Flutter Web 的 "compute()" 是否在它自己的线程或 web worker 上工作,或者它是如何工作的?

Does Flutter Web's "compute()" work on it's own thread or web worker, or how does it work?

如果我这样做,例如:

FutureBuilder(
   initialData: null,
   future: compute(expensiveParsingOperation, data),
   builder: (context, snapshot) {
       if(!snapshot.hasData){
          // This doesn't spin (frozen).  The entire UI is janked until the expensive operation future completes.
          CircularProgressIndicator(); 
        }else {  
             Container(); 
         } 
});

我希望上面的代码将 expensiveParsingOperation 函数发送给网络工作者或其他东西,而不是让主线程卡顿,但这不是我观察到的情况。

compute此时在网络平台上什么都不做 见 https://github.com/flutter/flutter/issues/33577
