Code Review
This pull request adds three new sections to the Flutter style guide regarding private named parameters, primary constructors in framework widgets, and in-body constructor syntax. The review feedback correctly identifies that these additions contain major inaccuracies: using private named parameters as initializing formals can break public APIs, and the described primary constructor and in-body constructor syntaxes are not valid Dart features.
