如何在单一语言环境应用程序上本地化 showDatePicker？

Question

我有一个仅适用于非英语语言环境的应用程序，因此它在 Text 对象中包含硬编码字符串。我正在尝试本地化 showDatePicker()

如果我尝试传递localizationsDelegates: [GlobalMaterialLocalizations.delegate]给 MaterialApp，则会出现异常。

如果我尝试传递locale: const Locale("es")给 showDatePicker 而不传递localizationDelegates给MaterialApp，则会出现异常。

Answer 1

I've solved it.

Pass these arguments to the materialApp:

localizationsDelegates: const [
  GlobalMaterialLocalizations.delegate,
  GlobalWidgetsLocalizations.delegate, // ONLY if it's a RTL language
],
supportedLocales: const [
  Locale('fr', 'FR'), // include country code too
],

And since the locale is already defined, it's not necessary to pass it to showDatePicker.
