Dynamic ViewModelLookup

Ability to add to Dictionary<Type, Type> ViewModelLookup in multiple places
https://github.com/matt-goldman/Maui.Plugins.PageResolver/blob/ff594dae8a38a20d365ca9748214a17df90aa052/src/Maui.Plugins.PageResolver/Resolver.cs#L13C5-L13C77

My Use case: We have an app with 100s possibly even a thousand pages, so to manage all the registration and configs, each area/ routes of the app has there own app builder to manage their section, f.e.

Currently in order to add the manual mappings they all need to be initialised at the same time, but in order to keep the code as maintainable as possible i'd like to keep the mapping next to the registrations.

Describe the solution you'd like
I see 3 possible solutions using the current code -

• Make InitialiseViewModelLookup public and remove ViewModelLookup.Clear(); (

  Maui.Plugins.PageResolver/src/Maui.Plugins.PageResolver/Resolver.cs

  Line 31 in ff594da

  internal static void InitialiseViewModelLookup(Dictionary<Type, Type> ViewModelMappings)

  )
• Make Dictionary<Type, Type> ViewModelLookup public so we can manage it ourselves if we'd like (https://github.com/matt-goldman/Maui.Plugins.PageResolver/blob/ff594dae8a38a20d365ca9748214a17df90aa052/src/Maui.Plugins.PageResolver/Resolver.cs#L13C5-L13C77)
• Create a new public method specific to adding to the dictionary

[IeuanWalker]

For now, I've added 2 new public methods to Resolver -

public static void AddViewModelLookup<T1, T2>()
{
    ViewModelLookup.Add(typeof(T1), typeof(T2));
}
public static void AddViewModelLookup(Dictionary<Type, Type> ViewModelMappings)
{
    foreach (var mapping in ViewModelMappings)
    {
        ViewModelLookup.Add(mapping.Key, mapping.Value);
    }
}

So now I can keep the mappings next to each of the registrations and in different files -

static class AppBuilderExtensions
{
	public static MauiAppBuilder RegisterWasteCalendar(this MauiAppBuilder builder)
	{
		builder.Services.AddTransient<AddressSearchPage>();
		builder.Services.AddTransient<AddressSearchViewModel>();

		builder.Services.AddTransient<DisplayPage>();
		builder.Services.AddTransient<DisplayViewModel>();
		Resolver.AddViewModelLookup<DisplayPage, DisplayViewModel>();

		builder.Services.AddTransient<RemindersPage>();
		builder.Services.AddTransient<RemindersViewModel>();
		Resolver.AddViewModelLookup<RemindersPage, RemindersViewModel>();

		builder.Services.AddTransient<AddPopup>();
		builder.Services.AddTransient<AddReminderViewModel>();
		Resolver.AddViewModelLookup<AddPopup, AddReminderViewModel>();

		builder.Services.AddTransient<EditPopup>();
		builder.Services.AddTransient<EditReminderViewModel>();
		Resolver.AddViewModelLookup<EditPopup, EditReminderViewModel>();

		return builder;
	}
}
