Add hero animation support

[speshiou]

Describe the Feature

To improve the user experience, adding support for hero animation can be beneficial.
I'm not sure if this feature already exists. However, I couldn't find any reference to this capability in the docs.

Suggested Solution

To incorporate hero animations, the two widgets in the different routes should be extended to the Hero widget with the corresponding tag. This can be achieved by:

• Adding a tag property to the showImageViewer
• Wrapping the image viewer with a Hero widget if the tag is provided.

@speshiou Thank you for the suggestion. I'll take a look, but it will probably take a bit for me to get around to it. If you want to provide some sample code or even a PR: That would be great :)
