We desperately need a "monthly downloads" kind of metric on pub to actually judge how much a package is being used, and not just how many likes it managed to get over the time.
Also important to be informed about what you use.
- GetX hasn't published a new version in 6 months. And before that one update, it was quiet for a long time.
- Almost 900 issues on the repo with very little activity addressing them
- 1 PR merged in the past 5 months
It can definitely come back, but as of now it's looking more like an abandoned project
