Paging in Flutter DataGrid (SfDataGrid)

26 Jun 202324 minutes to read

The Datagrid interactively supports the manipulation of data using the SfDataPager control. This provides support to load data in segments when dealing with large volumes of data. The SfDataPager can be placed above or under based on the requirement to easily manage data paging.

The Datagrid performs paging of data using the SfDataPager. To enable paging, follow this procedure

Create a new SfDataPager widget, and set the SfDataGrid.DataGridSource to the SfDataPager.delegate property.
Set the number of pages required to be displayed in the data pager by setting the SfDataPager.pageCount property.
Set the number of buttons that should be displayed in view by setting the SfDataPager.visibleItemsCount property.
Load the data for a specific page in the handlePageChange method. This method is called for every page navigation from the data pager.

NOTE

The SfDataPager.visibleItemsCount property default value is 5.

The following code example illustrates using the SfDataPager with the Datagrid control:

DART
import 'package:intl/intl.dart';

final int _rowsPerPage = 15;

final double _dataPagerHeight = 60.0;

List<OrderInfo> _orders = [];

List<OrderInfo> _paginatedOrders = [];

final OrderInfoDataSource _orderInfoDataSource = OrderInfoDataSource();

@override
Widget build(BuildContext context) {
  return LayoutBuilder(builder: (context, constraint) {
    return Column(children: [
      SizedBox(
          height: constraint.maxHeight - _dataPagerHeight,
          width: constraint.maxWidth,
          child: _buildDataGrid(constraint)),
      Container(
          height: _dataPagerHeight,
          child: SfDataPager(
            delegate: _orderInfoDataSource,
            pageCount: _orders.length / _rowsPerPage,
            direction: Axis.horizontal,
          ))
    ]);
  });
}
Widget _buildDataGrid(BoxConstraints constraint) {
  return SfDataGrid(
      source: _orderInfoDataSource,
      columnWidthMode: ColumnWidthMode.fill,
      columns: <GridColumn>[
        GridColumn(
            columnName: 'orderID',
            label: Container(
                padding: EdgeInsets.symmetric(horizontal: 16.0),

                  'Order ID',
                  overflow: TextOverflow.ellipsis,
                ))),
        GridColumn(

Callbacks

The SfDataPager provides the onPageNavigationStart and onPageNavigationEnd callbacks to listen to the page navigation at the widget level.

Typically, these callbacks are used to show and hide the loading indicator.

DART
@override
Widget build(BuildContext context) {
  return Scaffold(body: LayoutBuilder(builder: (context, constraints) {
    return Row(children: [
      Column(children: [
        SizedBox(
            height: constraints.maxHeight - 60,
            width: constraints.maxWidth,
            child: _buildDataGrid(constraints)),
        Container(
            height: 60,
            width: constraints.maxWidth,
            child: SfDataPager(
                pageCount: _orders.length / _rowsPerPage,
                direction: Axis.horizontal,
                onPageNavigationStart: (int pageIndex) {
                  //You can do your customization
                },
                delegate: _orderInfoDataSource,
                onPageNavigationEnd: (int pageIndex) {
                  //You can do your customization
                }))
      ])
    ]);
  }));
}

Asynchronous data loading

You can load the data asynchronously to the SfDataPager by overriding the handlePageChange method and await the method while loading the data.

You can use onPageNavigationStart and onPageNavigationEnd callbacks to show and hide the loading indicator when navigating between pages.

In the below example, we have set await for 2000ms and displayed the loading indicator until 2000ms.

DART
import 'package:intl/intl.dart';

bool showLoadingIndicator = true;

@override
Widget build(BuildContext context) {
  return Scaffold(body: LayoutBuilder(builder: (context, constraints) {
    return Row(children: [
      Column(children: [
        SizedBox(
            height: constraints.maxHeight - 60,
            width: constraints.maxWidth,
            child: _buildStack(constraints)),
        Container(
            height: 60,
            width: constraints.maxWidth,
            child: SfDataPager(
                pageCount: _orders.length / _rowsPerPage,
                direction: Axis.horizontal,
                onPageNavigationStart: (int pageIndex) {
                  setState(() {
                    showLoadingIndicator = true;
                  });
                },
                delegate: _orderInfoDataSource,
                onPageNavigationEnd: (int pageIndex) {
                  setState(() {
                    showLoadingIndicator = false;
                  });
                }))
      ])
    ]);
  }));
}

Widget _buildStack(BoxConstraints constraints) {
  List<Widget> _getChildren() {
    final List<Widget> stackChildren = [];
    stackChildren.add(_buildDataGrid(constraints));

    if (showLoadingIndicator) {
      stackChildren.add(Container(
          color: Colors.black12,
          width: constraints.maxWidth,
          height: constraints.maxHeight,

The SfDataPager provides the support to navigate between the pages programmatically using a controller with the following options.

The following code example shows how to navigate the previous page programmatically,

DART
DataPagerController _controller = DataPagerController();

@override
Widget build(BuildContext context) {
  return Scaffold(body: LayoutBuilder(builder: (context, constraint) {
    return Column(children: [
      MaterialButton(
        onPressed: () {
          _controller.previousPage();
        },
        child: Text('Move Previous page'),
      ),
      SizedBox(
          height: constraint.maxHeight - 120,
          width: constraint.maxWidth,
          child: _buildDataGrid(constraint)),
      Container(
          height: 60,
          child: Align(
              alignment: Alignment.center,
              child: SfDataPager(
                delegate: _orderInfoDataSource,
                initialPageIndex: 2,
                controller: _controller,
                pageCount: _orders.length / _rowsPerPage,
                direction: Axis.horizontal,
              )))
    ]);
  }));
}

Show the dropdown button option to select a different number of rows per page by defining the onRowPerPageChanged callback. If it is null, no option will be provided to select a different number of rows per page.

Use the availableRowsPerPage property to define the list of numbers to be displayed in the drop-down. The default value of the availableRowsPerPage property is [10,15,20].

NOTE
You can view dropdown button option by horizontally scrolling the DataPager. The dropdown button option is not supported, if the direction is vertical.

DART
int _rowsPerPage=10;
  List<Employee> employees = <Employee>[];
  late EmployeeDataSource employeeDataSource;
  double datapagerHeight = 70.0;

flutter datapager with rowsperpage

Orientation

SfDataPager allows you to arrange the child elements either horizontally or vertically. This can be achieved by using the direction Property. direction is an Enum type.

Enum	Description
horizontal	This is the default enum value for direction. Arranges all the navigation buttons and numeric buttons horizontally.
vertical	Arranges all the navigation buttons and numeric buttons vertically by setting Axis.vertical to direction property.

Appearance

SfDataPager allows customizing the appearance of the data pager using the SfDataPagerThemeData in SfDataPagerTheme. The SfDataPager should be wrapped inside the SfDataPagerTheme.

Import the following class from the syncfusion_flutter_core package.

DART
import 'package:syncfusion_flutter_core/theme.dart';

The following code example illustrates using SfDataPagerThemeData with the data pager control

DART
@override
Widget build(BuildContext context) {
  return Scaffold(
    body: SfDataPagerTheme(
      data: SfDataPagerThemeData(
        itemColor: Colors.white,
        selectedItemColor: Colors.lightGreen,
        itemBorderRadius: BorderRadius.circular(5),
        backgroundColor: Colors.teal,
      ),
      child: SfDataPager(
        delegate: _orderInfoDataSource,
        pageCount: _orders.length / _rowsPerPage,
        direction: Axis.horizontal,
      ),
    ),
  );
}

flutter datapager with customization

Set the padding between page items

The padding between the page items including navigation page items such as first, last, previous and next can be changed by using the itemPadding property.

DART
@override
  Widget build(BuildContext context) {
    return Scaffold(
        appBar: AppBar(
          title: const Text('Syncfusion Flutter DataGrid'),
        ),
        body: SfDataPager(
            itemPadding: EdgeInsets.all(8.0),
            pageCount: 5,
            delegate: employeeDataSource,
          ),
        );
  }

NOTE

The default value of SfDataPager.itemPadding is 5.0.

Set the height and width of the page items

The default width and height of the page items are 50 and 50, respectively. For changing page number items size, use the itemWidth and itemHeight properties; for changing navigation items size such as first, last, previous, and next, use the navigationItemHeight and navigationItemWidth properties.

flutter datapager with page button resizing

Change the number of visible items (buttons) in the view

You can change the number of visible items i.e. page buttons in view by using the SfDataPager.visibleItemsCount.

DART
@override
Widget build(BuildContext context) {
  return Scaffold(
      appBar: AppBar(
        title: Text('Flutter DataGrid Sample'),
      ),
      body: LayoutBuilder(builder: (context, constraint) {
        return Column(
          children: [
            SizedBox(
                height: constraint.maxHeight - _dataPagerHeight,
                width: constraint.maxWidth,
                child: _buildDataGrid(constraint)),
            Container(
              height: _dataPagerHeight,
              child: SfDataPager(
                visibleItemsCount: 1,
                delegate: _orderInfoDataSource,
                pageCount: _orders.length / _rowsPerPage,
                direction: Axis.horizontal,
              ),
            )
          ],
        );
      }));
}

Load any widget to the page button by using the SfDataPager.pageItemBuilder.

                  child: SfDataPager(
                    pageItemBuilder: (String value) {
                      return Container(
                          child: Text(
                        value,
                        style: TextStyle(
                            fontSize: 10, fontWeight: FontWeight.w700),
                      ));
                    },
                    delegate: _orderInfoDataSource,
                    pageCount: _orders.length / _rowsPerPage,
                    direction: Axis.horizontal,
                  )))
        ]);
      }));
}

Sort all the rows instead of rows available on a page

By default, the rows on a page are sorted. To sort all the rows available for paging, do not override the handlePageChange method in the DataGridSource class. The DataGrid will automatically split the rows required for each page based on the SfDataPager.pageCount, i.e. the divided value of the DataGridRows.rows and SfDataPager.pageCount.

If you want to specifically maintain the rows required for a page, you can use the SfDataGrid.rowsPerPage property. However, make sure that you do not override the handlePageChange method in the DataGridSource class at the sample level.
