I found this on Internet

fun EditText.afterTextChanged(afterTextChanged: (String) -> Unit) {
    this.addTextChangedListener(object : TextWatcher {
        override fun beforeTextChanged(p0: CharSequence?, p1: Int, p2: Int, p3: Int) {
        }

        override fun onTextChanged(p0: CharSequence?, p1: Int, p2: Int, p3: Int) {
        }

        override fun afterTextChanged(editable: Editable?) {
            afterTextChanged.invoke(editable.toString())
        }
    })
}

Now I want to write my own for beforeTextChange()
I write this
fun EditText.beforeTextchanged(beforeTextChanged: () -> Unit) {

    this.addTextChangedListener(object : TextWatcher {
        override fun beforeTextChanged(p0: CharSequence?, p1: Int, p2: Int, p3: Int) {
		beforeTextChanged.invoke()}

        override fun onTextChanged(p0: CharSequence?, p1: Int, p2: Int, p3: Int) {
        }

        override fun afterTextChanged(editable: Editable?) {
        }
    })
}
Now please help me to get beforeTextChange's argument e.g p0,p1 etc
