问题出现在启动页的登录状态检查逻辑中，怀疑是获取token时触发的崩溃，代码如下：

import 'package:firebase_auth/firebase_auth.dart';
import 'package:flutter/material.dart';
import 'package:get/get.dart';

class SplashLogic extends GetxController
    with GetSingleTickerProviderStateMixin {
  late AnimationController animationController;
  late Animation<double> animation;
  bool isOnboard = false;
  EmployeeResponse employeeResponse = EmployeeResponse();
  final AuthRepository _authRepository = AuthRepository();

  @override
  void onInit() {
    super.onInit();
    animationController = AnimationController(
      duration: const Duration(seconds: 2),
      vsync: this,
    );
    animation = Tween<double>(begin: 0.8, end: 1.0).animate(
      CurvedAnimation(
        parent: animationController,
        curve: Curves.easeInOut,
      ),
    );
    animationController.repeat(reverse: true);
    checkLoginStatus();
  }

  Future<void> checkLoginStatus() async {
    try {
      final token = await FirebaseAuth.instance.currentUser?.getIdToken();
      final userId = FirebaseAuth.instance.currentUser?.uid;
      print('userId: $userId');
      kBox.write('userId', userId);
      print('token: $token');
      kBox.write('token', token);
      if (token != null && token.isNotEmpty) {
        employeeResponse = await _authRepository.organizationMe();
        await _authRepository.getEmployeeMe();
        isOnboard = kBox.read('isOnboard') ?? false;
        await Future.delayed(const Duration(seconds: 2));
        if (FirebaseAuth.instance.currentUser != null) {
          if (token.isNotEmpty &&
              employeeResponse.success == true &&
              employeeResponse.data != null &&
              employeeResponse.data!.isNotEmpty) {
            Get.off(() => HomeNavBar());
          } else {
            Get.off(() => SignupScreen());
          }
        } else if (isOnboard) {
          Get.off(() => const LoginScreen());
        } else if (FirebaseAuth.instance.currentUser == null && isOnboard) {
          Get.off(() => const LoginScreen());
        } else {
          Get.off(() => OnboardScreen());
        }
      } else {
        Get.offAll(() => const LoginScreen());
      }
    } catch (e) {
      print(e);
      Get.off泛理(()
 Consideringblob留下Conc例子 Things sense presse control It this, 
      }
    }
  }

  @override
  void dispose() {
    animationController.dispose();
    super.dispose();
  }
}

解决方案 #

经排查，问题由Firebase Auth新版本包的bug导致，将依赖降级到以下版本后问题解决：

firebase_auth: 4.6.3
firebase_auth_platform_interface: 6.15.3
