One common Flutter development mistake is not managing state properly. Beginners often rely too heavily on setState, leading to bloated widgets and performance issues. Choosing the right state management approach, like Provider, Riverpod, or Bloc, early in the project is crucial for scalable, maintainable code. Poor widget structuring can also make the UI hard to read and debug. Another frequent issue is neglecting platform differences. Flutter supports both iOS and Android, but developers sometimes ignore platform-specific behaviors, leading to inconsistent UX. Additionally, overlooking performance optimizations, like excessive rebuilds or improper use of async methods, can result in laggy apps and frustrated users. visit: https://www.iroidtechnologies.com/hire-a-developer/hire-flutter-developer
