Xamarin表单按钮在网格内变平

嗨,我试图实现一个底部按钮栏没有边距,但行为不是预期的。

我的纽扣在堆叠布局时变平了,看起来不错,但有边距。

你还可以看到,在第一个图像的“D”图像是削减底部,似乎有一个间距之间的滚动视图和按钮,我如何才能删除它?

我所拥有的

var consultorButtons = new Grid()
{
    VerticalOptions = LayoutOptions.EndAndExpand,
    HorizontalOptions = LayoutOptions.FillAndExpand,
    Margin = new Thickness(0),
    Padding = new Thickness(0),
    RowSpacing = 0,
    ColumnSpacing = 0,

};

consultorButtons.RowDefinitions.Add(new RowDefinition { Height = new GridLength(1, GridUnitType.Star) });
consultorButtons.ColumnDefinitions.Add(new ColumnDefinition { Width = new GridLength(1, GridUnitType.Star) });
consultorButtons.ColumnDefinitions.Add(new ColumnDefinition { Width = new GridLength(1, GridUnitType.Star) });

consultorButtons.Children.Add(
    new Button
    {
        Text = "TELEFONAR",
        BackgroundColor = Color.FromHex("#21c9ae"),
        HorizontalOptions = LayoutOptions.FillAndExpand,
        VerticalOptions = LayoutOptions.FillAndExpand,
        Margin = new Thickness(0),
        FontSize = 14
    }, 0, 0);

consultorButtons.Children.Add(
    new Button
    {
        Text = "EMAIL",
        BackgroundColor = Color.FromHex("#272f57"),
        HorizontalOptions = LayoutOptions.FillAndExpand,
        VerticalOptions = LayoutOptions.FillAndExpand,
        TextColor = Color.White,
        Margin = new Thickness(0),
        FontSize = 14
    }, 1, 0);
