Adjust Width of Master on MasterDetailPage

I am using the MasterDetailPage for the NavigationDrawer on Android. Implementing the functionality has gone perfectly, however the width is too large and i would like to adjust it.

I have tried to set the WidthRequest for the ListView CellTemplate, ListView, and the Master Property of the MasterDetailPage all to the same value, and i can see that the cells are at the right width but the slide out part is still too big.

public MainPage(Action loginFaliedCallback) { MenuPage menu = new MenuPage { Title = "Menu", WidthRequest = 250 }; menu.Menu.ItemSelected += (s, e) => NavigateTo(e.SelectedItem as MenuItem); Master = menu; Master.WidthRequest = 250; }
Any information would be greatly appreciated. Thanks in advance.
