How to show Menu in MasterDetail Page when using Prism and Custom Title bar

Question

I am completely new to Xamarin.

I am working on a project where Prism framework is used for navigation (my first xamarin project) The requirement needed a custom title

Answer 1

Just have a boolean property in your Master page's ViewModel, let's call it IsMenuPresented, then in your MasterPage XAML:

If you want to be able to toggle the menu from code, you can either:

1) do something like

(App.Current.MainPage is MasterDetailPage mainPage).IsPresented = true;

2) Use Prism's Event Aggregator to subscribe to an event in the Master Page's ViewModel that will listen for a true/false value that gets published from some other ViewModel and set IsMenuPresented accordingly (thereby showing/hiding the menu).
