MinimumHeightRequest is used to override the results of a call to VisualElement.GetSizeRequest (double, double) by setting the minimum height property. This causes overflow handling to shrink this element to its minimum height before elements who do not have a minimum size set.

The following example sets the MinimumHeightRequest to enable an image to shrink below it's normal size.

  void Build (string veryLongString)
  {
    var label = new Label {Text = veryLongString};
    var image = new Image {Source = "image500x500.png"};

    image.MinimumHeightRequest = 20;
    Content = new StackLayout {
      Children {
        label,
        image
      }
    };
  }
