While working with Rikulo is as straight forward as working with any other packages of Dart, to make this work in devices, one has to keep following things in mind.
First of all “Rikulo” itself is not capable of doing device level development, rather it depends upon “phonegap” (now cordova) and to compile against this, there is another package named “Rikulo Gap“. So the basic pub setup looks as this.

dependencies:
  rikulo:
  rikulo_gap:

Once installed the development process is straight forward as Dart itself while taking advantage of the Cordova APIs.
Upon completion of the development process, jump into “Dart to Javascript” compiler and generate the javascript file for the project. Fortunately thats as simple as going to “Tools” menu and clicking “Generate Javascript” in the Dart Editor. One has to select the “.dart” file first, for which the javascript file has to be generated. Upon successful generation of the file, the generated file name would be something like “myProject.dart.js”.
Now you have to add this “js” file in your “html” file like the usual “script” tag. That means to deploy to Cordova, you have to add two script tags as below.

Once done, open up the Eclipse or which ever IDE you are using to develop the Cordova (phonegap) applications, copy the “.html” and “.js” file into the respective folders of the Cordova project.
Lastly, but most importantly, remove the version number from the cordova JS file (for example cordova-2.3.0.js to cordova.js).
Now we have a workable native application built with Dart, Rikulo and Cordova.

Happy Darting !
