Flutter redirects on textFormField open - flutter

Question

whenever i click on the textFormField the keyboard opens and closes almost immediately i think it kinda refreshes the page. i have another page with a form where i dont face this problem.
here is the code for that page, the other form i have in the app is almost identical to this one
import 'package:flutter/material.dart';
import 'package:scoped_model/scoped_model.dart';
import '../scoped_models/products.dart';
class ProductAdd extends StatelessWidget {
final _formData = {
'title': null,
'description': null,
'price': null,
'image': 'assets/food.jpg'
};
final GlobalKey<FormState> _formKey = GlobalKey<FormState>();
Widget _titleField() {
return TextFormField(
decoration: InputDecoration(labelText: 'Enter Title'),
keyboardType: TextInputType.text,
validator: (String value) {
if (value.isEmpty) {
return 'Please enter a valid title';
}
},
onSaved: (value) {
print(value);
_formData['title'] = value;
},
);
}
Widget _descriptionField() {
return TextFormField(
decoration: InputDecoration(labelText: 'Enter Description'),
keyboardType: TextInputType.text,
validator: (String value) {
if (value.isEmpty) {
return 'Please enter a valid description';
}
},
onSaved: (value) {
print(value);
_formData['description'] = value;
},
);
}
Widget _priceField() {
return TextFormField(
decoration: InputDecoration(labelText: 'Enter Price'),
keyboardType: TextInputType.number,
validator: (String value) {
if (value.isEmpty) {
return 'Please enter a valid price';
}
},
onSaved: (value) {
print(value);
_formData['price'] = value;
},
);
}
Widget _submitButton(context) {
return RaisedButton(
textColor: Colors.white,
child: Text('LOGIN'),
onPressed: () {
if (!_formKey.currentState.validate()) {
return;
}
_formKey.currentState.save();
Navigator.pushReplacementNamed(context, '/products');
},
);
}
#override
Widget build(BuildContext context) {
return ScopedModelDescendant<ProductsModel>(
builder: (context, child, ProductsModel model) {
return Container(
child: Center(
child: Container(
child: SingleChildScrollView(
child: Container(
padding: EdgeInsets.all(20.0),
child: Form(
key: _formKey,
child: Column(
children: <Widget>[
_titleField(),
_descriptionField(),
_priceField(),
SizedBox(
height: 10.0,
),
_submitButton(context)
],
),
),
),
),
),
),
);
},
);
}
}
i'm using flutter version: 1.0.0

I was not able to reproduce the issue. I re-created your case and the keyboard worked just fine. I although skipped the scoped-model part of your code because I don't know how your setup is. But with minimal code, I couldn't replicate it. See below:
import 'package:flutter/material.dart';
import 'package:scoped_model/scoped_model.dart';
//import '../scoped_models/products.dart';
void main() => runApp(new MyApp());
class MyApp extends StatelessWidget {
#override
Widget build(BuildContext context) {
return MaterialApp(
home: ProductAdd(),
);
}
}
class ProductAdd extends StatelessWidget {
final _formData = {
'title': null,
'description': null,
'price': null,
'image': 'assets/food.jpg'
};
final GlobalKey<FormState> _formKey = GlobalKey<FormState>();
Widget _titleField() {
return TextFormField(
decoration: InputDecoration(labelText: 'Enter Title'),
keyboardType: TextInputType.text,
validator: (String value) {
if (value.isEmpty) {
return 'Please enter a valid title';
}
},
onSaved: (value) {
print(value);
_formData['title'] = value;
},
);
}
Widget _descriptionField() {
return TextFormField(
decoration: InputDecoration(labelText: 'Enter Description'),
keyboardType: TextInputType.text,
validator: (String value) {
if (value.isEmpty) {
return 'Please enter a valid description';
}
},
onSaved: (value) {
print(value);
_formData['description'] = value;
},
);
}
Widget _priceField() {
return TextFormField(
decoration: InputDecoration(labelText: 'Enter Price'),
keyboardType: TextInputType.number,
validator: (String value) {
if (value.isEmpty) {
return 'Please enter a valid price';
}
},
onSaved: (value) {
print(value);
_formData['price'] = value;
},
);
}
Widget _submitButton(context) {
return RaisedButton(
textColor: Colors.white,
child: Text('LOGIN'),
onPressed: () {
if (!_formKey.currentState.validate()) {
return;
}
_formKey.currentState.save();
Navigator.pushReplacementNamed(context, '/products');
},
);
}
#override
Widget build(BuildContext context) {
return Scaffold(
body: Center(
child: Container(
child: SingleChildScrollView(
child: Container(
padding: EdgeInsets.all(20.0),
child: Form(
key: _formKey,
child: Column(
children: <Widget>[
_titleField(),
_descriptionField(),
_priceField(),
SizedBox(
height: 10.0,
),
_submitButton(context)
],
),
),
),
),
),
),
);
}
}
My Flutter version: 0.11.10

Answer 2

this is my correction, hope it works; u need to add TextEditingController titlecontroller froeach TextFormField,dont use onsaved() ; and on the submitbutton funtion use this :
TextEditingController _pricecontroller;
Widget _priceField() {
return TextFormField(
//addcontroller;
controller : __pricecontroller
decoration: InputDecoration(labelText: 'Enter Price'),
keyboardType: TextInputType.number,
validator: (String value) {
if (value.isEmpty) {
return 'Please enter a valid price';
}
},
onSaved: (value) {
print(value);
_formData['price'] = value;
},
);
}
Widget _submitButton(context) {
return RaisedButton(
textColor: Colors.white,
child: Text('LOGIN'),
onPressed: () {
if (!_formKey.currentState.validate()) {
_formKey.currentState.save();
_formData['title'] = __titlecontroller.text;
_formData['description'] = __desccontroller.text;
_formData['price'] = __pricecontroller.text;
}
Navigator.pushReplacementNamed(context, '/products');
},
);
}
