Question: can you inject NavigationService into the BaseViewModel

[dhaligas]

Is there a way to always have the BaseViewModel inject the NavigationService?

I would like to wrap the functions esp to have a single place to handle double tapping / modals etc

[brianlagunas]

What BaseViewModel? Prism doesn't have a BaseViewModel. What platform are you using?

[dhaligas]

I am using

BaseViewModel : BindableBase, INavigationAware

I want to know if I can inject services into my BaseViewModel that every ViewModel inherits

I guess I could write an extension to the navigation service to handle the double tap

[brianlagunas]

You can, but you have to also inject them into your derived class and pass them to your base ctor.

Why would you modify the NavigationSevice to handle a double tap? That should be handled by your UI, and you would call a navigation action on the double tap.

What platform?

I am handling the case where the command is invoked faster than it can complete the first tap.

I have had issues in apps with the tap gesture and the ability to tap it fast and get multiple pages pushed to the stack

What platform?

[dhaligas]

mostly on android but sometimes on iOS

[brianlagunas]

Okay, so you are using Xamarin.Forms. Once again, this is not something you will handle in the navigation service. The TabGestureRecognizer has a property that lets you define a double tab called NumberOfTapsRequired. If you want to prevent a double tap, then you need to handle this logic in your ViewModel, not the navigation service.
