
-//    ```
-//    Which will copy the english strings into the other locales as placeholders
-//    until they can be translated.
-//
-//    Finally you need to re-generate lib/src/l10n/localizations.dart by running:
-//    ```
-//    dart dev/tools/localization/bin/gen_localizations.dart --overwrite
-//    ```
-//
-//    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.
-//
-// UPDATING AN EXISTING STRING
-//
-// If you (someone contributing to the Flutter framework) want to modify an
-// existing string in the MaterialLocalizations objects, follow these steps:
-//
-// 1. Modify the default value of the relevant getter(s) in
-//    DefaultMaterialLocalizations below.
-//
-// 2. Update the flutter_localizations package. Modify the out-of-date English
-//    strings in lib/src/l10n/material_en.arb.
-//
-//    You also need to re-generate lib/src/l10n/localizations.dart by running:
-//    ```
-//    dart dev/tools/localization/bin/gen_localizations.dart --overwrite
-//    ```
-//
-//    This script may result in your updated getters being created in newer
-//    locales and set to the old value of the strings. This is to be expected.
-//    Leave them as they were generated, and they will be picked up for
-//    translation.
-//
-//    There is a README file with further information in the lib/src/l10n/
-//    directory.
-//
-// 3. 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.
