    binding = ActivitySignupBinding.inflate(layoutInflater)
    super.onCreate(savedInstanceState)
    setContentView(binding.root)

    supportActionBar?.hide()

    mAuth = FirebaseAuth.getInstance()



    binding.signupbutton.setOnClickListener {

        val email = binding.signupmail.text.toString().trim()
        val password = binding.signuppassword.text.toString().trim()
        val name = binding.signupname.text.toString().trim()

        if (email.isEmpty()){

            binding.signupmail.error = "Email is Empty"
            binding.signupmail.requestFocus()
            return@setOnClickListener
        }

        when {
            name.isEmpty() -> {

                binding.signupname.error = "Name is Empty"
                binding.signupname.requestFocus()
                return@setOnClickListener
            }
            password.isEmpty() -> {

                binding.signuppassword.error= "Enter password"
                binding.signuppassword.requestFocus()
                return@setOnClickListener
            }
            else -> {


                mAuth.createUserWithEmailAndPassword(email,password)

                    .addOnCompleteListener(this){task->

                        if (task.isSuccessful) {

                            saveUserInfo(name,email,mAuth.currentUser?.uid!!)

                        } else Toast.makeText(this , "Some Error occurred", Toast.LENGTH_LONG).show()


                    }
            }
        }

    }
    }

private fun saveUserInfo(name: String, email: String,  uid: String) {
    mDbRef =FirebaseDatabase.getInstance().getReference()

    mDbRef.child("user").child(uid).setValue(User(name,email, uid))        
}

}
