Hi @abdulrehmananwar

The editing will be ended when you call the notifyListeners() externally to update the cell data. So, instead of calling the notifyListeners(), just use the notifyDataSourceListeners method to update the specific cell. Here, we have provided the sample as per your requirement. Please refer to the below sample and code snippet,

Code Snippet:

void onCellSubmit(DataGridRow dataGridRow, RowColumnIndex rowColumnIndex,
      GridColumn column) {
    final dynamic oldValue = dataGridRow
            .getCells()
            .firstWhereOrNull((DataGridCell dataGridCell) =>
                dataGridCell.columnName == column.columnName)
            ?.value ??
        '';

    final int dataRowIndex = dataGridRows.indexOf(dataGridRow);

    if (newCellValue == null || oldValue == newCellValue) {
      return;
    }
…
    //Calls all the datagrid source listeners. Call this method whenever the underlying data is added or removed.
    //If the value of the specific cell is updated,
    //call this method with RowColumnIndex argument where it refers the corresponding row and column index of the cell

    notifyDataSourceListeners(rowColumnIndex: RowColumnIndex(dataRowIndex, 4));  
  }
