+    # Treat assigning new values to a parameter as a warning. We would almost like to set this
+    # to an error. However, this warning rule or even more so if set to an error, can sometimes
+    # be a bit problematic you include other code directly that does it a lot.
+    # 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
+    # null-safety, the need for this kind of null check and re-assignment to default if null,
+    # is rarely needed. Considering the comment in:
+    # https://dart-lang.github.io/linter/lints/parameter_assignments.html:
+    # "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."
+    # One might even think the rule would allow using the ??= operator, but it does not. For now,
+    # we keep this lint as warning and overriding locally with:
+    #
+    # When we need it for the ??= operator, or some copy/paste in of some code that does things
+    # that needs it too, and that we don't want to deal with fixing at the moment.
