Hello and welcome to another stable release of Flutter. So far this year, we’ve been right on target with one stable release each quarter, as per our plan (well, less of a plan and more of a goal, but still, it’s been working out pretty well so far…). This release is our biggest yet, with 1,548 Pull Requests merged from 108 contributors. As always, the interesting PRs are listed below. And there are lots of interesting things to discuss in this release, including:

One regression fixed but also one added
Some breaking API changes
Some severe issues caught and fixed
Support for macOS Catalina and iOS 13
A number of new features
And more!
And to be clear, when I say “we,” I mean the Flutter community as a whole. The Flutter team couldn’t possibly continue to scale as we have without all of our contributors, no matter who your employer is. Thanks everyone for your contributions!
