Jaspr just reached 2000 stars on Github. ⭐️ 🚀
Huge thanks to everyone for supporting Jaspr! 💙

me 10 years ago: I love Android, best OS ever.

me now: someone kill Gradle, Android Studio and Java dependencies for the good of humanity.

I discovered this in our templates repository. Now they all point to the latest version so we don't forget to update it, but you can always pin a specific version if needed.

It's documented, but I haven't seen many projects doing this, so I thought I'd share. ☺️

Are you upgrading Very Good Analysis correctly? 🤔

If you use Dependabot, it updates pubspec.yaml but not analysis_options.yaml if you pinned a version.

Use the latest version instead, then Dependabot PRs are all you need (aside from fixing warnings/errors). 👍
