The nodata.png is not centered on the screen - fix

[judismith]

In the video at 3:43:45 the image on nodata.png is displayed as being centered on the screen. The code demonstrated does not result in a centered image. Additionally, the code in the Read Me also does not result in the image being centered. However, the following code does work:

<CollectionView.EmptyView> <Grid HorizontalOptions="Fill" VerticalOptions="Fill"> <Image Source="nodata.png" HeightRequest="160" WidthRequest="160" Aspect="AspectFill"> </Image> </Grid> </CollectionView.EmptyView>

Yeah, I think i made adjustments to it as I was able to get it centered on some operating systems and not on others.
