About This Article
Flutter had a growing backlog of unresolved issues that hurt quality. The team needed to rebuild their infrastructure and create a sustainable release process that could deliver hotfixes to the stable branch regularly.
Chris Sells' team worked with Nevercode to respond faster to customer issues. They merged 3,164 pull requests from 231 contributors and built a new release model that prioritized quality.
Since version 1.12, Flutter closed 6,339 issues. The number of open issues dropped by about 800, and for the first time in 2020, they closed more bugs than they opened.
