Autofocus not working on iOS

[denddyprod]

Steps that I made:

Click button to the second page
My keyboard doesnt appear but focuses on input.
Click on the button that leads to the back page.
Press again the button leading to the second page

Expected results:

My expectation is that every time I enter the page my keyboard and focus will appear on the input.

Actual results:

After a few repetitions of the steps mentioned above, the focus remains on the input but the keyboard no longer appears.

This only happens on Safari on iOS, I also tested it on Chrome ( on iOS ) and Android phones as a result it worked. A strange fact is that the keyboard does not appear even though the focus is visible on the given input.

Code sample:

import 'package:flutter/material.dart';
import 'package:flutter/services.dart';
import 'package:keyboard_actions/keyboard_actions.dart';
import 'package:keyboard_actions/keyboard_actions_item.dart';

void main() {
  runApp(const MaterialApp(
    title: 'Navigation Basics',
    home: FirstRoute(),
  ));
}

class FirstRoute extends StatelessWidget {
  const FirstRoute({super.key});

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text('First Route'),
      ),
      body: Center(
        child: ElevatedButton(
          child: const Text('Open route'),
          onPressed: () {
            Navigator.push(
              context,
              MaterialPageRoute(builder: (context) => SecondRoute()),
            );
          },
        ),
      ),
    );
  }
}

class SecondRoute extends StatefulWidget {
  SecondRoute({super.key});

  @override
  State<SecondRoute> createState() => _SecondRouteState();
}

class _SecondRouteState extends State<SecondRoute> {
  late FocusNode _nodeText1;
  late TextEditingController _controller1;

  KeyboardActionsConfig _buildConfig(BuildContext context) {
    return KeyboardActionsConfig(
      keyboardActionsPlatform: KeyboardActionsPlatform.ALL,
      keyboardBarColor: Colors.grey[200],
      nextFocus: false,
      actions: [
        KeyboardActionsItem(
          focusNode: _nodeText1,
        ),
      ],
    );
  }

  void initState() {
    super.initState();
    _nodeText1 = FocusNode();
    _controller1 = TextEditingController();
  }

  @override
  void dispose() {
    _nodeText1.dispose();
    _controller1.dispose();
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text('Second Route'),
      ),
      body: KeyboardActions(
        config: _buildConfig(context),
        child: Container(
            width: double.infinity,
            child: Column(
              mainAxisAlignment: MainAxisAlignment.center,
              crossAxisAlignment: CrossAxisAlignment.center,
              children: [
                TextField(
                  autofocus: true,
                  keyboardType: TextInputType.number,
                  focusNode: _nodeText1,
                  controller: _controller1,
                  decoration: InputDecoration(
                    hintText: "Input Number",
                  ),
                ),
                ElevatedButton(
                  onPressed: () {
                    Navigator.pop(context);
                  },
                  child: const Text('Go back!'),
                )
              ],
            )),
      ),
    );
  }
}

Did you try using KeyboardActions above Column and not Container ?
