Does anyone know what could be the issue ?
Android Solutions
Solution 1 - Android
I would suggest replacing the top Column widget with a ListView, that automatically resizes on keyboard input, whilst also supporting scrolling.
If you really want this setup as it is, you can edit your Scaffold with the parameter
resizeToAvoidBottomPadding: false
That should make the error disappear
Solution 2 - Android
Scaffold(
resizeToAvoidBottomInset: false, // set it to false
...
)
As Andrey said, you may have issues with scrolling, so you may try
Scaffold(
resizeToAvoidBottomInset: false, // set it to false
body: SingleChildScrollView(child: YourBody()),
)
Solution 3 - Android
you usually need to provide a scroll widget on top of your widgets because if you try to open the keyboard or change the orientation of your phone, flutter needs to know how to handle the distribution of the widgets on the screen.
Please review this resource, you can check the different options that flutter provide Out of the box, and choose the best option for your scenario.
Solution 4 - Android
With resizeToAvoidBottomPadding: false
in Scaffold, You don't see all the widgets that are below the open textfield. The solution is to insert a container with a SingleChildScrollView inside. Example:
Container(
alignment: Alignment.center,
width: double.infinity,
height: double.infinity,
color: viewModel.color,
child: SingleChildScrollView(child:"Your widgets"));
Solution 5 - Android
wrap your child view into ListView will solve the prob. Please check this
class _LoginScreenState extends State<LoginScreen> {
@override
Widget build(BuildContext context) {
return new Scaffold(
body: new Container(
child: ListView(
children: <Widget>[
Padding(
padding: const EdgeInsets.all(8.0),
child: new Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
new Padding(
padding: EdgeInsets.only(left: 1,top: 50,right: 1,bottom: 1),
child: new Text("jk", style: TextStyle(fontFamily: "mono_bold")),
),
new Padding(
padding: EdgeInsets.only(left: 1,top: 50,right: 1,bottom: 1),
child: new TextField(
style: new TextStyle(),
decoration: InputDecoration(
labelText: "Email",
contentPadding: EdgeInsets.all(8.0)
),
keyboardType: TextInputType.emailAddress,
)
),
new Padding(
padding: EdgeInsets.only(left: 1,top: 50,right: 1,bottom: 1),
child: new TextField(
style: new TextStyle(
),
decoration: InputDecoration(
labelText: "Password"
),
keyboardType: TextInputType.text,
obscureText: true,
),
),
],
),
),
],
)
),
);
}
Solution 6 - Android
wrap your column into SingleChildScrollView
will solve the problem. Please check this:
Widget build(BuildContext context) {
return Scaffold(
body: Container(
child: Center(
child: SingleChildScrollView(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
TextField(),
TextField(),
],
),
))));
}
And You also use for removing yellow black overflow line
resizeToAvoidBottomPadding: false
but in this case, TextField
does not move up on click time.
Solution 7 - Android
wrap with SingleChildScrollView Widget here's my code to solve this situation: it is best and easiest method
SingleChildScrollView(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.stretch,
children: <Widget>[
Hero(
tag: 'logo',
child: Container(
height: 200.0,
child: Image.asset('images/logo.png'),
),
),
SizedBox(
height: 48.0,
),
TextField(
onChanged: (value) {
//Do something with the user input.
},
decoration: kTextFieldDecoration.copyWith(hintText: 'Enter username'),
),
SizedBox(
height: 8.0,
),
TextField(
onChanged: (value) {
//Do something with the user input.
},
decoration: kTextFieldDecoration.copyWith(hintText: 'Enter password'),
),
SizedBox(
height: 24.0,
),
RoundedButton(
colour: Colors.blueAccent,
text: 'Register',
onPressed: () {
//later todo
},
),
],
),
),
Solution 8 - Android
You can set resizeToAvoidBottomInset: false
for avoiding overflow, but you can't reach fields in bottom of page, which can be covered by keyboard.
Or you can wrap body of Scaffold
inside SingleChildScrollView
Solution 9 - Android
You can enclose all the widgets within the ListView.
So you can scroll it and the overloaded will disappear.
Solution 10 - Android
Put your content in to SingleChildScrollView and add a ConstrainedBox and try
https://api.flutter.dev/flutter/widgets/SingleChildScrollView-class.html
Solution 11 - Android
Wrap your top column inside SingleChildScrollView
.
Make you layout scrollable.
Solution 12 - Android
You can wrap your Fields in single child ScrollView
of Flutter.
Solution 13 - Android
This align items bottom to top, Try this..
child: SizedBox(
height: MediaQuery.of(context).size.height,
child: SingleChildScrollView(
reverse: true,
Solution 14 - Android
Remove unwanted padding top and bottom
child: Container(
height: size.height,
width: size.width,
padding: EdgeInsets.only(
left: size.width * 0.15,
right: size.width * 0.15,
top: size.width * 0.15,
bottom: size.width * 0.15,
),
to change by this
child: Container(
height: size.height,
width: size.width,
padding: EdgeInsets.only(
left: size.width * 0.15,
right: size.width * 0.15,
),
This worked for me.
Solution 15 - Android
you should add resizeToAvoidBottomInset: false, and put your button in child:SingleChildScrollView() like the following code below :
Widget build(BuildContext context) {
return Scaffold(
resizeToAvoidBottomInset: false,
appBar: PreferredSize(
preferredSize:const Size(double.infinity,100),
child:(ResponsiveLayout.isTinyLimit(context) ||
ResponsiveLayout.isTinyHeightLimit(context))
? Container()
: const AppBarWidget(),
),
body: Center(
child:SingleChildScrollView(
child: Padding(
padding: const EdgeInsets.all(8.0),
child: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center ,
children: [
Text("Temperature"),
LineChartSample2(),
Text("Gas Level"),
LineChartSample2(),
on?Icon(Icons.lightbulb,
size:100,
color: Colors.lightBlue.shade700 ,
):const Icon(Icons.lightbulb_outline,
size:100,
),
ElevatedButton(
style: TextButton.styleFrom(
backgroundColor: on? Colors.green: Colors.white10),
onPressed: (){
dbR.child("movement").set({"Switch":!on});
setState(() {
on = !on;
});
},
child:on ? const Text("On"):const Text("Off"))
],
),
),
) ),
),
);
Solution 16 - Android
Try wrapping your main Column with
1.(ListView and give property shrinkWrap: true,) List view has property children:
2.( SingleChildScrollView() )but it has only child: , .
Something like:
child: ListView(shrinkWrap: true, children: <Widget>[
new Column(children: <Widget>[
Container(
padding: EdgeInsets.all(120.0),
child: Center(
child: Icon(
Icons.headset_mic,

size: 50.0,
),
),
),
new Row(
children: <Widget>[
new Expanded(
child: new Padding(
padding: const EdgeInsets.only(left: 40.0),
child: new Text(
"EMAIL",
style: TextStyle(
fontWeight: FontWeight.bold,
color: Colors.redAccent,
fontSize: 15.0,
),
),
),
),
],
),
new Container(
width: MediaQuery.of(context).size.width,
margin: const EdgeInsets.only(
left: 40.0, right: 40.0, top: 10.0),
alignment: Alignment.center,

],
),
new Container(

margin: const EdgeInsets.only(
left: 40.0, right: 40.0, top: 10.0),
