                    <StackLayout x:Name="stackview"  BackgroundColor="Red"  />

               </StackLayout>              
            </ScrollView>                              
        </StackLayout>
      
    </ContentPage.Content>

Codebehind Part

public partial class WebViewTest : ContentPage
 {
        
        string url = "https://en.wikipedia.org/wiki/Wikipedia";
        public WebViewTest( )
        {
            InitializeComponent();

            var browser = new MyWebView
            {
                Source = url,
            };
          
            if (url == "")
            {
                browser.IsVisible = false;             
            }
            else
            {
               
                stackview.Children.Add(browser);
            }

        }
}

For Custom renderer, I'm following this code Custom renderer code

CodePudding user response：

If you just want the webview to fix the blank space in your layout. You can just get the height of the space and set it as the webview's HeightRequest.

Such as:

 protected override void OnAppearing()
    { 
        browser.HeightRequest = (belowcontrol.Y - abovecontrol.Y);
        base.OnAppearing();
    }
