解开（c）=＆gt; C（）
我有一个问题：（c）=＆gt;我发现在这里 ：//stackoverflow.com/questions/51227165/what-does-foreachc-c-mean-in-dart“> where 。 我知道它可以定义一个具有未型参数的匿名函数c。但是它似乎是指
- 无参数的未定义函数c（），即具有与初始匿名函数的参数相同的名称，
- 或者是其自己的参数C，就好像此非常参数是无参数的未定义函数本身。
我很确定我没有正确地做到这一点，而且我错过了重点，但是任何提示都会有助于解开（c）和c（），并掌握功能最终的真实作用。
I have an issue with : (c) => c() which I found here and there.
I understand that it defines an anonymous function with an untyped parameter, c. But then it seems to refer
- to a parameter-free undefined function c(), i.e. having the same name as the parameter of the initial-anonymous function,
- or to its own parameter c as if this very parameter were a parameter-free undefined function it-self.
I'm pretty sure that I did not get it right and that I miss the point, but any hint would help to untangle (c) and c(), and grasp what the function ends up doing for real.

这是一个匿名功能，可以获取名为
c的东西。然后调用它的收到的函数好像是一个函数。这意味着编译器发现它是是没有参数的函数，或者是dynamic。否则，编译器会抱怨。因此，英语：一个名为
c的参数的匿名函数。该参数的类型是“无参数的函数”。然后调用它刚刚获得的函数。It is an anonymous function that gets something named
c. It then calls what it gets as if it were a function. That implies that the compiler figured out that it either is a function with no parameters, or it is adynamic. Otherwise the compiler would have complained.So in english: an anonymous function that has a parameter named
c. The type of that parameter is "function with no parameters". It then calls the function it just got as argument.
