3.FallbackCupertinoLocalisationsDelegate类

import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';

class FallbackCupertinoLocalisationsDelegate
    extends LocalizationsDelegate<CupertinoLocalizations> {
  const FallbackCupertinoLocalisationsDelegate();

  @override
  bool isSupported(Locale locale) => true;

  @override
  Future<CupertinoLocalizations> load(Locale locale) =>
      DefaultCupertinoLocalizations.load(locale);

  @override
  bool shouldReload(FallbackCupertinoLocalisationsDelegate old) => false;
}
