如何在我的视图模型命令方法中获取GestureRecognizer命令的参数？

// 在视图模型中定义命令和参数属性
public class ViewModel
{
    public ICommand Command { get; set; }
    public object CommandParameter { get; set; }

    public ViewModel()
    {
        Command = new Command(CommandMethod);
    }

    private void CommandMethod(object parameter)
    {
        // 在这里处理GestureRecognizer命令，可以通过parameter参数获取命令的参数
        // ...
    }
}

// 在视图中使用GestureRecognizer和绑定
public class MyView : ContentView
{
    public MyView()
    {
        var tapGestureRecognizer = new TapGestureRecognizer();
        tapGestureRecognizer.SetBinding(TapGestureRecognizer.CommandProperty, "Command");
        tapGestureRecognizer.SetBinding(TapGestureRecognizer.CommandParameterProperty, "CommandParameter");

        GestureRecognizers.Add(tapGestureRecognizer);
    }
}
