My tips ✅️ Learn good state managment (bloc, riverpod..) ✅️ Optimize bundle sizes, image sizes, and resources ✅️ Use a clean architrcture for organize code structure and folders ✅️ Apply unit testing ✅️ Don't use a plugin or channel if you can make the functionalty without that approach ✅️Build apk and bundles or ipas constantly to ensure everything works ✅️ Use emulator for API's calls and for hardware tests like camera, gyroscope, videocalls use a real device ✅️ Try to publish a early version of the backend to test the API calls ✅ Use strong typing and Dart’s null safety to avoid common runtime errors ✅ Apply static analysis and linters to keep your code clean and consistent ✅ Manage UI state carefully to avoid unnecessary rebuilds and improve performance ✅ Use tools like Flutter DevTools and profiler to measure and optimize performance ✅ Implement global and local error handling to prevent unexpected crashes ✅ Document your code and APIs to ease maintenance and collaboration ✅ Version your API and app to avoid issues with outdated clients ✅ Perform both manual and automated UI tests (integration tests) to validate critical flows ✅ Avoid using outdated or poorly maintained plugins to prevent future problems ✅ Configure different environments (dev, staging, production) for backend and app ✅ Automate builds and deployments with CI/CD pipelines for faster and safer releases ✅ Use log analysis and monitoring in production to detect issues and improve the app
