KeyboardListener is buggy after focusing a TextField #67915
Description
This is primarily an issue for physical keyboards without touch screens but it is acting weird even with touch screens. I'm trying to support chromebooks with physical keyboard, that's why this issue is blocking me. I have not yet tested enough on slates with bluetooth keyboards but this may be a big problem with those devices too.
I posted this same question in a closed issue here but I didn't get any responses so I guess it's a new bug: #11177
Steps to Reproduce
I've created a simple repro: https://github.com/mikeesouth/chromebook_keyboard
This repro is as simple as this (but my repro is slightly improved to show focus and removing unused code):
flutter create chromebook_keyboard- Add
final _keyboardListenerFocus = FocusNode();to the state class - Add
String _keyName = 'N/A';to the state class - Override dispose() and call
_keyboardListenerFocus.dispose();in the state class - Add the following to the build method (e.g. as children to the column class):
Text('Here is plain TextField:'),
Container(width: 200, child: TextField()),
SizedBox(height: 50),
Text(
'Tap the green container to show the keycode using a RawKeyboardListener:'),
GestureDetector(
onTap: () => _keyboardListenerFocus.requestFocus(),
child: Container(
width: 200,
height: 100,
color: Colors.green,
alignment: Alignment.center,
child: RawKeyboardListener(
focusNode: _keyboardListenerFocus,
onKey: (keyEvent) => setState(
() => _keyName = keyEvent.data.logicalKey.debugName),
child: Text('keyName = $_keyName'),
),
),
),
Expected results:
I expect the physical keyboard to work for the TextField and the physical keyboard to also work for the RawKeyboardListener when pressing the green container (to set focus to the keyboard listener). I expect the RawKeyboardListener to register keys (e.g. "A") when it's focused.
Actual results:
The actual result is that the RawKeyboardListener listens correctly if I focus it before focusing the TextField after application startup. But as soon as I focus the TextField and then switch back the focus to the RawKeyboardListener - then it does not register keys correctly.
If you start with the green container (keyboard listener) it recognizes all keys (i.e a, b, c, 1, 2, 3, space, left alt, left shift and so on). If you switch to the text field you can type text as expected. If you switch back to the green container - it no longer recognizes text, only modifiers such as left alt, left shift etc. BUT if you hold left alt, then it also recognizes letters and other keys (i.e. alt + a will display "_keyName = A"). Restart the app - the KeyboardListener works again but as soon as you focus the TextField the RawKeyboardListener will no longer recognize key presses.
Test device:
I'm trying this on a Chromebook without touch screen and it (of course) has a physical keyboard. The model is HP Chromebook 14-db0004no 14".
Additional information - buggy on touch screens:
Another interesting thing is that the keyboard listener correctly listens even after focusing the TextField. But an issue that may be related is that when I focus the TextField the soft keyboard shows as soon as I press a key on the physical keyboard - is this intended?
Steps to reproduce this issue that may be related:
- Start the app
- Tap the green container (to focus RawKeyboardListener)
- Press some keys (e.g. a, b, c) on my physical keyboard (Windows) - it registers correctly and no soft keyboard is displayed
- Tap the TextField (to focus it) - the soft keyboard pops up
- Type some text (e.g. "Hello World")
- Press back key on emulator to hide keyboard
- Tap the green container again (to focus RawKeyboardListener)
- Press some keys - the soft keyboard pops up again - why? (side note: on the Android Emulator this still registers the keypresses, on my Chromebook, this wouldn't recognize the keypresses if I don't hold down alt as described above)
I haven't started to test this on a hybrid device (i.e. touch screen + physical keyboard) but if the soft keyboard pops up focusing a text field when using a hybrid device with an attached keyboard, then it will become an issue for us. We would like to control when the soft keyboard shows up - it would be OK for it to show up automatically on a touch screen device without an attached keyboard.

Also experiencing this problem, tried to debug it but it seems that the keydown / up events don't fire at all when it comes to letters.
Can't find them on top of the stack frame when debugging
mikeesouth commentedon Oct 27, 2020
Is there any way to "vote" for this issue, get an estimated fix date or help out to speed up a fix? This is a real blocker for all chromebooks (at least all with a physical keyboard). Chromebook is becoming one of our primary platforms and Chromebooks are growing rapidly in popularity for our target audiences (education).
GintautasMickus commentedon Oct 27, 2020
I am also having the same problem on the Android TV platform... After focusing the text field the remote control buttons are useless....
amitozalvo commentedon Oct 27, 2020
Fot me it happens on android, ios and web.
I'm using an external bluetooth barcode scanner and it's very frustrating for my users
amitozalvo commentedon Oct 29, 2020
I am able to "fix" this behavior without restarting the app by initiating a barcode scan with the camera of the phone (using the library barcode-scan).
It's really not a workaround but this is what my users are doing right now to work with it

Hello I found a workaround to this issue which I explain on stackoverflow here: https://stackoverflow.com/questions/78245462/keyboardlistener-is-buggy-after-focusing-a-textfield/78245463
I paste the example below, for full explanation go on stackoverflow:

More than four years and this still isn't fixed 😢
While I appreciate the fix from @Lenny4 a year ago, it's far from an ideal fix. Setting readonly on a textfield stops us from selecting text, moving the cursor and other stuff (yes - this can probably be fixed with more special solutions but in practice it's a struggle that adds a lot of complexity).
I tried this example again with Flutter 3.29.1 on a brand new Android slate with Android 15 - the problem persists. The problem also persist on my old Chromebook.
This problem does not occur on iPad with physical keyboards, it seems to be an Android only problem.
@TahaTesser, @gnprice, @dam-ease do you have any tips on how I can raise the priority of this issue? Sorry for pinging you but you all added labels to the issue so I'm hoping that you have insights in how this can be prioritized.
