I tried to add Filtered Categories page on myapplication there is no error in my code but when i try to run my app im gettin that error and i need help asap

>Solution :

You need to instanciate your binding before using it.

override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        // Instanciating the binding first
        binding = ActivityTariflerPageUserBinding.inflate(layoutInflater)
        // Use it on the content view
        setContentView(binding.root)
        firebaseAuth = FirebaseAuth.getInstance()

        setupWithViewPagerAdapter(binding.viewPager)
        binding.tabLayout.setupWithViewPager(binding.viewPager)

        binding.backBtn.setOnClickListener{
            startActivity(Intent(this,ManiAnasayfa::class.java))
        }
        binding.fabBtn.setOnClickListener{
            startActivity(Intent(this,TarifEkleAdmin::class.java))
        }
    }
