firebase - 如何在 Flutter 中为 Firebase 身份验证手动触发 onAuthStateChanged？

Question

我有一个围绕 StreamBuilder 构建的应用程序聆听 FirebaseAuth.instance.onAuthStateChanged

  return new StreamBuilder<FirebaseUser>(
  stream: FirebaseAuth.instance.onAuthStateChanged,
  builder: (BuildContext context, snapshot) {
    if (snapshot.connectionState == ConnectionState.waiting) { ...

我正在尝试重新加载用户并在验证电子邮件时使用 onAuthStateChanged 进行接收。 User.reload() 对 StreamBuilder 不够用.这是一个与此类似的问题 onAuthStateChanged doesn't get called when email is verified in flutter

我认为一个解决方案是强制注销和登录，但我不知道如何做到这一点 - 例如第二步，再次登录触发onAuthStateChanged。

  _auth.signOut(); //sign out and immediate sign in
  final FirebaseUser user = await _auth.signIn----( //which signin function?

您是否尝试过刷新身份验证 token ？
