I got some issue with my code and I can't find anything to help me. I'm trying to clear my edittext when I'm typing any char. I got this error

/AndroidRuntime: FATAL EXCEPTION: main

And my code is like that

binding.formInputQuantity.editTextValue.addTextChangedListener(object: TextWatcher{
            override fun onTextChanged(s: CharSequence?, start: Int, before: Int, count: Int) {

            }
            override fun beforeTextChanged(p0: CharSequence?, p1: Int, p2: Int, p3: Int) {
                if(locationIsFocused){
                    locationIsFocused = false
                    binding.formInputQuantity.editTextValue.text.clear()
                }
            }

            override fun afterTextChanged(p0: Editable?) {

            }
        })

locationEditText.onFocusChangeListener = View.OnFocusChangeListener { v, hasFocus ->
            locationIsFocused = true
        }

When I launch the step by step, everything is working fine, but not when I run it normally.

Thanks !
