An out-of-the-box solution for handling lo- and hi-resolution images across devices with different resolutions, aspect ratios, and network connections. For example: https://github.com/adamdbradley/foresight.js

A solution is not trivial. A dart library would help, but may need to be coupled with a service similar to http://www.imgix.com/ and/or eclipse tooling to manage, package, and deploy image assets.
