How to add or remove an item from .NET MAUI ListView(SfListView)?
The .NET MAUI ListView (SfListView) allows you to add or remove items by updating the collection bound to the SfListView.ItemsSource from the ViewModel.
XAML
ViewModel commands are bound to the view for adding or removing an item.
<StackLayout>
<Grid HeightRequest="50" ColumnSpacing="5" Padding="5">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<Button Text="Add item" Grid.Column="0" Command="{Binding AddCommand}"/>
<Button Text="Delete last item" Grid.Column="1" Command="{Binding DeleteCommand}"/>
</Grid>
<listView:SfListView x:Name="listView" ItemSize="70" ItemsSource="{Binding ContactsInfo}" VerticalOptions="FillAndExpand">
...
</listView:SfListView>
</StackLayout>
C#

var details = new Contacts()
{
ContactName = CustomerNames[r.Next(1, 50)],
ContactNumber = r.Next(100, 400).ToString() + "-" + r.Next(500, 800).ToString() + "-" + r.Next(1000, 2000).ToString(),
