Felix Angelov, whose bloc package is one of the mainstays of state management in flutter, has just released version 5. If you're using flutter_bloc in your code, as I am, you've probably already seen the upgrade prompt, but if you'd like to learn the details, Felix's migration guide should help you get started on bringing your code in line with version 5.
As if Felix hasn't been busy enough with the Bloc upgrade to version 5, he's also been working on a more lightweight version of Bloc, called Cubit, and his approach here seems promising for many use cases.
Although Cubit had been released initially as its own package, Felix received enough positive feedback on combining it with Bloc that it's now the official direction. The link in the title gives you the details on the code merge, which now appears to be slated for Bloc version 6. (And yes, this will likely bring breaking changes to Bloc, so be prepared.)
Sometimes it's easy to miss some of the standard Flutter Widgets which are available. I have to confess that AboutDialog was one of those for me, as I didn't discover it until after I had already implemented my own. :-(
One of the most useful features of AboutDialog is its "View Licenses" button, which will automatically show the licenses used by your application, and which can be extended to show additional licenses if they aren't picked up automatically for you by the underlying LicenseRegistry API.
