'How to find where error come from in snapshot.error?

I try to use StreamBuilder and I handle error by throw snapshot.error

StreamBuilder(
  stream: stream,
  builder: (context, snapshot) {
    if (snapshot.connectionState == ConnectionState.active) {
      if (snapshot.hasError) {
        throw snapshot.error!; <- This line
      }
    }
  },
);

But It tell that This line is the one making error.

Is there any way to see where actual error come from?
