Lint the Code Base - Top Priority

[palisadoes]

We were having a large number of issues with code conflicts due to unlinted code. We have now added automated linting to the PR process, but will need to lint the entire codebase to this new standard.

Linting will include following the steps in the automation script shown here. Specifically:

1. Run Dart Analyzer on the codebase
2. Fix all Dart Analyzer issues. This must be completed before proceeding to the next step.
3. Run the flutter format command on the code base
   1. flutter format --set-exit-if-changed .

Coordinate with @DeltaHarbinger and @Sagar2366 on this issue.

We will reopen PRs when this issue is resolved. We are looking for someone to work on this quickly.

@Neha62-lit Would Pedantic create a differences in the output when compared to the approach we are using?
