@override
Widget build(BuildContext context) {
  return SfDataGrid(
      source: _employeeDataSource,
      footerHeight: 60.0,
      footer: Container(
          color: Colors.grey[400],
          child: Center(
              child: Text(

            style: TextStyle(fontWeight: FontWeight.bold),
          ))),
      columns: <GridColumn>[
        GridColumn(
            columnName: 'id',
            label: Container(
                padding: EdgeInsets.all(8.0),
                alignment: Alignment.center,

By default, the additional row will be displayed below the last row. To show the additional row always on the view bottom, simply set the SfDataGrid.footerFrozenRowsCount property to 1.

@override
Widget build(BuildContext context) {
  return SfDataGrid(
      source: _employeeDataSource,
      footerFrozenRowsCount: 1,
      footer: Container(
          color: Colors.grey[400],
          child: Center(
              child: Text(
            'FOOTER VIEW',
            style: TextStyle(fontWeight: FontWeight.bold),
          ))),
      columns: <GridColumn>[
        GridColumn(
            columnName: 'id',
            label: Container(
                padding: EdgeInsets.all(8.0),
                alignment: Alignment.center,
                child: Text(
                  'ID',
                ))),
        GridColumn(
            columnName: 'name',
            label: Container(
                padding: EdgeInsets.all(8.0),
                alignment: Alignment.center,
                child: Text('Name'))),
