7.1 README & Setup Instructions

Status: ❌Fail

Findings:

  • Minimal README: README.md exists but contains only basic template information
  • Outdated information: README mentions "Moor database engine" but project uses Drift (outdated)
  • Missing critical setup information:
  • No Flutter version requirements (FVM setup)
  • No environment variable configuration
  • No Firebase setup instructions (only command without context)
  • No iOS/Android specific setup steps
  • No dependency installation instructions
  • No build instructions for different environments
  • Incomplete getting started guide: Only mentions running build_runner for code generation
  • No development workflow documentation: Missing information about Git workflow, branching strategy, code review process
  • No troubleshooting section: No common issues or solutions documented
  • No contribution guidelines: Missing information for new developers joining the project
  • No environment configuration: Missing instructions for setting up staging vs production environments
  • No CI/CD documentation: No explanation of build pipeline or deployment process
  • Template README: README appears to be a template from Markedeer base profile project, not customized for SuperTank

Evidence:

  • README.md contains only:
  • Project title: "profile" (generic, not SuperTank-specific)
  • Description: "This is Markedeer's base Android/iOS Flutter profile project"
  • Outdated: Mentions "The Moor database engine" (project uses Drift)
  • One "Getting Started" section with single command: fvm flutter packages pub run build_runner build --delete-conflicting-outputs
  • Firebase setup command without context or explanation
  • Splash screen generation command
  • Missing sections:
  • Prerequisites (Flutter, FVM, Xcode, Android Studio)
  • Installation steps
  • Environment setup (staging vs production)
  • Firebase configuration details
  • Build instructions
  • Running the app
  • Testing instructions
  • Deployment process
  • Troubleshooting
  • Architecture overview

Risk Level: Medium Risk

Recommendation:

  • Immediate actions:
  • Update README to be SuperTank-specific (remove template content)
  • Fix outdated information (change "Moor" to "Drift")
  • Expand README with comprehensive setup instructions
  • Add prerequisites section (Flutter version 3.24.5, FVM, development tools)
  • Document environment configuration (staging vs production)
  • Add Firebase setup instructions with context
  • Short-term:
  • Document build process for Android and iOS
  • Add development workflow documentation
  • Include troubleshooting section with common issues
  • Document how to run tests (once implemented)
  • Long-term:
  • Create separate documentation for architecture and design decisions
  • Document deployment process and CI/CD pipeline
  • Add developer onboarding guide
  • Document API integration and backend communication

7.2 API Documentation

Status: ❌Fail

Findings:

  • No API documentation file: No separate documentation for API endpoints
  • API endpoints defined in code only: Endpoints visible in Retrofit-generated code and route models but not documented
  • No request/response documentation: No documentation explaining request parameters, response formats, or error codes
  • Base URLs not documented: API base URLs defined in config.dart but not explained
  • OAuth2 flow partially documented: Token refresh logic has some inline comments but lacks comprehensive documentation
  • No API versioning documentation: No information about API versions or backward compatibility
  • Error responses undocumented: No documentation of error response formats or status codes
  • No API examples: Missing example requests and responses for developers
  • Retrofit annotations: API endpoints defined using Retrofit annotations but no documentation explaining usage

Evidence:

  • lib/utils/config.dart: Defines base URLs for staging and production but no documentation
    • Production: https://www.supertankoranjeboven.nl
    • Staging: https://staging.supertankoranjeboven.nl
  • lib/singletons/dio_singleton.dart: Contains some inline comments for OAuth flow (lines 54-55, 60-61, 65-66, 72-73, 78-79, 90-91, 97-99) but lacks comprehensive documentation
  • Route models in lib/route_models/ (30+ files) define API interactions but lack documentation
  • No API documentation file (e.g., API.md, docs/api.md)
  • No OpenAPI/Swagger specification
  • No Postman collection or API examples
  • OAuth2 authentication flow partially documented with inline comments but missing request/response formats
  • Error handling in Dio interceptor (lines 93-102) has minimal comments but no comprehensive error documentation

Risk Level: Medium Risk

Recommendation:

  • Immediate actions:
  • Create API documentation file documenting all endpoints
  • Document request/response formats for each endpoint
  • Document authentication flow and token management
  • Document error response formats and status codes
  • Document base URLs and environment configuration
  • Short-term:
  • Add inline documentation to route models explaining each API interaction
  • Document OAuth2 authentication flow comprehensively
  • Create API examples showing request/response pairs
  • Document error codes and handling strategies
  • Long-term:
  • Create OpenAPI/Swagger specification
  • Provide Postman collection for API testing
  • Document API versioning strategy
  • Document rate limiting and usage guidelines

7.3 Code Documentation

Status: ❌Fail

Findings:

  • Minimal code comments: Very few code comments throughout the codebase
  • No function/class documentation: Most functions and classes lack documentation comments
  • Some inline comments: Limited inline comments exist, mostly for workarounds or complex logic
  • No parameter documentation: Function parameters not documented
  • No return value documentation: Return values not documented
  • No usage examples: No code examples or usage documentation
  • TODO comments present: Some TODO comments found but not tracked systematically
  • Workaround documentation: Some comments document Flutter workarounds (e.g., gas_station.dart, gas_station_bottom_sheet.dart)

Evidence:

  • lib/singletons/dio_singleton.dart: Has some inline comments (lines 23, 28, 32, 54-55, 60-61, etc.) but functions lack documentation
  • lib/widgets/gas_station.dart: Comments document Flutter workaround (lines 16-19) and TODO (lines 261-262)
  • lib/widgets/gas_station_bottom_sheet.dart: Comments document Flutter workaround (lines 9-12)
  • lib/widgets/supertank_app_decoration.dart: Minimal widget documentation (lines 7-8)
  • lib/routes/login_route.dart: Some comments explaining setup pattern (lines 58-66) but functions lack documentation
  • Most classes, functions, and methods lack documentation comments
  • No @param, @return, @throws documentation tags found
  • No comprehensive class-level documentation

Risk Level: Medium Risk

Recommendation:

  • Immediate actions:
  • Add documentation comments to public APIs and classes
  • Document function parameters and return values
  • Document complex business logic
  • Short-term:
  • Use Dart documentation conventions (/// for public APIs)
  • Document state management classes and their state transitions
  • Document helper functions with usage examples
  • Create documentation for singleton classes and their responsibilities
  • Long-term:
  • Establish code documentation standards
  • Use documentation generation tools (e.g., dart doc)
  • Document architectural patterns and design decisions
  • Create developer guide for codebase structure
