I want to create an Android App with Xamarin.Forms.
I create an Object on the Mainpage. This object is a Collection of many other Objects.
My goal is to push this Collection-Object to another Page, and on this Page i want to add an Object to the Collection-Object. After this i want that the newly added Object is in the Collection on the MainPage.
I am Navigating between Pages with Push and Pop.
The YT Tutorials only work in one direction, so that i can see the object on the second page, but when i add an Object to the Collection, it isn't visible on the second Page.
