What is Riverpod in Flutter?
Why Interviewers Ask This
Candidates at the intermediate level are expected to not only know this concept but explain the trade-offs involved. Interviewers use this question to see if you can reason about design decisions, not just recall facts.
Answer
Riverpod is a state management library created by the same author as Provider but designed to fix its limitations. Key improvements: providers are globally accessible without requiring a BuildContext, there is no risk of ProviderNotFoundError, providers are strongly typed and testable, and it natively supports asynchronous state with FutureProvider and AsyncNotifier. Riverpod also has compile-time safety with code generation (@riverpod annotation). It is one of the most popular choices for production Flutter apps today.
Pro Tip
Back up your answer with a specific project or situation. Saying 'In my last Flutter project, I used this when...' immediately makes your answer more credible and memorable.
