hi guys, do you know how can i detect when the back button has been pressed? i tried with all the KeyboardActions but none of them are triggered when i press that button 😕 (using BasicTextField)

That’s the delete button. https://developer.android.com/reference/android/view/KeyEvent#KEYCODE_DEL

i tried with this and didnt work

.onKeyEvent {
                    if (it.nativeKeyEvent.keyCode == KEYCODE_DEL) {
                        onBack()
                    }
                    true
                }

Add a log to the top of that block and record the key code in the log. When you press the key you want, you’ll get the code back and you can register for that key press.

I recommend against setting that delete key as the back button, for whatever it’s worth

it doesn’t trigger the block, it does to alll other keys but no to KEYCODE_DEL 😞

keyboardOptions = KeyboardOptions(keyboardType = KeyboardType.Number),
            modifier = Modifier
                .align(Alignment.Center)
                .onKeyEvent {
                    Log.e("key", "${it.nativeKeyEvent.keyCode}")
                    if (it.nativeKeyEvent.keyCode == KEYCODE_DEL) {
                        onBack()
                    }
                    true
                }
                .focusRequester(focusRequester)

Well, the other route is to use imeOptions to make the actual back button available on the keyboard: https://developer.android.com/reference/android/widget/TextView#attr_android:imeOptions
