A simple example mod showing the main feature of flux. This is restricted to fabric loader methods but runs on Quilt near perfectly.
In order to run this example mod you need to look at the gradle tasks. In the tasks you should see a folder named runs, click on it. After that you can see the runFabric and runQuilt buttons. Click on any of those tasks and you will run your mod.
To share your mod look at the folder named shadow in gradle tasks. Open that folder and click shadowJar and that will build and export it.
To find your exported build look in the build/libs folder in your file tree/explorer.
If you want to customize your mods or update dependencies you can mess with that in the file gradle.properties.
Also to change your mod name look in the settings.gradle file.
