Code Review
This pull request updates the Flutter style guide regarding variable and parameter types, specifically introducing a policy to omit type annotations for local variables when the type is obvious from context. Review feedback suggests renaming the section title to 'Variable and parameter types' to resolve a contradiction with the new guidance and removing references to non-existent lint rule identifiers to prevent developer confusion.
