 3. New translations will be parsed but have no effect.

+If you use dependency injection, then you can create a new overridden instance using `AppLocaleUtils`:
+
+```dart
+Translations t2 = AppLocaleUtils.buildWithOverridesSync(
+  locale: AppLocale.en,
+  fileType: FileType.yaml,
+  content: r'''
+onboarding
+  title: 'Welcome {name}'

+String a = t2.onboarding.title(name: 'Tom'); // "Welcome Tom"
+```
