将符号转换为字符串

将符号转换为字符串

问题描述:

有没有办法将符号转换为字符串?

Is there a way to covert a Symbol into a String?

例如,VariableMirror返回Symbols而不是字符串。有没有办法将一个Symbol转换成一个String,所以我可以打印一个类的所有变量名。

For instance, a VariableMirror returns Symbols instead of Strings. Is there a way to convert a Symbol into a String, so I can print all the variable names of a class?

MirrorSystem.getName()

import 'dart:mirrors';

void main() {
  var sym = new Symbol('test');
  print(MirrorSystem.getName(sym));
}



此输出:

This outputs:


test
