How to customize the background color of the rows per page dropdown menu in Flutter DataGrid?

In this article, you can learn about how to customize the color of the checkbox in Flutter DataGrid.

Initialize the SfDataGrid widget with all the required properties. You can customize the background color of the dropdown menu by using the Theme widget. To achieve this, wrap the SfDataPager as a child of the Theme widget. The copyWith method is used to create a copy of the current theme data and set the desired values for canvasColor in the Theme class.

@override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text('Syncfusion Flutter DataGrid'),
      ),
      body: LayoutBuilder(builder: (context, constraint) {
        return Column(children: [
          SizedBox(
              height: constraint.maxHeight - _dataPagerHeight,
              width: constraint.maxWidth,
              child: _buildDataGrid(constraint)),
          SizedBox(
            height: _dataPagerHeight,
            child: Theme(
              data: Theme.of(context).copyWith(canvasColor: Colors.red),
              child: SfDataPager(
                delegate: employeeDataSource,
                pageCount: _pageEmployee.length / _rowsPerPage,
                availableRowsPerPage: const [2, 5, 10],
                onRowsPerPageChanged: (value) {
                  setState(() {
                    if (value != null) {
                      _rowsPerPage = value;
                    }
                  });
                },
                direction: Axis.horizontal,
              ),
            ),
          )
        ]);
      }),
    );
  }
