How to highlight the cell value when searching in Flutter DataTable (SfDataGrid)?

In this article, we will show you how to highlight the cell value when searching in Flutter DataTable.

Initialize the SfDataGrid widget with all the necessary properties. Within the DataGridSource.buildRow(), if searchController.text is equal to the corresponding cell value, you should add the appropriate style to highlight the text in the cell. Additionally, remember to call notifyListeners when the searchController.text changes, to refresh the DataGrid and apply highlighting to the searched cell value.

Widget searchField() {
    return Container(
      width: 200,
      height: 50,
      decoration: BoxDecoration(
        border: Border.all(
          color: Colors.grey,
          width: 1.0,
        ),
        borderRadius: BorderRadius.circular(8.0),
      ),
      child: TextField(
        controller: employeeDataSource.searchController,
        onChanged: (v) {
          employeeDataSource.refreshDataGridSource();
          initiateScrolling();
        },
        decoration: const InputDecoration(
          hintText: "Search",
        ),
      ),
    );
  }


class EmployeeDataSource extends DataGridSource {
  …
  
  final searchController = TextEditingController();
  
  @override
  DataGridRowAdapter buildRow(DataGridRow row) {
    return DataGridRowAdapter(
      cells: row.getCells().map<Widget>((e) {
        TextStyle? getTextStyle() {
          if (searchController.text.toLowerCase() ==
              e.value.toString().toLowerCase()) {
            return TextStyle(
                fontWeight: FontWeight.bold,
                color: Colors.pinkAccent,
                background: Paint()..color = Colors.yellow);
          } else {
            return null;
          }
        }

        return Container(
          alignment: Alignment.center,
          padding: const EdgeInsets.all(8.0),
          child: Text(
            e.value.toString(),
            style: getTextStyle(),
          ),
        );
      }).toList(),
    );
  }
