Copy code
LaunchedEffect(textFieldText) {
// do afterTextChanged
}textFieldTextThere are other ways depending on your use case, but I'd need more info on what you're doing.

02/27/2021, 6:57 PMThanks Dominic - this is good - But LaunchedEffect() gets called for every character I type - So within this LaunchedEffect(text!!) - I need to do an operation after entire text has been entered. so want an equivalent of afterTextChanged() so only after entire text is entered I can get a handle

02/27/2021, 6:59 PMHow do you know when the text has stopped changing though? You don't really know when the user is done typing.

02/27/2021, 6:59 PMand do my operation only once instead of multiple times as every character gets entered in the Textfield
hmmm.
In conventional case
Copy code
tField!!.addTextChangedListener(object : TextWatcher {
override fun beforeTextChanged(charSequence: CharSequence, i: Int, i1: Int, i2: Int) {}
override fun onTextChanged(charSequence: CharSequence, i: Int, i1: Int, i2: Int) {
}
override fun afterTextChanged(editable: Editable) {}
})d

(Sorry, haven't done Android in a long time)

02/27/2021, 7:02 PMI understand that we don’t know when the user has stopped typing - I am trying to see if performance can be improved here instead of doing of going thru mutiple times. I will explore focus modifier .
Thanks - Launchedeffect was very helpful
