In short, the flutter_version() you saw is a Fastlane plugin I wrote to help manage Flutter versioning.

https://github.com/tianhaoz95/photochat/blob/9d1f3c5103c61daa64abe59aaa780afdf7b7dec1/photochatapp/android/fastlane/Fastfile#L8-L14

It's a bit confusing because the plugin doesn't live here. Instead, it in imported through a gem registry here:

https://github.com/tianhaoz95/photochat/blob/9d1f3c5103c61daa64abe59aaa780afdf7b7dec1/photochatapp/android/fastlane/Pluginfile#L1-L3

The plugin itself actually lives here: https://github.com/tianhaoz95/fastlane-plugin-flutter_version

As the plugin was built in a hurry, documentation is not fully in place now, but you can take this repository as an example.

The plugin uses GitHub registry: https://github.com/tianhaoz95/fastlane-plugin-flutter_version/packages/143774

Installing it will require logging in with your GitHub account, please take my GitHub Action script as an example:

Reusing this issue to add the documentation on how the Fastlane plugin works and how to set it up as the flutter_version plugin was a brother project of this one and also maintained by the same contributors.

BTW, the docs uses vuepress.
