BREAKING CHANGE: library.yaml was renmed to strict.yaml, and ...

Removed the following lint rules:

• avoid_types_on_closure_parameters: Too many false positives.
• cascade_invocations: Too prescriptive, separate lines can be useful for readability.
• cast_nullable_to_non_nullable: Could be useful as a code review hint, but too verbose for a lint.
• one_member_abstracts: Avoiding unnecessary classes is good design guidance, but not as a lint.

Added the following lints:

• comment_references: Enforces that all references in comments are valid. There are some false positives between this and what dartdoc supports, but it's probably worth ignoring those versus not knowing if a reference is valid.
• missing_code_block_language_in_doc_comment: Useful for ensuring that code blocks are syntax highlighted.
• unnecessary_library_name: There are no benefits to having a library name in modern Dart.

BREAKING CHANGE: application.yaml was renamed to relaxed.yaml, and ...

Removed the following lints:

• avoid_redundant_argument_values: Causes a lot of churn for little benefit.
• unnecessary_raw_strings: Too prescriptive, raw strings can be useful for readability.

In addition, updated package:lints to ^4.0.0 (was ^3.0.0).

Added a new set, package:oath/flutter/*.yaml, for Flutter packages.

# analysis_options.yaml

# Strict set of lints and analysis options.
include: package:oath/flutter/library.yaml

# Relaxed set of lints and analysis options.
include: package:oath/flutter/application.yaml

Initial release, with two sets of lints:

# analysis_options.yaml

# Strict set of lints and analysis options.
include: package:oath/library.yaml

Or, for a slightly relaxed set for applications:

# Relaxed set of lints and analysis options.
include: package:oath/application.yaml
