How to add fixed header (freeze panes) in Flutter DataTable (SfDataGrid)?

The Syncfusion Flutter DataTable widget provides the support to set the fixed header is also known as freeze rows (top and bottom) or columns (right and left) by using following properties,

• frozenRowsCount,
• footerFrozenRowsCount,
• frozenColumnsCount,
• footerFrozenColumnsCount.

The freeze row and freeze column are shown with the elevation effect. You can change the elevation value in SfdataGridThemeData using frozenPaneElevation property.

Fixed header (Freeze rows)

The rows can be frozen in view at top and bottom by setting the frozenRowsCount and footerFrozenRowsCount properties.

  
@override
  Widget build(BuildContext context) {
    return Scaffold(
        appBar: AppBar(
          title: Text('Freeze Pane Demo'),
        ),
        body: SfDataGrid(
            source: freezePanesDataGridSource,
            frozenRowsCount: 1,
            columns: getColumns()));
  }
 

The following code example shows how to freeze a row at bottom by setting the footerFrozenRowsCount property.

 
  @override
  Widget build(BuildContext context) {
    return Scaffold(
        appBar: AppBar(
          title: Text('Freeze Pane Demo'),
        ),
        body: SfDataGrid(
            source: freezePanesDataGridSource,
            footerFrozenRowsCount: 1,
            columns: getColumns()));
  }
 

Fixed column (Freeze column)

The columns can be frozen in view at left and right by setting the frozenColumnsCount and footerFrozenColumnsCount properties.

 
  @override
  Widget build(BuildContext context) {
    return Scaffold(
        appBar: AppBar(
          title: Text('Freeze Pane Demo'),
        ),
        body: SfDataGrid(
            source: freezePanesDataGridSource,
           frozenColumnsCount: 1,
            columns: getColumns()));
  }

The following code example shows how to freeze a column at right by setting footerFrozenColumnsCount property.

  
@override
  Widget build(BuildContext context) {
    return Scaffold(
        appBar: AppBar(
          title: Text('Freeze Pane Demo'),
