flutter Flutter for MacOS My first case study for building apps for MacOS was to use Apple's built-in capability of running iOS apps natively on Macs with Apple Silicon (see https://www.wafrat.com/flutter-ios-app-for-macos/).

github Adding the `Update branch` to GitHub PRs In my repositories, my PRs didn't have the Update branch button.
