Xamarin.FinalNav

Get your Xamarin.Forms Pages and ViewModels into the real DI world.

How to:

1. Create your container at your Platform
2. Register your platform Services
3. Hand the IoC container to your App
4. Register your shared Services
5. Register your Pages
6. Initialize the Navigation
7. Navigate like a Pro 😎

Note: All files and Lines here base on the Sample project

---

1 new Ioc container MainActivity.cs

var ioc = new FinalIoc();

---

2 Register platrform services MainActivity.cs

ioc.RegisterService<IPlatformDependentService, AndroidPlatformService>();

---

3 LoadApplication MainActivity.cs

LoadApplication(new App(ioc));

Note: "App.xaml.cs" needs the FinalIoc as constructor parameter

---

4 Register common code services App.xaml.cs

container.RegisterService<IDemoService, DefaultDemoService>();

---

5 Register pages App.xaml.cs

container.RegisterPage<LoginPage, LoginPageViewModel>();
container.RegisterPage<UserPage, UserPageViewModel>();

---

6 Build the Navigator App.xaml.cs

new FinalNavigator(this, container).Build<LoginPage>();

---

7 Navigate LoginPageViewModel.cs

To be able to Navigate include the "INavigationService" interface in the Page/ViewModel constructor:

public LoginPageViewModel(INavigationService navigationService)

Use the NavigationService to navigate further with all your services always on hand

await FinalNavigator.Instance.PushAsync<UserPage>(new NavigationParameter
{
    Type = EParameterType.ViewModel,
    Parameter = Username,
});

Note you also be able to use the following class constructors:

public PageParameter(object parameter)
public ViewModelParameter(object parameter)

NavigationMethods:

• PushAsync(params NavigationParameter[] userParameters)
