Question

我想将tr标签添加到Flutter本地化部分。我是尽管有支持Tr的错误。错误是跟随;错误：元素类型为'Locale（其中Locale在 C：\ Users \ StatTark \ AppData \ Roaming \ Pub \ Cache \ hosted \ pub.dartlang.org \ intl-0.16.1 \ lib \ src \ locale.dart）' 不能分配给列表类型'区域设置（其中区域设置在 C：\ flutter \ bin \ cache \ pkg \ sky_engine \ lib \ ui \ window.dart）'。
错误：无法实例化抽象类。（位于[ajanda] lib \ pages \ mainmenu.dart：36的instantiate_abstract_class）

我不知道我是否在使用中犯了一个错误，如果您能提供帮助，我会很高兴。

您可以尝试/测试的一些建议，请参见下文。

将[Locale('en','US'),Locale('tr','')],替换为[Locale('en'),Locale('tr')],
首先初始化受支持的语言环境列表，并相应地使用它。

// init before build  
final List<Locale> appSupportedLocales = [
  Locale('en'),
  Locale('tr')
];

// ...
// then use it like this   
supportedLocales: appSupportedLocales,
