I am trying to create a chat screen with text field at the bottom and whenever it is clicked the keyboard comes up and the textfield should be on top of the keyboard but my own isn't doing what it's supposed to do. I have checked other similar questions and answers on google, stackoverflow and github but it still stays the maybe because in mine am using constraints: BoxConstraints(maxHeight: 160),
which might be what is causing it but i don't really know
This my code
class _ChatSectionState
extends State<ChatSectionState> {
List<File> images = List<File>();
getMultiFile() async {
await pickFileFromMobile("multi").then((value) {
if (value != null) {
value.paths.forEach((element) {
images.add(File(element));
});
// images = value.paths.map((path) => File(path)).toList();
}
});
setState(() {});
}
@override
Widget build(BuildContext context) {
return SafeArea(
child: Scaffold(
appBar: AppBar(...,
body: Container(
height: double.infinity,
child: Stack(
children: [
Padding(
padding: EdgeInsets.only(bottom: 50),
child: Container(
child: ListView.builder(
itemCount: 10,
reverse: true,
shrinkWrap: true,
physics: ScrollPhysics(),
itemBuilder: (ctx, idx) {...
///...
),
),
),
///This is the part that hides behide the keyboard when it appears which i want to show on top
Align(
alignment: Alignment.bottomCenter,
child: Container(
decoration: BoxDecoration(
color: white,
border: Border(
top: BorderSide(
color: grey[400],
width: .7,
),
bottom: BorderSide(
color: grey[400],
width: .7,
)),
),
constraints: BoxConstraints(maxHeight: 160), //This is the box contraints
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
mainAxisSize: MainAxisSize.min,
children: [
(images.length < 1)
? SizedBox(height: 0)
: Expanded(
child: ListView.builder(
shrinkWrap: true,
scrollDirection: Axis.horizontal,
physics: ScrollPhysics(),
padding: EdgeInsets.symmetric(
vertical: 7, horizontal: 10),
itemCount: images.length,
itemBuilder: (ctx, idx) {
return Container(
///... This is to show a image from file width a height of 100
);
},
),
),
Container(
decoration: BoxDecoration(
border: Border(
top: BorderSide(
color: grey[300],
width: .5,
)),
),
child: Row(children: [
Container(
margin: new EdgeInsets.symmetric(horizontal: 8.0),
child: new IconButton(
icon: new Icon(Icons.image),
onPressed: () => getMultiFile(),
color: primary,
),
),
Flexible(
child: Container(
child: TextFormField(
//controller: messageEditingController,
style: TextStyle(color: nBlack, fontSize: 15.0),
decoration: InputDecoration.collapsed(
hintText: 'Type a message',
hintStyle: TextStyle(color: grey),
),
onFieldSubmitted: (value) {},
),
),
),
Container(
margin: new EdgeInsets.symmetric(horizontal: 8.0),
child: new IconButton(
icon: new Icon(Icons.send),
onPressed: () {},
color: primary,
),
),
]),
),
],
),
),
)
],
),
),
resizeToAvoidBottomInset: false,
));
}
}
Please how can I make it work cause i have checked different pages still does give me what i want. I also tried this [answer][1]

I use another way. resizeToAvoidBottomInset: true and do some changes for lifting widgets top of keyboard.
bottom = MediaQuery.of(context).viewInsets.bottom;
Scaffold( resizeToAvoidBottomInset: ture, body: SingleChildScrollView( reverse:true, child: Padding( padding: EdgeInsets.only(bottom: bottom), child: ... )));
if you decrease space from keyboard to last widget use MediaQuery.of(context).viewInsets.bottom/2 e.x.

You can change resizeToAvoidBottomInset: true,
for scaffold.
It will shrink the whole scaffold
when keyboard is opened.
