    # It does, however, make code safer when this cannot be done without involving
    # an extra local variable for clarity and safety. Enabling this error, even as just a warning,
    # does get in the way a bit if all you want to do is a null to default value release runtime
    # safety/fallback assignment. For that use case, you have to add a local rule override. With

    # "Assigning new values to parameters is generally a bad practice unless an operator
    # such as ??= is used. Otherwise, arbitrarily reassigning parameters is usually a mistake."

    # The linter rule link above states this rule is from the Flutter style guide.
    #
    # This makes most code intent very explicit, sometimes this may help you
    # reason about unfamiliar libs, but it might get tedious when dealing with very familiar ones.
    # For devs used to more relaxed or no type declaration, it is probably the other way around.

    # violates Effective Dart "AVOID type annotating initialized local variables".
    # https://dart.dev/tools/linter-rules/omit_local_variable_types.html
    # Which we find to be a strange rule, the package lint agrees with the statement that

    #
    # Turning always_specify_types lint rule on in a project at a later stage is very tedious,
    # fixing all the analyzer warnings will take quite some time. Having it on as you write new code
    # is not so bad though, the IDE will handle it most of the time.
    #
    # Most people probably want this lint rule OFF, but for now we keep it on in our projects.
    # We might reconsider this choice later. For example, this issue has requested
    # a new softer related lint rule that could be used only for declarations:
    # https://github.com/dart-lang/linter/issues/1620
    # If such a lint rule materializes, we might switch to using it instead and turn off this lint.
    #
    # Using always_specify_type ON lint like Flutter repo does, makes it easier to reason about
    # unfamiliar codebases, especially when you read it on GitHub where the IDE cannot be used to
    # look into what type an object is.

    # This rule conflicts with `prefer_relative_imports` so we turn it OFF.
    # We are still conflicted about which version to use, keeping it this way for now. Support
    # for relative imports has improved in both IDEs. Adding imports still often get imported as
    # package imports, and then you have to edit them manually. The IDEs can help with fixing them.
    # The relative paths can be a bit messy to keep track off, package imports are actually
    # a bit easier from that point of view.
    # Flutter repo now also prefers relative imports over package imports, so that is
    # another reason to use that.
    #
    # Use what you prefer, but you have to be consistent though, since mixing and matching can
    # cause issues as the same file imported with the different options are considered to be
    # different libs and code, even if it is the same file. This may impact the functionality
    # of e.g. singletons, service locators and increase code size.
    #
    # When you refactor and move folders with a lot of code in them, that other code depends
    # on for imports via relative imports, then they get messed up by Flutter IDEs
    # VS-Code and AS/IntelliJ. Both main Flutter IDEs may fail to correctly refactor moved folders
    # and imports that depend on files in the moved folders.

    # AVOID defining a class that contains only static members.
    #
    # https://dart.dev/tools/linter-rules/avoid_classes_with_only_static_members.html
    #
    # Creating classes with the sole purpose of providing utility, or otherwise static methods, is
    # discouraged in effective Dart. Dart allows functions to exist outside of classes for this
    # very reason. Effective Dart says avoid classes with only static members:
    # https://dart.dev/guides/language/effective-dart/design#avoid-defining-a-class-that-contains-only-static-members
    # However, the Flutter style guide says use them when it makes sense:
    # https://github.com/flutter/flutter/wiki/Style-guide-for-Flutter-repo#begin-global-constant-names-with-prefix-k
    # Colors is an example of such a class, but they still enable this rule in the repo though, go figure.
    #
    # Like Pedantic, we like util and static classes too, so we use them.
    # We tried the Effective Dart style and used kConstants in different const files. This
    # is more cumbersome to use than static classes. The import is simpler with static classes and
    # the code looks cleaner. If you use a lot of constant files, importing them is more tedious,
    # and you cannot enforce a given 'as' name to have a consistent name space prefix. A static
    # class gives you that automatically, thus providing context for the constants and static functions.

    # are OK when they are the ONLY boolean parameter in a callback, and also very handy when used in a

    #
    # Flutter API contains many callbacks with the signature: {void Function(bool) onChanged} often

    # PREFER asserts with a message string.
    #
    # https://dart.dev/tools/linter-rules/prefer_asserts_with_message.html
    #
    # When assertions fail, it's not always simple to understand why. Adding a message to the
    # assert function helps the developer to understand why the AssertionError occurs.
    #
    # While this is true, Dart does nowadays create very clear messages from assert-terms by default.
    # Flutter SDK does not use this rule or style. When you use code from it for customized
    # widgets, you will end up having to write your own messages for the code snippet.
    #
    # Rationale for not using this in Flutter SDK:
    # "Assertions blocks don't require a message because they throw simple to understand errors"
    #
    # We agree, so we do not mind turning OFF this rule when it becomes tedious, but we start
    # with it ON. With NNBD, you also usually need fewer asserts than you did before in Dart code,
    # since NNBD made almost all "not null" assertions unnecessary.

    # Dart has named constructors. Static methods in other languages (java) are a workaround to

    #
    # We don't mind this lint rule, it is OK, BUT we noticed that
    # if you want/need to create instances of classes via static helpers in another class, that
    # this lint rules complains about it. We are OK with preferring a named constructor over a
    # static method to create an instance from within the same class. However, this lint rule
    # complained about the above usage too, where we think it makes sense to use a static method.
    # This rule currently complains about use cases that in some scenarios are impossible to comply
    # with. Maybe this is another issue with this lint rule. We should investigate it further and
    # report it if it is an issue. For now, we disable this rule.

    #
    # All non-overriding public members should be documented with /// doc-style comments.
    # Not necessary for an app or the examples in a pub.dev package. I always enable this for
    # public packages.
    #
    # NOTE: There is also the lint rule "package_api_docs", that is enabled as well via all being enabled.
    # https://dart.dev/tools/linter-rules/package_api_docs.html
    # "DO provide doc comments for all public APIs.", is what it is supposed to do, but only for
    # packages. However, if we turn OFF the rule "public_member_api_docs", then the
    # "package_api_docs" offers no warnings on missing API doc comments alone. So our conclusion
    # for now is that this rule has to be used instead to ensure we find all APIs that should
    # have documentation comments in a package as well.

    # DO sort constructor declarations before other members.
    #
    # We do like this lint rule, but we want to have the default constructor first, followed
    # by its properties, after this, other named constructors and factories. This rule gets
    # in the way of that and forces you to put (often final) constructor properties after all
    # the named constructors and factories, making them tedious to find and disconnected from
    # where we want to see, read and handily edit them. This is especially the case if there are
    # many constructors and factories, and they have a lot of parameters. For now, we disable
    # this rule and order things as described above, which apart from the default constructor
    # properties coming right after the constructor, is the only part where we in practice
    # deviate from this rule, so other yes, we do put constructors first as well anyway.
