在Flutter中构建窗口小部件之前，如何获取用户的首选语言? [英] How to get the preferred language of a user before building a widget in Flutter?

问题描述

我想知道用户的首选语言是什么(在Android上，这是用户在Android设置中定义的语言).我想获得这个价值.例如"fr"，"en"，"ja"，或者也许是"fr-CA"，"en-US"，"ja-JP".

I'd like to know what is the preferred language of the user (on Android that's something that the user defines in the Android's settings). I'd like to get this value. For example "fr", "en", "ja", or maybe "fr-CA", "en-US", "ja-JP".

我只想获取用户首选的语言，以便以用户喜欢的语言在应用程序中构建一个小窗口小部件. 这应该很简单，但是我找不到解决方法.

I just want to get the user preferred language to build a small widget within the app in the language the user prefers. This is something that should be very simple but I couldn't find a way to do this.

例如，在Android上的Java中，您可以

For example, on Android, in Java, you can do

Locale.getDefault().getLanguage() 

这为您提供了用户的首选语言. Flutter中的等效功能是什么?

And that gives you the preferred language of the user. What is the equivalent in Flutter?

推荐答案

import 'dart:ui';

....
....

print(window.locale.languageCode);

如果是英语，它将输出en，如果是德语de，等等.

If english it will output en, if german de etc.
