- Created a new `shared` package to hold `IncrementResponse` and `incrementCallable`. - Updated `https-increment-number/pubspec.yaml` to depend on the `shared` package. - Replaced `https-increment-number/bin/server.dart` with updated user code, fixing syntax errors. - Added appropriate `.gitignore` files to exclude generated Dart tooling and locks.

Code Review
This pull request refactors the Dart HTTPS increment number quickstart by introducing a shared package for common data structures and constants. The server logic was updated to handle both GET and POST requests for a synchronized counter using Firestore atomic increments. Review feedback highlighted a runtime type error when extracting the increment step from query parameters, a discrepancy in the returned count value which failed to account for the step size, and an invalid SDK version constraint in the shared package's configuration.

The cast as int? will cause a runtime TypeError because request.url.queryParameters returns a Map<String, String>. You should use int.tryParse to safely convert the string value to an integer.

The newCount returned in the response should reflect the actual increment value specified by the step variable, rather than being hardcoded to value + 1.

The SDK version constraint ^3.11.0 appears to be a typo, as Dart 3.11 has not been released yet. This will prevent the package from being resolved on current stable Dart versions. Consider using a valid version like ^3.0.0.
