I have been working minimally with CI/CD for a couple years now, configuring projects to perform builds and deploy artifacts to desired platforms.
However, I recently went up another knoch in the DevOps knowledge stack.

Fireship’s explanation of DevOps CI/CD.
Codemagic is a popular CI/CD platform that I personally use for all of my Flutter projects.
Prior to, I would have to manually come into the dashboard and start the builds for an app, but I have now learned about automatic build triggering.
By specifying a branch (or branches) to watch, I can tell Codemagic to create a new build whenever changes are pushed to said branch.

Demonstration of automatic build triggering when I push to the main branch.
This is very helpful whenever I make improvements to an app, and finally merge my changes into the main branch.
I can now sit back and wait for the new version of the app to be published to the App Store and Play Store.
