dart_scorm

A small Dart package that lets a Flutter or Dart web application talk to the LMS that launched it. ScormAPI.findApi() walks the window hierarchy and then the opener hierarchy looking for an API object — preferring SCORM 2004's API_1484_11 and falling back to 1.2's API — after which initialize, getValue, setValue, commit, finish and terminate pass calls straight through to JavaScript.

That is the whole surface, and for the problem it addresses that is the right size. Flutter web output is a canvas inside an iframe; finding the API adapter across frames is fiddly, and this package removes the fiddliness in a few lines. The example project is genuinely useful — it shows the iframe wrapper, the manifest and the zip layout that make a Flutter build launchable as a SCO.

What it will not do: validate anything. There is no CMI data model, no type or vocabulary checking, no packaging step, and no help with completion or scoring semantics — write the wrong element and the LMS, not the library, tells you.

For someone deciding today: this is a single-maintainer package with a handful of stars, last released in August 2023 to add Dart 3 and null safety, and untouched since. Because it is a thin binding over an API that has not changed since 2009, staleness costs less here than it would in a runtime. The real risk is Flutter's own web renderer moving underneath it, not SCORM.
