How to set different row height for each row in .NET MAUI ListView (SfListView)?

The .NET MAUI ListView allows you to customize the row height for each item by utilizing the QueryItemSize event. This event is triggered whenever an item comes into view, with the QueryItemSizeEventArgs argument providing relevant information, including item index, size, and a handled bool.

XAML:

<ContentPage xmlns:sfListView="clr-namespace:Syncfusion.Maui.ListView;assembly=Syncfusion.Maui.ListView">

    <ContentPage.BindingContext>
        <local:ContactsViewModel x:Name="viewModel"/>
    </ContentPage.BindingContext>

    <Grid>
        <sfListView:SfListView    x:Name="listView"  
                                  ItemSpacing="5" 
                                  ItemsSource="{Binding Items}" 
                                  SelectionMode="Multiple">
            <sfListView:SfListView.ItemTemplate>
                <DataTemplate>
                    <Grid x:Name="grid">
                        <Grid.RowDefinitions>
                            <RowDefinition Height="*" />
                            <RowDefinition Height="*" />
                        </Grid.RowDefinitions>
                        <Label  Grid.Row="0" HorizontalTextAlignment="Center" HorizontalOptions="StartAndExpand" Text="{Binding ContactName}" FontSize="18" />
                        <Label Grid.Row="1" HorizontalTextAlignment="Center" HorizontalOptions="StartAndExpand"  Text="{Binding ContactNumber}" FontSize="15" />
                    </Grid>
                </DataTemplate>
            </sfListView:SfListView.ItemTemplate>
        </sfListView:SfListView>
    </Grid>
</ContentPage>

C# :

public partial class MainPage : ContentPage
{
    public MainPage()
    {
        InitializeComponent();
        listView.QueryItemSize += ListView_QueryItemSize;
    }

    private void ListView_QueryItemSize(object sender, QueryItemSizeEventArgs e)
    {
        if (e.ItemIndex % 2 == 0)
            e.ItemSize = 50;
        else
            e.ItemSize = 100;
        e.Handled = true;
    }
}
