Some Android keyevents are not working with Flutter app

Stack:

Android 12.0 (emulator)
Maven 3.9.1
Java 11
MacOS 13.0
Appium 2.0.0-beta.52
Java Client 8.3.0
Selenium Java 4.8.0
TestNG 7.7.0

Description:

Since we have no displayed keyboard in the app with flutter_driver enabled, I found that it's a problem to "simulate" pressing on Enter button, there is no reaction on any of my action to the emulator/app. BUT, there is no problem with Delete button. After some additional investigation I found that Enter, A-Z, 0-9 are not working at all, but Delete, Escape, Tab are working properly (I didn't check all keyevents that Android have, but here the list of them). I tried different ways to interact with Enter button:

Map<String, Object> cmd = ImmutableMap.of("command", "input", "args", List.of("keyevent", 66));
((AndroidDriver)driver).executeScript("mobile: shell", cmd);

or

((AndroidDriver) driver).pressKey(new KeyEvent(AndroidKey.ENTER));

or directly in terminal

adb shell input keyevent 66

All these methods perform exact the same action, as far as I understood, but with no result in case of Enter, A-Z, 0-9 buttons. If I try to replace Enter button with Delete - everything works great.

I also tried to use Selenium sequence:

final KeyInput keyboard = new KeyInput("keyboard");
Sequence sequence = new Sequence(keyboard,  0);
sequence.addAction(keyboard.createKeyDown(Keys.ENTER.getCodePoint()));
sequence.addAction(keyboard.createKeyUp(Keys.ENTER.getCodePoint()));
driver.perform(Collections.singleton(sequence));

As a result, I have the same behaviour, Enter isn't working, but Delete is working properly (Backspace is working too). I even tried to use a sendKeys (or flutter:enterText) methods:

searchField.sendKeys("\n");
searchField.sendKeys("\uE006"); RETURN keyCode
searchField.sendKeys("\uE007"); ENTER keyCode

or 

((AndroidDriver) driver).context("FLUTTER");
driver.executeScript("flutter:enterText", "\n");
driver.executeScript("flutter:enterText", "\uE006");
driver.executeScript("flutter:enterText", "\uE007");
((AndroidDriver) driver).context("NATIVE_APP");

No results from these actions as well. All actions were performed with EditText element in NATIVE_APP context (except last Flutter action)

Question: Is it possible to simulate tapping/clicking on Enter, A-Z, 0-9 buttons with flutter_driver enabled?
