Hi Roberto,

Thanks for contacting Syncfusion support.

Please ensure that you have set the following properties,

We suspect that you might not set the allowSwiping property. We have also published the SB sample in below GitHub location,

https://github.com/syncfusion/flutter-examples/blob/master/lib/samples/datagrid/swiping/datagrid_swiping.dart

If you still couldn’t swipe the rows, please share your code or example project. We will check and provide you the solution as early as possible.

Regards,

Neelakandan

Hi Neelakandan,

Thank you for the super fast reply. Here is my code for the data grid not including the data source. Everything else works except the swipe issue. I also just confirmed that swiping does not work on both iOS emulator and android emulator. I also tried a physical iPhone- does not work. Any ideas?

```
class ExpenseDataGrid extends StatefulWidget {
@override
_ExpenseDataGridState createState() => _ExpenseDataGridState();
}

class _ExpenseDataGridState extends State<ExpenseDataGrid> {
@override
Widget build(BuildContext context) {
return Consumer<ExpenseData>(
builder: (context, expenseData, child) {
var expenseDataSource =
ExpenseGridSource(expenseData: expenseData.getExpenseList());
return Scaffold(
body: SafeArea(
///
/// TODO: Handle no swipe problem
///

child: SfDataGrid(
allowSwiping: true,
swipeMaxOffset: 100.0,
source: expenseDataSource,
columnWidthMode: ColumnWidthMode.fill,
startSwipeActionsBuilder: (context, row) {
return GestureDetector(
child: Container(
width: 100.0,
color: Colors.orange,
child: Center(
child: Icon(
Icons.edit,
),
),
),
onTap: () {
int index = expenseDataSource._expenseData.indexOf(row);
EditExpense(index: index);
},
);
},
endSwipeActionsBuilder: (context, row) {
return GestureDetector(
child: Container(
width: 100.0,
color: Colors.red,
child: Center(
child: Icon(
Icons.delete,
),
),
),
onTap: () {
int index = expenseDataSource._expenseData.indexOf(row);
Provider.of<ExpenseData>(context).deleteExpense(index);
},
);
},
columns: <GridColumn>[
GridTextColumn(
columnName: 'item',
label: Container(
color: Colors.red,
padding: EdgeInsets.all(8.0),
alignment: Alignment.centerLeft,
child: Text(
'Item',

child: Text(

GridTextColumn(

),
),
);
},
);
}
}

Hi Renuga,

Looks like this problem is a problem with how I'm loading data from Provider/Consumer. Its exactly related to my other issue and is causing it. As Here.
Possibly I could get some help on this once I wrap my head around how to even propose it? That would be super helpful.

Also I have to say that customer support here is phenomenal!

Hi Roberto,   
  
Thanks for your feedback on customer support.   
 
We hope that our provided simple swiping example is working fine at your end. As you updated, this may be the problem in Provider/Consumer data binding. As Balasubramani has requested the details in below forum, please provide the details in below forum. So that, the swiping problem will be resolved. 
  
  
Please let us know if you need further assistance on swiping example. 
 
Regards,
