如何在xamarin中将可观察的集合绑定到flexlayout？

<FlexLayout x:Name="flexLayout" Direction="Row" JustifyContent="Start" AlignItems="Start">
    <!-- Add child views here -->
</FlexLayout>

public ObservableCollection<string> Items { get; set; } = new ObservableCollection<string>();

// Add items to the collection
Items.Add("Item 1");
Items.Add("Item 2");
Items.Add("Item 3");

<DataTemplate>
    <Label Text="{Binding .}" />
</DataTemplate>

<CollectionView ItemsSource="{Binding Items}" ItemTemplate="{StaticResource ItemTemplate}">
    <CollectionView.ItemsLayout>
        <FlexLayoutItemsLayout Direction="Row" JustifyContent="Start" AlignItems="Start" />
    </CollectionView.ItemsLayout>
</CollectionView>

BindingContext = this;
