RefreshLocalizations class

Implementation of localized strings for the ClassicHeader,ClassicFooter,TwoLevelHeader

Supported languages:now only add Chinese and English If you need to add other languages,please give me a pr

Sample code

To include the localizations provided by this class in a MaterialApp, add RefreshLocalizations.delegates to MaterialApp.localizationsDelegates, and specify the locales your app supports with MaterialApp.supportedLocales:

new MaterialApp(
  localizationsDelegates: RefreshLocalizations.delegates,
  supportedLocales: [
    const Locale('en'), // American English
    const Locale('zh'), // Israeli Hebrew
    // ...
  ],
  // ...
)

If you don't have the language you need here and you want to add it, you can give me a pr.
