Can't focus Textfield after switching tabs with BottomNavigationBar

[Syphonjr]

Hi, I have an application with 3 tabs where I use AutomaticKeepAliveClientMixin to keep my navigation state in my tabs. In my tabs I have textfields but after switching tabs, I can only edit the textfield in the second tab,I can't focus and edit anymore on the remaining ones. I can still however copy and paste and press on buttons.

I created a new application and the problem still persist.

Code

My bottom navigation in my main view

  @override
  Widget build(BuildContext context) {
    return new Scaffold(
      body: PageView(
        children: [new HomeTab(), new PresentationsTab(), new ThirdTab()],
        controller: _pageController,
        onPageChanged: pageChanged,
      ),
      bottomNavigationBar: new BottomNavigationBar(
        currentIndex: _page,
        onTap: tapBottomNav,
        items: [
          new BottomNavigationBarItem(
            icon: new Icon(Icons.home),
            title: new Text('Home'),
          ),
          new BottomNavigationBarItem(
            icon: new Icon(Icons.pregnant_woman),
            title: new Text('Presentation'),
          ),
          new BottomNavigationBarItem(
            icon: new Icon(Icons.pregnant_woman),
            title: new Text('Presentation'),
          )
        ],
      ),
    );
  

My HomeTab() (other widgets look the same)

import 'package:flutter/material.dart';
import 'choosepage.dart';

class HomeTab extends StatefulWidget {
  @override
  HomeTabState createState() {
    return new HomeTabState();
  }
}

class HomeTabState extends State<HomeTab>
    with AutomaticKeepAliveClientMixin<HomeTab> {
  @override
  bool get wantKeepAlive => true;

  @override
  Widget build(BuildContext context) {
    return new Navigator(
      initialRoute: 'home/chooseroom',
      onGenerateRoute: (RouteSettings settings) {
        WidgetBuilder builder;
        switch (settings.name) {
          case 'home/chooseroom':
            // Assume CollectPersonalInfoPage collects personal info and then
            // navigates to 'signup/choose_credentials'.
            builder = (BuildContext _) => new ChoosePage();
            break;
          default:
            throw new Exception('Invalid route: ${settings.name}');
        }
        return new MaterialPageRoute(builder: builder, settings: settings);
      },
    );
  }
}

And choose page just builds a textfield

Steps to Reproduce

1. Start the application
2. Switch tabs
3. Can't focus on textinput
