Отображение данных (фильтрация)

Question

хочу вывести данные в CollectionView, данные которые имеют state = false с использованием CommunityToolkit.Mvvm, но не совсем понимаю как это сделать.

Model

public class Task
{
    public string Title { get; set; }
    public string Text { get; set; }
    public bool State { get; set; }
    public DateTime CreateDate { get; set; }
}

View

<CollectionView ItemsSource="{Binding Tasks}">
                    <CollectionView.ItemTemplate>
                        <DataTemplate>
                            <SwipeView Margin="0,0,0,10">
                                <SwipeView.LeftItems>
                                    <SwipeItems Mode="Execute">
                                        <SwipeItem 
                                            Text="Done"
                                            BackgroundColor="LightGreen"
                                            Command="{Binding Source={RelativeSource AncestorType={x:Type viewmodel:ToDoViewModel}}, Path=StateDoneCommand}"
                                            CommandParameter="{Binding .}"/>
                                    </SwipeItems>
                                </SwipeView.LeftItems>
                            &lt;SwipeView.RightItems&gt;
                                &lt;SwipeItems&gt;

                                    &lt;SwipeItem 
                                        Text=&quot;Delete&quot;
                                        BackgroundColor=&quot;LightPink&quot;

ViewModel

    int count = 1;
    public ToDoViewModel()
    {
        tasks = new ObservableCollection&lt;Task&gt;();
    }

    [RelayCommand]
