Issue with SelectedValueChanged Event in PickerField

[rosaly9108]

I'm encountering an issue with the SelectedValueChanged event in a PickerField control in my MAUI application. Despite specifying SelectedValueChanged in the XAML and attempting to handle it in the corresponding event handler method, the application does not trigger the event when a selection is made in the PickerField.
<material:PickerField
x:Name="PickerType"
ItemsSource="{Binding ColumnTypes}"
SelectedItem="{Binding SelectedColumnType}"
SelectedValueChanged="OnPickerValueChanged" />

private void OnPickerValueChanged(object sender, EventArgs e)
{
Debug.WriteLine("Picker value changed!");
}
