  @override
  Widget build(BuildContext context) {
    return BlocProvider(
      create: (context) => SignInCubit(),
      child: BlocConsumer<SignInCubit, SignInStates>(
        listener: (context, state) {
          var cubit = SignInCubit.getCubit(context);

          if(state is SignInSuccessState){
            Navigator.of(context).pushNamed(HomeScreen.routeName);
          }

          if(state is SignInFailureState){
