Crashing on back in ios and doesn't update in android

[amrkamal1993]

It works fine but if you are on a navigation page with zero items go forward and then go back it get crash on iOS. On android the number doesn't update when you go back . At least on my MVVM project.

On Android, I was also facing the same issue: "the badge value was disappearing for example while going back (or pressing the back button).

However, I've fixed the issue by applying the following workaround,

Task.Run(async () =>
                {
                    await Task.Delay(500);

                    //Call the method which should update the badge value here
                });

So, while debugging, I noticed all code and everything looked fine, and most likely the events were not being executed in the right order. However, adding little delay actually fixed it.

You have to insert in your App.xaml.cs this following code:

public App()
{
        .......
 	navigationPage.Popped += NavigationPage_Popped;
        ........
}

private void NavigationPage_Popped(object sender, NavigationEventArgs e)
{
	if (ToolbarItems.Count() > 0)
	{
		DependencyService.Get<IToolbarItemBadgeService>().SetBadge(e.Page, ToolbarItems.First(), $"{CartNumber}", Color.Red, Color.White);
	}
		
}

It worked perfectly but there is a slight fluctuation to load the badge, anyhow thanks for the help and btw do you have any idea why this is happening and any other way to fix it?

Not sure why is this happening, but most likely it's a bug in the library. Alternatively, you may also try the approach suggested by "Gasdani" above as that may also fix it. Thanks!

I don't know your code but i doing in this way:

var menuPage = new MasterPage(); 
NavigationPage navigationPage;
navigationPage = new NavigationPage(new PageHome());
navigationPage.Popped += NavigationPage_Popped;
var rootPage = new RootPage(); //This is my MasterDetailPage
rootPage.Master = menuPage;
rootPage.Detail = navigationPage;
