如何从Firebase身份验证获取令牌

Question

我需要在进行身份验证时从Firebase获取令牌，然后将令牌转移到后端。我有几种情况下auth。我还没有使用令牌。下一步应该怎么做？

final FirebaseAuth _firebaseAuth = FirebaseAuth.instance;
  Future<FirebaseUser> getCurrentUser() => _firebaseAuth.currentUser();

  Future<AuthResult> signInWithGoogle() async {
    final authentication = await GoogleAuth().signIn();
    final credential = GoogleAuthProvider.getCredential(
      accessToken: authentication.accessToken,
      idToken: authentication.idToken,
    );
    return _firebaseAuth.signInWithCredential(credential);
  }

Future<AuthResult> signInWithEmail(String email, String password) {
    return _firebaseAuth.signInWithEmailAndPassword(
      email: email,
      password: password,
    );
  }
