I am not sure that if this will help you but I was also facing the same issue. I was getting this error when I was using the TextFormField with in Form and the issue was that I created the global form key with in the build method.

class _AddTaskState extends State<AddTask> {
final _formKey = GlobalKey<FormState>(); // <-
String name;
String description;
@override
Widget build(BuildContext context) {
 // first I was using that here.
return Scaffold(

In my case I had TextFeild in AnimatedSwitcher. The problem was i had key: UniqueKey() inside my widget that containes the TextFeild. So When ever i touched the text feid UniqueKey() gets called and then the widget tree gets regernated.

Answer 3

If you are using form validator, move your form key out of your build context. This should solve your issue.

Instead of -

class SingInScreen extends StatelessWidget {
final _sigInFormKey = GlobalKey<FormState>();
  @override
  Widget build(BuildContext context) {
    Size size = getRelativeSize(context);

Use this-

`final _sigInFormKey = GlobalKey<FormState>();

class SingInScreen extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    Size size = getRelativeSize(context);`

Known issue, tracked here,it's still there. There is no explanation on what's causing it.

I did a little bit of digging. It looks like Android is generating these warnings because we are holding the InputConnection incorrectly in the Engine's TextInputPlugin. I haven't really figured out what we're doing wrong, though.
