Flutter: A project with the name android already exists. Duplicate root element android

Question

I currently have a Flutter app that gives an error in VSCode; the project itself builds for Android without issue. The issue appears to plague solely the VSCode editor and is down to there being a sub-project within the main project for Android. This is because I've nested (copy & pasted) a custom flutter package into the local file structure, and the local flutter package includes an example project.

Ideally I'd like to not delete the "example" directory from the nested local package, I'd like VSCode to just relax. Is there a way to deactivate these warnings?

Update: By recreating the package using the plugin commands, as suggested below, the root issue still remains though the error text has changed slightly to be as shown below:

The supplied phased action failed with an exception.
A problem occurred evaluating settings 'android'.
A problem occurred evaluating script.
assert pluginDirectory.exists()
       |               |
       |               false

Try disabling the VS Code extension "Language Support for Java(TM) by Red Hat" if you have installed it. I had the same issue and disabling that extension solved it.
