Hi Thanks for the question!

For now the third party plugin flutter_localizations is not ported to UIWidgets yet. As the result, currently we don't support its relevant functionalities.

However, as a quick work-around, you can directly change the value of pasteButtonLabel, cutButtonLabel, etc. inside the material/material_localizations.cs file to make them Chinese

@zhuxingwei 你好，我看之前您在1.5版本写过一个语言国际化的demo，2.0可以也写一个么？

Hi Thanks for the reply!

Could you please share me a link of this localization demo you mentioned and I will have a look then. Thanks !
