Flutter (Android TV) — soft keyboard overlap/hides TextFormField

Problem: I'm building a login screen for an Android TV app. The layout is a two-column panel (left: QR, right: email/password form). When the on-screen keyboard appears, the email field stays visible above the keyboard, but the password field (which is lower) is overlapped/hidden by the keyboard. How can I keep the focused field visible on Android TV?

What I expect: When a TextFormField receives focus, the UI should adjust so that the field is not hidden by the keyboard (same behavior for email and password).

What happens: The lower password field is overlapped by the keyboard on my TV layout.

Relevant code (simplified):

Widget build(BuildContext context) {
  return Scaffold(
    backgroundColor: Colors.transparent,
    body: Column(
      children: [
        _showTopBar(),
        Expanded(
          child: Center(
            child: Stack(
              children: <Widget>[
                _showForm(),
                _showCircularProgress(),
              ],
            ),
          ),
        ),
      ],
    ),
  );
}

Widget _showForm() {
  return Column(
    children: [
      Expanded(
        child: Center(
          child: Padding(
            padding: const EdgeInsets.symmetric(horizontal: 24, vertical: 8),
            child: Container(
              child: Column(
                children: [
                  // ... left column (QR) and divider ...
                  // Right: email/password column
                  Expanded(
                    child: Padding(
                      padding: const EdgeInsets.symmetric(horizontal: 24),
                      child: Center(
                        child: Form(
                          key: _formKey,
                          child: Column(
                            mainAxisSize: MainAxisSize.min,
                            children: [
                              Text("Login with Email"),
                              SizedBox(height: 20),
                              showEmailInput(),       // TextFormField with focusNode _emailFocus
                              SizedBox(height: 16),
                              showPasswordInput(),    // TextFormField with focusNode _passwordFocus
                              SizedBox(height: 24),
                              showPrimaryButton(),
                            ],
                          ),
                        ),
                      ),
                    ),
                  ),
                ],
              ),
            ),
          ),
        ),
      ),
    ],
  );
}

Widget showEmailInput() => TextFormField(
  keyboardType: TextInputType.emailAddress,
  focusNode: _emailFocus,
  onFieldSubmitted: (_) {
    _emailFocus.unfocus();
    FocusScope.of(context).requestFocus(_passwordFocus);
  },
  ...
);

Widget showPasswordInput() => TextFormField(
  obscureText: true,
  focusNode: _passwordFocus,
  ...
);

Environment

• Flutter on Android TV

What I've tried but didnt worked

• Adding resizeToAvoidBottomInset to true/false (vise-versa) inside Widget Build Scaffold
• Adding SingleChildScrollView and set physics property to BouncingScrollPhysics
