Xaml.cs
The following code demonstrates how to customize the table summary row using a custom renderer in SfDataGrid.

public partial class MainPage : ContentPage
{
    public MainPage()
    {
        InitializeComponent();
        sfGrid.CellRenderers.Remove("TableSummary");
        sfGrid.CellRenderers.Add("TableSummary", new TableSummaryCellRenderer());
    }
}
public class TableSummaryCellRenderer : DataGridTableSummaryCellRenderer
{
    protected override void OnSetCellStyle(DataColumnBase dataColumn)
    {
        base.OnSetCellStyle(dataColumn);

        if (dataColumn.ColumnElement != null && dataColumn.ColumnElement.Content is SfDataGridLabel label)
        {
            dataColumn.ColumnElement.Background = Colors.SkyBlue;

            label.HorizontalTextAlignment = TextAlignment.Start;
            label.FontSize = 16;
            label.FontAttributes = FontAttributes.Bold;
            label.TextColor = Colors.White;
        }
    }
