我正在使用 Flow 最新版本（0.75.0），但我找不到abort在没有 Flow 抱怨的情况下覆盖该方法的方法

interface Inter {
  abort(): void;
  done(): void;
}

class Hello implements Inter {
   abort() {}
   done(){}
}

let h = new Hello();

h.abort = function() {}

错误如下。

../-:15: h.../ abort = function() {}
           ^ Cannot assign function to `h.abort` because property `abort` is not writable.
