Move flutter_lints to dev_dependencies

[jacksoncurrie]

Due to the flutter_lints package being in the dependencies many people will get version conflicts.

flutter_lints is only used in development so doesn't need to be shipped with this package. This will solve conflicts for all versions going forward and can be updated internally at any stage to fit project needs.

Moving to dev_dependencies: is also recommended by the flutter team when using flutter_lints as seen here.

This works until 3.0.2. 3.0.3 is blocked on flutter_lints ^2.0.1

Because XXX depends on geoflutterfire ^3.0.3 which depends on flutter_lints ^1.0.0, flutter_lints ^1.0.0 is required.
So, because XXX depends on flutter_lints ^2.0.1, version solving failed.

But if we move it to dev_dependencies geoflutterfire will not depend on flutter_lints at all when used in projects.

Same Issue Again So, because xx depends on flutter_lints ^2.0.1, version solving failed.

You'll want to see what depends on flutter_lints: ^2.0.1. This should always be in dev_dependencies, and only in your app. Any other dependencies should remove this from their dependency list.

I noticed that this is also fixed in PR #197, so if that gets merged, this can be dismissed.
