TextFormField cursor did not move when changes occur - flutter

Question

I have a screen that shows a textformfield, I want to retrieve the value that the user has inputted. But when I made a change the cursor didn't move, so it stays at position 0. How do I solve this problem?
class ScreenFormArtikel extends StatefulWidget {
final String mode;
ScreenFormArtikel(this.mode);
#override
_ScreenFormArtikelState createState() => _ScreenFormArtikelState();
}
class _ScreenFormArtikelState extends State<ScreenFormArtikel> {
var _key = GlobalKey<FormState>();
var _titleController = TextEditingController();
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('Article'),
),
body: Container(
child: Form(
key: _key,
child: Column(
children: [
Consumer<ProviderArtikel>(
builder: (context, artikel, child) {
return TextFormField(
decoration: InputDecoration(
labelText: 'Title',
floatingLabelBehavior: FloatingLabelBehavior.always),
controller: _titleController,
validator: (value) {
if (value.isEmpty) {
return "Please fill this field";
}
return null;
},
onChanged: (value) {
_titleController.text = value;
},
);
},
),
RaisedButton(onPressed: () {}),
],
),
),
),
);
}
}

Commenting the onChanged will do the work.
TextFormField(
decoration: InputDecoration(
labelText: 'Title',
floatingLabelBehavior: FloatingLabelBehavior.always),
controller: _titleController,
validator: (value) {
if (value.isEmpty) {
return "Please fill this field";
}
return null;
},
// onChanged: (value) {
// _titleController.text = value;
// },
),
Actually the _titleController.text is setting the text onChange, that's why cursor is moving to the first place.
And you don't have to explicitly do the onTextChange thing.
