Hello I got an error while doing login page. I just code Mainpage.xaml file other files are default and I picked "blank" when creating project.
My error is:
" System.InvalidOperationException: "The class, property, or method you are attempting to use ("GradientBrush" is part of GradientBrush; to use it, you must opt-in by calling Forms.SetFlags("Brush_Experimental") before calling Forms.Init()."
I just write one file which is Mainpage.xaml. Does anybody help me how to handle my problem?

According to the documentation you need to set up experimental flags (In your target platforms projects) for some features that the development team is judging still in experimental phase, so that you acknowledge that before using them.
On android in will be in your MainActivity class, on ios in AppDelegate Class:
Forms.SetFlags("Brush_Experimental")
You can set several experimental flags at once like:
Xamarin.Forms.Forms.SetFlags(new string[] { "SwipeView_Experimental", "Shapes_Experimental", "AppTheme_Experimental" });
Note
Make sure to call SetFlags() before Xamarin.Forms.Forms.Init()

Problem with listview on Xamarin Forms iOS
Hello, I have a cross-platform app, I put a ListView with some items, on android it's all right, but on iOS there's a blank space that I'm not able to correct...
I've already reviewed the code and I can't find what's wrong.
Has anyone seen this error or already gone through it?
Here is my image:
Blank is my content page.
Yellow is my ListView.
The blue square is the blank space I can't remove.
Red is the header of my list.
Here is my code:

Add VerticalAlignment to the ListView and set it to be either Top or Stretch. Possibly do the same for StackLayout.
You can optionally remove the parent Grid if it is not holding other items than the ListView; hence making the ListView the sole child of the ContentPage which is valid.
I would like to create a page like this: [1]: https://imgur.com/YreKQi3. But picker comes with underline and i also am not being able to display table separator line.
I tried to use tableview inside a frame but it didnt work. because frame's width is larger than table and seperator becomes invisible.

The code gives this output
But I want a page like this
The page difference is marked by blue ink.
This article by Alex Dunn looks like what you want exactly:
https://alexdunn.org/2018/06/06/xamarin-tip-dynamic-elevation-frames/
Note that you can control the Elevation as much as you want
You can use the HasShadow="True" atribute on Frame definition.
Where did you place the HasShadow? It need to be like this
<i> <Frame HasShadow="True" ...> </Frame> </i>

Can you please tell me how to stop the keyboard to hide the text box that is <Entry x:Name="txtentry" in above XAML.
It's quite a typical problem on iOS and there's a ready nuget plugin which you just need to import to your app and initialize. It will check whether the keyboard is not hiding the edited textbox and move the whole page up if it's needed.
