Sensitive files in repository - Keystore file (`gulfforyou.keystore.jks`) stored directly in repository. Risk of credentials being exposed in version control history.

Move keystore file to centralized secrets management. Remove from repository and add to .gitignore. Rotate keystore if it has been exposed. Ensure keystore is only accessed via Codemagic secrets management.

Complete absence of test suite - No unit, integration, or UI tests exist. Business logic and UI components are untested, creating high risk of regressions.

Implement comprehensive test suite: 1) Golden tests for UI consistency, 2) Unit tests for business logic, 3) Integration tests with mock data and staging environment. Add test execution to CI/CD pipeline. Create test directory structure and uncomment flutter_test dependency.

Unencrypted sensitive data storage - Access tokens, refresh tokens, usernames, UIDs, and email addresses stored in plain text in SQLite database. No encryption at rest for sensitive user data.

Migrate sensitive data to flutter_secure_storage. Use Android Keystore/iOS Keychain for credentials. Encrypt database file or sensitive columns using SQLCipher. Remove plain text storage of tokens and credentials.

No automated testing in CI/CD - Builds can succeed even with broken code. No quality gates in build process. No test execution steps in Codemagic workflows.

Add test execution steps to Codemagic workflows. Run unit tests, widget tests, and golden tests before building. Fail builds if critical tests fail. Add linting and static analysis steps.

Deprecated libraries - Deprecated packages (package_info) require migration. Many packages have major version updates available but are constrained to older versions. Beta packages in use.

Migrate package_info → package_info_plus. Move from beta to stable versions of flutter_html and flutter_html_iframe. Plan migration for major version updates. Resolve dependency overrides. Create upgrade plan with testing strategy.

Code duplication - Firebase Performance tracing duplicated across multiple routes. Route setup patterns, FutureBuilder patterns, and error handling duplicated. Singleton access patterns repeated.

Extract Firebase Performance tracing into base route class or mixin. Create reusable widgets for common UI patterns. Extract common route patterns into base classes. Consolidate singleton access patterns.

State management performance - State stored in both memory and database, potential for inconsistency. State persistence to database happens on every state change, impacting performance.

Review state synchronization between memory and database. Add state validation to prevent inconsistencies. Consider batching database writes for performance. Consider dependency injection instead of singletons for better testability.

Memory management improvements - Image.memory() usage without size limits, state persistence on every change, some dispose methods implemented but not all.

Add memory limits for image loading. Optimize state persistence (batch updates). Review all dispose methods for completeness. Add memory profiling.

Localization improvements - Only Dutch locale supported, hardcoded strings throughout codebase. Localization infrastructure exists but not fully utilized.

Extract hardcoded strings to translation files. Create .arb files for Dutch. Implement proper localization system. Plan for additional languages if needed.
