Xamarin TabbedPage Performance When Using Children.Add - xamarin

Question

Good Afternoon,
I have a question regarding the performance of the tabbed page and whether there is a more efficient way to load the tabs into the page, without any frame loss or process hang.
Regarding this issue, I have been having a few issues with TabbedPage in Xamarin.Forms. My project currently consists of a Listview with 104 components. When I click on one of the items it opens up a tabbed page consisting of 3 tabed pages. I start the tabbed page using the following code
int Clicked = 0;
public async Task CheckClick(Page data)
{
Clicked += 1;
if (Clicked == 1)
{
await Navigation.PushAsync(data);
List_View.SelectedItem = null;
}
}
public async void OnSelection(object sender, SelectedItemChangedEventArgs e)
{
if (e.SelectedItem == null)
{
return;
}
var Cell = e.SelectedItem as DataSource;
switch (Cell.ID)
{
case 0:
await CheckClick(new Function_One());
break;
}
}
The real problem comes after, whether I pre load the information ahead of time or do what ever, whenever I call Children.Add(data); the whole application hangs for 1 or 2 seconds and than allows the page to load. The code is as follows.
public class Function_One : TabbedPage
{
private async Task Test()
{
//
var data = new NewPageData("", "", "OP.png", "Persian.png", Description, Usage, Storage, Data);
var data2 = new NewMedicalPage(Medical_Info, Translation, startinfo);
var data3 = new NewNotePage("", 0);
data.Icon = "Info.png";
await Task.Delay(100);// Little await to load the page first before hang
Device.BeginInvokeOnMainThread(async () =
{
Children.Add(data);// HERE is the freeze
Children.Add(data2);// these
Children.Add(data3);// 3 (Adding of the Tabs)
});
}
public void UpdateData()
{
Task.Run(async () =
{
try
{
Description.Spans.Add(new Span
{
Text = "Data.... ",
FontSize = 18,
FontFamily = variables.fontFamily
});
Usage.Spans.Add(new Span
{
Text = "MoreData...",
FontSize = 18,
FontFamily = variables.fontFamily
});
Storage.Spans.Add(new Span
{
Text = "LastData...",
FontSize = 18,
FontFamily = variables.fontFamily
});
await Test();
}
catch { }
}).ConfigureAwait(false);
}
public Function_One()
{
UpdateData();
BarBackgroundColor = MainColor;
BarTextColor = Color.WhiteSmoke;
Title = "Page";
}
}

If anyone could explain to me a better method for loading the data while keeping the application flowing and smooth, that would be appreciated. The data does not have to load all at once, just as long as the page opens as soon as its clicked!
