Cannot access a disposed object.\nObject name: 'PrimaryToolbarItem' - xamarin.forms

Question

I created a ToolbaItems in a ContentPage that is a ShellContent from FlyoutItem - I am using ShellApp.
<ContentPage.ToolbarItems>
<ToolbarItem
x:Name="xicon"
Clicked=""
IconImageSource="{local1:ImageResource MobileApp.Resources.Images.x.png}"
Text="Saw X" />
<ToolbarItem
x:Name="yicon"
Clicked=""
IconImageSource="{local1:ImageResource MobileApp.Resources.Images.y.png}"
Text="Saw Y" />
<ToolbarItem
x:Name="zicon"
Clicked=""
IconImageSource="{local1:ImageResource MobileApp.Resources.Images.z.png}"
Text="Saw Z" />
</ContentPage.ToolbarItems>
In Android it works well, but in iOS I got an error:
Message "Cannot access a disposed object.\n
Object name: 'PrimaryToolbarItem'." string
$exception {System.ObjectDisposedException: Cannot access a disposed object.
Object name: 'PrimaryToolbarItem'.

If I remove theses items in the constructor of the ContentPage it does not crash, I tried to use only Text, in Android I am using icon and works...
public HomePage()
{
InitializeComponent();
if (DeviceInfo.Platform == DevicePlatform.iOS)
{
this.ToolbarItems.Clear();
}
}
Is this a bug? In github I saw few issue about toolbar.

Yes, it is just the case. It is a known issue, and xamarin development team have added this to To do in xamarin form v5.0.1.
You can follow it up here:https://github.com/xamarin/Xamarin.Forms/issues/6387.
We are sorry for the inconvenience.And thanks for your support for xamarin.
