A ReactiveUI view model based navigation library

Sextant was born from a fork of Xamvvm which is nice and simple MVVM Framework with a good navigation system. The problem is, I just wanted a simple navigation system to use with ReactiveUI without all the things that come along an MVVM framework. Plus, I wanted to make it more "Reactive Friendly".

Then a wild Rodney Littles appears, and with him an implementation of this AMAZING POST by Kent

Sextant is in a very initial stage and in constant change, so please be pantience with use... because we will break things.

This library is nothing more than me "standing on the shoulders of giants": Kent for been the original and true creator of this, I pretty much just copied and pasted it 😃 Geoffrey Huntley maintainer on ReactiveUI.

Target Platform Versions

Verify you have the minimum version for your target platform (i.e. Android, iOS, Tizen).

Register Components

Views

Version 2.0 added new extensions methods for the IMutableDepedencyResolver that allow you to register an IViewFor to a View Model.

Locator
    .CurrentMutable
    .RegisterNavigationView(() => new NavigationView(RxApp.MainThreadScheduler, RxApp.TaskpoolScheduler, ViewLocator.Current))
    .RegisterParameterViewStackService()
    .RegisterViewForNavigation(() => new PassPage(), () => new PassViewModel())
    .RegisterViewForNavigation(() => new ReceivedPage(), () => new ReceivedViewModel());

Set the initial page:

Locator
    .Current
    .GetService<IParameterViewStackService>()
    .PushPage<PassViewModel>()
    .Subscribe();

MainPage = Locator.Current.GetNavigationView("NavigationView");

Use the Navigation Service

After that all you have to do is call one of the methods inside your ViewModels:

/// <summary>
/// Pops the <see cref="IPageViewModel"/> off the stack.
/// </summary>
/// <param name="animate">if set to <c>true</c> [animate].</param>
/// <returns></returns>
IObservable<Unit> PopModal(bool animate = true);

/// <summary>
/// Pops the <see cref="IPageViewModel"/> off the stack.
/// </summary>
/// <param name="animate">if set to <c>true</c> [animate].</param>
/// <returns></returns>
IObservable<Unit> PopPage(bool animate = true);

/// <summary>
/// Pushes the <see cref="IPageViewModel"/> onto the stack.
/// </summary>
/// <param name="modal">The modal.</param>
/// <param name="contract">The contract.</param>
/// <returns></returns>
IObservable<Unit> PushModal(IPageViewModel modal, string contract = null);

/// <summary>
/// Pushes the <see cref="IPageViewModel"/> onto the stack.
/// </summary>
/// <param name="page">The page.</param>
/// <param name="contract">The contract.</param>
/// <param name="resetStack">if set to <c>true</c> [reset stack].</param>
/// <param name="animate">if set to <c>true</c> [animate].</param>
/// <returns></returns>
IObservable<Unit> PushPage(IPageViewModel page, string contract = null, bool resetStack = false, bool animate = true);

Example

public class ViewModel
{
    private readonly IViewStackServicen _viewStackService; // or IParameterViewStackServicen

    public ViewModel(IViewStackServicen viewStackService)
    {
        _viewStackService = viewStackService;

        OpenModal = ReactiveCommand
            // FirstModalViewModel must implement IViewModel or INavigable
            .CreateFromObservable(() => viewStackService.PushModal<FirstModalViewModel>(),
                outputScheduler: RxApp.MainThreadScheduler);
    }

    public ReactiveCommand<Unit, Unit> OpenModal { get; }
}

Pass Parameters

Version 2.0 added support for passing parameters when navigating.

Example

public class ViewModel
{
    private readonly IParameterViewStackServicen _viewStackService;

    public ViewModel(IParameterViewStackServicen viewStackService)
    {
        _viewStackService = viewStackService;

        Navigate = ReactiveCommand
            // NavigableViewModel must implement INavigable
            .CreateFromObservable(() => viewStackService.PushModal<NavigableViewModel>(new NavigationParameter { { "parameter", parameter } }),
                outputScheduler: RxApp.MainThreadScheduler);
    }

    public ReactiveCommand<Unit, Unit> Navigate { get; }
}

The INavigable interface exposes view model lifecycle methods that can be subscribed to. These methods unbox your parameter object. Implementing the interface allows you to assign values to the View Model during Navigation.

public class NavigableViewModel : INavigable
{
        public string? _parameter;

        public IObservable<Unit> WhenNavigatedFrom(INavigationParameter parameter)
        {
            return Observable.Return(Unit.Default)
        }

        public IObservable<Unit> WhenNavigatedTo(INavigationParameter parameter)
        {
            parameter.TryGetValue("parameter", out _parameter);
            return Observable.Return(Unit.Default);
        }

        public IObservable<Unit> WhenNavigatingTo(INavigationParameter parameter)
        {
            return Observable.Return(Unit.Default);
        }
}
