Shell Navigation with Models

[ziomek64]

Was this ever added? I remember long time ago there was a plan to add this in Xamarin.Forms but was moved to MAUI? - xamarin/Xamarin.Forms#6848

Is this a thing now or still not? That was my major no-go with shell. Other than that it was really simple to learn in small apps. Can't find anything btw.

Yes, this is possible. You can pass a Dictionary<string, object> parameter now.

object para1 = new();
Dictionary<string, object> parameters = new() { { "para1", para1 } };

await Shell.Current.GoToAsync("YOUR_URI", parameters: parameters, animate: true);

In the ViewModel, you can access the parameter like:

[QueryProperty(nameof(Parameter), "para1")]
    public partial class AppViewModel : BaseViewModel
    {
        #region QueryParameter
        [ObservableProperty]
        protected object parameter;
         //....
     }

The parameter can be any class type, for this example it`s just an object.

So finally any type of custom made object will work? That's the only issue I had working with out of the box xamarin. That's amazing

[AndreasReitberger]

Yes, you can pass any custom object with the example above ;)

Great, can't wait to implement it
