lint_hard

• removed the older conflicting lint async_return_with_no_await. Dart now recommends the newer async_return_with_no_await for cleaner stack traces.

• require Dart 3.13 or later.
• add the lint rules introduced in Dart 3.11, 3.12, and 3.13.

• removed the lint simplify_variable_pattern as it isn't available until 3.11

• split the document_throws code into its own package and now depend on that.
• numerous fixes to document_throws.

• added the throwing_unthrown_exception lint for @Throwing types that are not thrown.
• improved document_throws_fix handling for provenance cleanup and doc comment formatting.
• clarified plugin configuration and documentation.

• re-ordered the readme so that the install instructions are closer to the top.

• implemented new lint: document_thrown_exceptions that warns when a method has not documented a throws clause.
• migrated the code away from custom_lint to the analyzer v9 package.
• UPGRADE: if upgrading from lint_hard 6.x you will need to include a plugin declaration in your analysis_options.yaml file to activate the custom lints in lint_hard. See the README.md for details.

• disabled type_annotate_public_apis as it is incompatible wiht omit_obvious_property_types which I consider the more important lint for most users. If you are a package maintainer you should re-enable type_annotate_public_apis for your public api's.

• added custom lint 'fields_first_constructors_next' which places fields before constructors so that the state of a class is at the top and together.

• removed unsafe_variance. It's experimental and the suggested fixes seem overly complicated and you still have to suppress the warning.

Added new lints:

• omit_obvious_property_types
• deprecated_member_use_from_same_package
• unsafe_variance

• added 3.7 lints

• added new 3.0, 3.1 lints from the linter project

• removed prefer_foreach because I prefer a for loop.
• upgraded to dart 3.0

moved to stable 2.19

• removed strong mode as it is deprecaed in favour of the new
• removed implict-casts as its no longer required and has been removed in 3.x

• disabled no_leading_underscores_for_local_identifiers as its useful in callbacks that have a parameter we don't want to use.

• added latest lints from dart 2.19 and upgraded minimum sdk version to 2.19.

• improved the readme.
• removed invariant_booleans as it has been deprecated.

• Added additional lints for upcomming 2.18 and 2.19 releases.
