Hi I'm working on the Flutter project I'm having an issue with the flutter ListView button, So right now it looks the same what I wanted but it doesn't work how I wanted
So if you see the above image if I click then tick overlay appears for that I need to setState() but the issue is right now to get that overlay tick I need to tap twice I don't understand how to fix this issue or is there any widget button which onclick overlay I checked most of them but most of them didn't work or I was not aware of? Inside container, I have 14 same columns with numbers 1-14 I'll make it more compact but first I need to fix this issue here is the code.
`bool _pressed = false;
int _btnIndex = 0;
TabBarView(children: <Widget>[
Container(
height: 300,
// padding: EdgeInsets.only(bottom: 10),
padding: EdgeInsets.all(10),
color: Colors.white,
child: ListView(
padding: EdgeInsets.all(6),
scrollDirection: Axis.horizontal,
children: <Widget>[
Column(
crossAxisAlignment: CrossAxisAlignment.center,
mainAxisAlignment: MainAxisAlignment.spaceAround,
children: <Widget>[
Container(
alignment: Alignment.center,
child: Padding(
padding: const EdgeInsets.all(6.0),
child: Material(
elevation: 4.0,
shape: CircleBorder(),
clipBehavior: Clip.hardEdge,
color: !_pressed && _btnIndex == 1
? Colors.red
: Colors.white54,
child: Ink.image(
image: AssetImage('assets/images/colosseum.jpg'),
fit: BoxFit.cover,
colorFilter: _pressed && _btnIndex == 1
? ColorFilter.mode(
Colors.black87,
BlendMode.darken,
)
: null,
width: 60.0,
height: 60.0,
child: InkWell(
// splashColor: Colors.green,
focusColor: Colors.red,
highlightColor: Colors.white60,
// overlayColor: MaterialStateColor(),
child: _pressed && _btnIndex == 1
? Icon(
Icons.check,
color: Colors.white,
)
: null,
// onDoubleTap: () {
// _pressed = !_pressed;
// },
onTap: () {
setState(() {
_pressed = !_pressed;
_btnIndex = 1;
});
// _pressed = true;
print('I tapped no 1');
},
),
),
),
),
),
Container(
alignment: Alignment.center,
child: Text('10'),
),
],
),
]),
),
]);`
just use Listview.builder for this and inside that use GestureDetector inside Builder to change selected item
first take a variable to track selected index
int selected;
then make a listView Builder Widget
ListView.builder(
itemCount:5,
scrollDirection: Axis.horizontal,
itemBuilder:(ctx,index){
return GestureDetector(
onTap:(){
selected = index;
setState((){});
}
child: YourWidget(isSelected:this.selected == index);
);
}
)
just write logic for displaying tick in YourWidget image when isSelected is true
Hey @user2572661 may be when you touch container may not interact as what you want you can use ListView.builder()
with scroll direction horizontal also there is a Widget you can use it onTap:
to change state or logic call GestureDetector()
. Although can you please share some more code so that i can understand and rectify your problem.
