Would be good to have example how to use FadeInImage

[FastNinja]

just at the moment trying to read source code of flutter to figure out what is the exact usage...
once I figure it out - will update the issue.

The doc of FadeInImage is pretty easy and straightforward.

return new FadeInImage(
  // here `bytes` is a Uint8List containing the bytes for the in-memory image
  placeholder: new MemoryImage(bytes),
  image: new NetworkImage('https://backend.example.com/image.png'),
);

Just use CachedNetworkImageProvider for 'image' and for example an assetimage for 'placeholder'.

Probably going to remove it from the readme in the next version. It is also mentioned in the changelog.

@renefloor this is the working example. Notice the AssertImage usage - as usually your placeholder is some static image..

 child: new FadeInImage(
                            
                            placeholder:
                                new AssetImage("images/placeholder.png"),
                            image: new CachedNetworkImageProvider(imageUrl),
                          ))))

by the way - all worked with new version. Awesome work @renefloor !

Yes indeed, an AssetImage would be a good choice, or the MemoryImage in my example. A MemoryImage shows even faster (so no flicker), but you have to load it yourself first.

@FastNinja because I also wanted some way to show an error I started working on a widget that holds a placeholder and an error widget. Would like to hear your opinion on it. It is still a work in progress, but I already published an alpha.
