Migration guide for material localized strings

ReorderableListView's localized strings were moved from material localizations to widgets localizations. These strings were deprecated in material localizations.

ReorderableListView uses these strings to annotate its semantics actions. To apply the same annotations to ReorderableList and SliverReorderableList, they need to access these strings from widgets library.

The MaterialLocalizations strings for reorderItemToStart, reorderItemToEnd, reorderItemUp, reorderItemDown, reorderItemLeft, and reorderItemRight are deprecated and replaced by the same strings in WidgetsLocalizations.

If you use these strings in your code, you can access them from WidgetsLocalizationsinstead.

Code before migration:

MaterialLocalizations.of(context).reorderItemToStart;

Code after migration:

WidgetsLocalizations.of(context).reorderItemToStart;

If you override MaterialLocalizations or WidgetsLocalizations, make sure to remove the translations from the MaterialLocalizations subclass and move them to the WidgetsLocalizations subclass.

Code before migration:

class MaterialLocalizationsMyLanguage extends MaterialLocalizationsEn {
  // ...
  @override
  String get reorderItemRight => 'my translation';
}

Code after migration:

class MaterialLocalizationsMyLanguage extends MaterialLocalizationsEn {
  // ...
}

class WidgetsLocalizationsMyLanguage extends WidgetsLocalizationsEn {
  // ...
  @override
  String get reorderItemRight => 'my translation';
}

Landed in version: v3.10.0-2.0.pre
In stable release: 3.13.0
