• Compare state-management approaches using Provider, Riverpod, Bloc or GetX, and explain architectural trade-offs.
• Check platform channels, FFI and native integrations, including relevant web, desktop or embedded targets; diagnose performance issues in animations and large lists.
• Record the assumptions, supporting evidence and corrections needed for another specialist to follow your review.
Experience and expertise
• Professional background of at least 4 years in Flutter development with production apps.
• Practical depth in Dart, including null safety, isolates, and async streams.
• Experience with at least two state management approaches in Flutter.
• A thorough understanding of Flutter's render pipeline and widget lifecycle.
