This happens every time I have a dirty form on one tab, move to another tab with the same form and come back.

@MSchrenker commented a test case below to reproduce a similar issue.

Could you provide a small test case that demonstrates this problem?

I got the same error. I reduced my much larger code to the one below. It looks like it happens only, when the tabController has an listener, which calls setState. As soon as setState is not called anymore everything is fine. Is it a bad idea to call setState in the listener? I used it to dynamically apply a page title to the new widget in front.

Reproduction of the issue

  1. start app and
  2. swipe left often, then it should happen.
import 'package:flutter/material.dart';

void main() => runApp(new MyApp());

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return new MaterialApp(
      title: 'Flutter issue 18063',
      theme: new ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: new TabbedPage(title: 'Flutter issue 18063'),
    );
  }
}

class TabbedPage extends StatefulWidget {
  TabbedPage({Key key, this.title}) : super(key: key);

  final String title;

  @override
  _TabbedPageState createState() => new _TabbedPageState();
}

class _TabbedPageState extends State<TabbedPage>
    with SingleTickerProviderStateMixin {
  List<Widget> pages;
  TabController _tabController;

  @override
  void initState() {
    super.initState();

    pages = [
      new FormScreen(),
      new FormScreen(),
      new FormScreen(),
      new FormScreen(),
      new FormScreen(),
      new FormScreen(),
      new FormScreen(),
    ];

    _tabController = new TabController(length: pages.length, vsync: this);
    _tabController.addListener(_handleTabSelection);
  }

  void _handleTabSelection() {
    setState(() {});
  }

  @override
  void dispose() {
    _tabController.dispose();
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {

    return new Scaffold(
      appBar: new AppBar(
        title: new Text(widget.title),
      ),
      resizeToAvoidBottomPadding: true,
      body: new Column(
        mainAxisAlignment: MainAxisAlignment.center,
        children: <Widget>[
          new Expanded(
              child: new TabBarView(
            children: pages.map((Widget widget) {
              return new Container(
                child: widget,
              );
            }).toList(),
            controller: _tabController,
          ))
        ],
      ),
    );
  }
}

class FormScreen extends StatefulWidget {
  @override
  State<StatefulWidget> createState() {
    return new _FormScreenState();
  }
}

class _FormScreenState extends State<FormScreen> {

  @override
  Widget build(BuildContext context) {
    return new Container(
      child: new Padding(
        padding: new EdgeInsets.all(8.0),
        child: new Form(
          autovalidate: false,
          child: new ListView(
            children: <Widget>[
              new TextFormField(
                decoration: new InputDecoration(
                  labelText: "Customer ",
                  hintText: "Hint Costumer",
                ),
              ),
              new TextFormField(
                decoration: new InputDecoration(
                    labelText: "Friend", hintText: 'Label Friend'),
              ),
            ],
          ),
        ),
      ),
    );
  }
}

@MSchrenker I think your correct because I have a listener on my form that calls setState().

@qwezey I am not sure anymore. On my slower laptop and with an android emulator, I get the error, when there is a listener defined. There I don't need to call setState. But on the two physical devices I tried, it works fine as long setState is not called in the listener. I guess it has something to do with the tabController and its management/caching of its pages.

@MSchrenker that confirms the issue arises when you call setState() in the listener. In my case, I need to call setState() because I want that as the user types the submit button be disabled when the form is not validated and enabled when the form is validated.

@MSchrenker I just realized you don't have a listener on your Form, but I do on the onChanged property that calls setState() to get my desired result.
