Use case

Rather than excluding a certain file from analysis for the entire project, We can enable the devs to exclude certain file from analysis only for a single instance of flutter analyze.

Ran into this trouble where I wanted to exclude one file from analyze when done via github actions, as certain firebase_config files aren't in the repo, but kept locally.

Proposal

Create a new flag --exclude <relative file location> for flutter analyze to exclude this file for this specific flutter analyze run
