ShowToast return instance

[Cvijo]

@chrissainty this is the first draft of this feature.
I have fixed some bugs with custom toasts (they did now follow MaxToastCount rule and queue logic)
In code I have put my comments for some changes and will remove them when we agree on them, they all start with //todo remove comment after review
`

I am not sure about toastInstance.Dispose(), can you check if that is fine with you, if yes i will have to implement those on ClearAll methods too.

Here is screen shoot.

@chrissainty I am not sure how to adjust unit testing (I never wrote any) on these new events that now return an instance. Do you know anyone who could help with that?
I have tried something but i don't think it is the correct way, created a mock Instance and returned it.

    internal class MockToastInstance : IToastInstance
    {
        public Guid Id => Guid.NewGuid();

        
        public void Close() {}
    }


    [Fact]
    public void OnShowInvoked_When_ShowWarningCalled()
    {
        // arrange
        var instance = new MockToastInstance(); 
        var onShowCalled = false;
        
        _sut.OnShow += (_, _, _) => { onShowCalled = true; return instance;  };
        // act
        _sut.ShowWarning("message");

        // assert
        Assert.True(onShowCalled);
    }

I wouldn't mock anything. I'd render a real toast instance verify its there then call close on the instance and verify it's now gone. That way the test will be testing real stuff and no mocks

As i said i never do any kind of unit testing, now it fails because OnShow and every other event returns instance instead of void and i don't know how to change them

_sut.OnShow += (_, _, _) => onShowCalled = true;

OnShow has to return instance and to my zero knowledge on unit testing i could only make it work with code i posted.
If you can share one sample of this test how should i change it i could do the rest

    [Fact]
    public void OnShowInvoked_When_ShowSuccessCalled()

And btw. I wanted you to check if this is even an option for this feature to return ToastInstance

[chrissainty]

No worries. I might be able to get a bit of time this evening to get on the laptop. I'll do my best to write up an example.

@Cvijo Sorry I've not been able to help with this for so long. I think the mock instance will do for now. I can rework the tests once we merge things if there are any major issues.
