Flutter 颤振：我已经使用firebase auth与提供者。它在调试时工作正常，但在发布时应用程序崩溃

我试图创建发布apk，但当发布apk并运行我的发布设备时，它会崩溃，但在调试中，您可以找到它。我已在firebase验证代码中检查并发布。谁能帮帮我吗

main.dart代码

class MyApp extends StatelessWidget {
  bool isFirstTime;
  ThemeData appTheme;

  MyApp(bool isFirstTime,ThemeData appTheme) {
    this.isFirstTime = isFirstTime;
    this.appTheme=appTheme;
  }
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {

    return MultiProvider(
      providers: [
        StreamProvider<UserModel>.value(
          value: Auth().onAuthStateChanged,
        ),
        Provider<Database>(create: (_)=>RealtimeDatabase(),),

        Provider<AuthBase>(create: (_)=>Auth(),),
        ChangeNotifierProvider.value(value: UserAddressesViewModel()),
        ChangeNotifierProvider.value(value: GoogleMapsFindAddressModel()),
        ChangeNotifierProvider.value(value: SelectAddressViewModel()),
        ChangeNotifierProvider.value(value: AppThemeViewModel(appTheme))

      ],
      child: CMaterialAppWidget(isFirstTime: isFirstTime,),
    );
  }
}

您是否已将sha密钥添加到Firebase控制台

注意：调试和发布的sha密钥不同

---

您可以使用./android/gradlew signingReport找到您的密钥

如果您已将sha添加到firebase中，请尝试在build.gradle上删除signingConfig signingConfigs.debug
