Add Generic Lifecycle Events #8780

Open dansiegel opened 2 years ago

dansiegel commented 2 years ago

Description

The Application exposes methods to handle OnStart, OnSleep, & OnResume. It is technically possible to hook into these events if multi-targeting and providing native delegates for these Lifecycle Events. Since we already accept that these are platform agnostic events these should exist on the cross platform API for the LifecycleEvents builder.

Public API Changes

This should be generally available on the net6.0 API so that it can be done generically to support any target without the need to explicitly provide a target for an individual platform.

builder.ConfigureLifecycleEvents(lifecycle =>
{
    lifecycle.OnStart(() => {
        // My handler
    });
    lifecycle.OnSleep(() => {
        // My handler
    });
    lifecycle.OnResume(() => {
        // My handler
    });
});

Intended Use-Case

Provide handlers cross platform without the need for libraries like Prism to explicitly provide a compiled target for Android, iOS, Mac, Windows, Tizen, etc.
