Hi I am trying to i have a listview.builder which renders custom card design that i create the problem is that i want to disable button on the card on which user tap but it end up disabling all the cards button
here is the code
Expanded(
child: ListView.builder(
itemCount: list.length,
itemBuilder: (context, i) {
return CardDesign(
index: i,
infolist: list,
buttonOnTap: () async {
await updateJoin(list[i].joined += 1, list[i].id);
setState(() {});
},
onPressed: () {
Navigator.push(
context,
MaterialPageRoute(
builder: (context) => DetailsScreen(
tournamentinfo: list[i],
),
),
);
},
);
}),
the buttonOnTap Method is the one that i want to disable but only for that Specific button in the list and only for that user

When the item in the listview is clicked, I want to move the information to the bottom sheet, but I couldn't find the way.
Navigator.push(
context,
MaterialPageRoute(
builder: (context) => customBottomSheet(context),
),i tried but it didn't work how can i solve this problem
return Expanded(
child: ListView.builder(
shrinkWrap: true,
scrollDirection: Axis.vertical,
itemCount: coinListForDisplay.length,
itemBuilder: (context, index) {
return InkWell(
onTap: (() {
customBottomSheet(context);
}),
child: ListViewCard(
name: coinListForDisplay[index].name,
symbol: coinListForDisplay[index].symbol,
imageUrl: coinListForDisplay[index].imageUrl,
price:
coinListForDisplay[index].price.toDouble(),
change:
coinListForDisplay[index].change.toDouble(),
changePercentage: coinListForDisplay[index]
.changePercentage
.toDouble(),
),
);
}),
);```
You can pass data in parameters like this.
In you custom bottom sheet, use
CustomBottomSheet(BuildContext context,yourData){
//Your code
}
And in your onTap function use
CustomBottomSheet(context,yourData);
I have a simple list of ListTile s that I nested in Slidable widget using the flutter_slidable package. However there is one issue that when I use the delete button, the item stays on the screen, even though it is successfully removed from the list (If i make a hot reload, it will actually get removed from screen). I tried to add a setState method inside the onPressed function but I cannot add it because the SlidableAction widget is a stateless widget. How can I make the item disappear when I tap on this button?
Here is a small video demonstration. I delete two lists with the delete button. They stay on the screen. I go home screen and come back to see they got deleted.

Here is my code:
Expanded(
child: ListView.builder(
itemCount: likedNames.length,
itemBuilder: (context, index) {
return Slidable(
key: const ValueKey(0),
endActionPane: ActionPane(
motion: ScrollMotion(),
dismissible: DismissiblePane(onDismissed: () {
likedNames.remove(likedNames[index]);
}),
children: [
SlidableAction(
onPressed: (context) {
likedNames.remove(likedNames[index]); // <- this is the part where I want to do the removing of the item
},
label: 'Delete',
backgroundColor: AppColors.error,
),
],
),
child: ListTile(
onTap: () {},
title: Text(likedNames[index].name),
trailing: Icon(Icons.chevron_right),
),
);
}),
),
onPressed: (context) {
setState() => likedNames.remove(likedNames[index])
},
I've used this solution:
onPressed: (BuildContext context) async {
await Provider.of<MyList>(context, listen: false)
.remove(MyList[index]);
}
MyList is a separate class:
class MyList extends ChangeNotifier
Whit this methods:
final List<String> _myList = [];
List<String> get items => _myList;
.
.
.
Future<bool> remove(String item) async {
_myList.remove(item);
notifyListeners();
return true;
}
i'm pretty new in Flutter. So i wanted to ask you guys, is it possible using FirebaseAnimatedList to make it pop another window when user presses the list item. I have a feeling that it not be possible to do it, would be great if someone could explain it.
child: FirebaseAnimatedList(
query: dbRef,
itemBuilder: (BuildContext context, DataSnapshot snapshot,
Animation<double> animation, int index) {
Map contact = snapshot.value;
return _buildContactItem(contact: contact);
},
),
Instance of onTap code snippet
onTap: () {
Navigator.push(
context,
MaterialPageRoute(builder: (context) => ItemPage(uid: widget.uid)),
);
},
)
If I understand u well, u want to make onPress method for each listItem?
just wrap your widget with Inkwell inside your itembuilder.
For example:
_buildContactItem(Contact contact){
return InkWell(
onTap: () {
Navigator.push(
context,
MaterialPageRoute(builder: (context) => ItemPage(uid: widget.uid)),
);
},
child: yourChildWidgetsHere
}
Try this, I hope it will help you!

I want each list item to have its own route .I have attached a screenshot. My list view is customized, each item has its own name
Your question doesn't explain much, but rather than listview use listview.builder and then you can return any widget and pass your route based on itemindex.
ListView.builder(
itemCount: 10, *//Number of items in your static or dynamic*
itemBuilder: (context, index) {
return YourNewCommonWidgetForEveryItem(index);
},
),
For example I've to navigate the first item to somewhere else
Widget YourNewCommonWidgetForEveryItem(int Index){
return GestureDetector(
onTap:()=> index==0 ? locationtofirstItem : defaullt,
child: yourDesign(),
),
}
OfCourse the Above method won't work if you don't know where to navigate which item.
body: new ListView(
padding: const EdgeInsets.all(20.0),
children: List.generate(choices.length, (index) {
return Center(
child: ChoiceCard(
choice: choices[index],
item: choices[index],
onTap: () {
Navigator.push(
context,
MaterialPageRoute(
builder: (context) => Detail(choice: choices[index])),
);},),);}))
When the user clicks the FAB, i want it to create a new Card widget wrapped in a GestureDetector. I have created a list of type widget and also created a function with a setState to add to the list and display it in a SliverGrid. but when i click the FAB, it doesnt seem to be adding.
Could i get a small guide on how to add a Card using an FAB. (or adding any type of widget in a SliverGrid).
the list : List<Widget> cardList = <Widget>[];
function for adding items to the list :
void addItems() async{
setState(() {
cardList.insert(0, GestureDetector(
onTap: () async {
await Navigator.push( context, MaterialPageRoute(
builder: (context) => TodoList(), // this just navigates to another screen ; not important in this question
)
);
},
child: Card(
child:Center(child: whitefontstylemont(text: "project 1", size:20,)) //this is just a custom TextStyle
),
));
});
}
the floating action button which adds a new Card to the list :
floatingActionButton: FloatingActionButton( // this is inside a Scaffold
onPressed: ()async {
setState(() {
addItems();
});
},
heroTag: "btn2",
child: Icon(Icons.add, color: Color(whitecolor),), backgroundColor: Color(redcolor),),
the SliverGrid where i want a new card to be displayed :
SliverGrid(
gridDelegate: SliverGridDelegateWithFixedCrossAxisCount(
crossAxisCount: 2
),
delegate: new SliverChildBuilderDelegate((context, index) {
return cardList[index];
},
childCount: cardList.length // this is where i want a new Card to be displayed
)
),
