Lint rules suggestion.

Quality improvement Suggestion

There are a few technical issues which could be prevented by lints.
In the same way, Lints could enlighten syntax improvements.

The rules I have in mind to prevent issues :

• unawaited futures
• BuildContexts used across asynchronous gaps
• switch statements missing cases

The ones to improve syntax :

• Use named constants instead
• Fix code references in comments
• Throw error subclasses only
