如何在 stless 和 staful class flutter 之外傳遞上下文

Question

我想在常量文件中使用上下文，例如

class StatusCodes {  
    static Map<int, String> overTimeCancelResponse = {
    0: "OverTime request Cancel Successfully",
    1: "Error Cancelling OverTime Request",
  }; 
}

or 
   
   class StatusCodes {
   static Map<int, OverTimeResponses> overTimeResponse = {
   0: OverTimeResponses(
      "Overtime Request Submitted Successfully",
       Colours.green,
     ),
   };
}

我正在使用語言文件將 eng 更改為像這樣的不同語言，例如

class StatusCodes {  
    static Map<int, String> overTimeCancelResponse = {
    0: S.0f(context).cancel_request,
    1: S.0f(context).error,
  }; 
}

但我無法在這里使用上下文

Answer 1

您可以創建一個 Map function function，通過參數傳遞上下文並返回您的 Z1D78DC15ED5141214E5AEZ22

請參閱下面的代碼

class StatusCodes {
  Map<int, String> overTimeCancelResponse(BuildContext context) {
   return {
     0: "OverTime request Cancel Successfully", // you can pass a value with context here
     1: "Error Cancelling OverTime Request",
  };
 } 
}

Answer 2

也許你不應該，但如果你“必須”這是你能得到的最接近的：

class StatusCodes {

    static Map<int, String> getOverTimeCancelResponse(BuildContext context) {
      // Do something with context
      // ....
      // build your new "overTimeCancelResponse"
      return newOverTimeCancelResponse;
    }
}

不能在 static 變量中使用BuildContext （或任何其他變量）。
