How to get the column name on tapping a row in Flutter DataTable?

In this article, we will show you how to get the column name on tapping a row in Flutter DataTable.

Initialize the SfDataGrid widget with all necessary properties. The SfDataGrid.onCellTap callback is triggered when a cell is tapped, providing DataGridCellTapDetails for the tapped cells. Using these details, we can retrieve the respective column names.

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text('Syncfusion Flutter DataGrid'),
      ),
      body: SfDataGrid(
        source: employeeDataSource,
        onCellTap: (details) {
          String columnName = details.column.columnName;
          showDialog(
            context: context,
            builder: (BuildContext context) {
              return AlertDialog(
                title: const Text('Tapped Column Name'),
                content: Text(
                  columnName,
                  style: const TextStyle(
                      color: Colors.red, fontWeight: FontWeight.bold),
                ),
                actions: [
                  TextButton(
                    onPressed: () {
                      Navigator.of(context).pop();
                    },
                    child: const Text('OK'),
                  ),
                ],
              );
            },
          );
        },
        columnWidthMode: ColumnWidthMode.fill,
        columns: <GridColumn>[
          GridColumn(
              columnName: 'id',
              label: Container(
                  padding: const EdgeInsets.all(16.0),
                  alignment: Alignment.center,
                  child: const Text(
                    'ID',
                  ))),
          GridColumn(
              columnName: 'name',
              label: Container(
                  padding: const EdgeInsets.all(8.0),
                  alignment: Alignment.center,
                  child: const Text('Name'))),
          GridColumn(
              columnName: 'designation',
              label: Container(
                  padding: const EdgeInsets.all(8.0),
                  alignment: Alignment.center,
                  child: const Text(
                    'Designation',
                    overflow: TextOverflow.ellipsis,
                  ))),
          GridColumn(
              columnName: 'salary',
              label: Container(
                  padding: const EdgeInsets.all(8.0),
                  alignment: Alignment.center,
                  child: const Text('Salary'))),
        ],
      ),
    );
  }
