Widgetbook

Attending Fluttercon is a must for every Flutter developer!💙

Loved connecting with so many @widgetbook.bsky.social users again. These moments always feel very rewarding!💙

We had a booth, I gave a talk, hosted a roundtable with @abausg.bsky.social AND we of course organized the afterparty again🎉

Google featured Widgetbook as Flutter Package of the week!🎉

With 230k downloads, @widgetbook.bsky.social is helping developers around the world to build, test, and catalog their widgets in isolation.

Thanks a lot to our contributors and users for your support!💙
