Issue: [Android] [Stable]: textfield only shows first char typed using physical keyboard and doesn't show rest of the text.
Labels: a: text input,platform-android,has reproducible steps,found in release: 3.19,team-text-input

### Steps to reproduce

This problem occurs with the Samsung keyboard, which is the default keyboard for Samsung mobile phones.
I tested it on Samsung Galaxy S20.
The reason I tested on the master branch was to see if [this issue](https://github.com/flutter/engine/pull/49829) resolved the existing problems with Samsung keyboards.

1. Run the attached sample code.
2. Tap the text field.
3. Try entering one letter using the hardware keyboard.
4. Try entering another letter using the hardware keyboard.

### Expected results

When the TextField gets focus, the software keyboard should appear, and then when you type a letter on the hardware keyboard, the software keyboard should disappear. Afterwards, the software keyboard should not appear when entering additional characters.

In native apps such as Google Play, the software keyboard appears only when the TextField is focused, and after that, when you enter the first character with the hardware keyboard, the software keyboard disappears and does not appear again.

### Actual results

Every time I type a letter on the hardware keyboard, the software keyboard quickly disappears and reappears. After that, the software keyboard disappears and reappears every time you enter the next character.

    );
