I have a widget that has an image element and an expanded list of form elements, which when filling and scrolling data disappears when it scrolls for the image. It does not throw any errors during debugging, and this happens in any field that scrolls behind the image at the top of the widget. Any ideas?
@override
Widget build(BuildContext context) {
var _children = <Widget>[
new Center(
child: new Text(widget.prov.fname + widget.prov.lname,
style: new TextStyle(fontSize: 20.0, fontWeight: FontWeight.bold),
),
),
new Center(
child: new Container(
padding: new EdgeInsets.only(
left: 125.0, right: 125.0, bottom: 50.0),
child: new Image.network('http://174.138.61.246:8080/getimage/'+widget.prov.pic.assetName),
)
),
new Form(
key: _formKey,
autovalidate: _autovalidate,
onWillPop: _warnUserAboutInvalidData,
child: new Expanded(
child: new ListView(
padding: const EdgeInsets.symmetric(horizontal: 16.0),
children: <Widget>[
new TextFormField(
decoration: const InputDecoration(
icon: const Icon(Icons.person),
hintText: 'First Name?',
labelText: 'First Name *',
),
onSaved: (String value) { referral.fname = value; },

validator: _validatePhoneNumber,
// TextInputFormatters are applied in sequence.
inputFormatters: <TextInputFormatter> [
WhitelistingTextInputFormatter.digitsOnly,
// Fit the validating format.
_phoneNumberFormatter,
],
),
new TextFormField(
decoration: const InputDecoration(
hintText: 'Tell us about patient',
helperText: 'It does not have to be detailed yet',
labelText: 'Referral Details',

maxLines: 5,

new _DateTimePicker(

selectDate: (DateTime date) {
setState(() {
referral.dob = date;

new InputDecorator(

setState(() {
_typeAppt = newValue;
});
},
items: _allTypeAppt.map((String value) {
return new DropdownMenuItem<String>(
value: value,
child: new Text(value),
);
}).toList(),
),
),
],
)
)
),
/*new RefreshIndicator(
child: new ListView.builder(
itemBuilder: _itemBuilder,
itemCount: listcount,
),
onRefresh: _onRefresh,
),*/
];
return new Scaffold(
appBar: new AppBar(title: new Text("My Provider")),
body: new Column(
children: _children,
),
);
}
