Flutter webview_flutter Localization

Question

How to change the language of copying/cutting?

The following code has been added to the main file, but it does not take effect in WebViewWidget

localizationsDelegates: const [
              RefreshLocalizations.delegate,
              GlobalCupertinoLocalizations.delegate,
              GlobalMaterialLocalizations.delegate,
              GlobalWidgetsLocalizations.delegate,
              FallbackCupertinoLocalisationsDelegate()
            ],
            locale: const Locale('zh'),
            supportedLocales: const [
              Locale('zh', 'CN'),
            ]localizationsDelegates: const [
              RefreshLocalizations.delegate,
              GlobalCupertinoLocalizations.delegate,
              GlobalMaterialLocalizations.delegate,
              GlobalWidgetsLocalizations.delegate,
              FallbackCupertinoLocalisationsDelegate()
            ],
            locale: const Locale('zh'),
            supportedLocales: const [
              Locale('zh', 'CN'),
            ]
