macOS Catalina Support

With the release of macOS Catalina just around the corner, we’ve made sure that our tooling continues to work smoothly as you migrate to Catalina, iOS 13 and Xcode 11. I should note that you’ll want to upgrade to the Flutter 1.9.1 stable release before upgrading to Catalina. The other order works, too, but you’ll see an error when you do it that way (the error is benign, but still…).
