On the other hand, at all times, in a mature company, there is an opportunity to learn quickly inside an already qualified and skilled team working both alone and as a team player.

Speaking of the Flutter developer requirements, here is a list of basic nice-to-have skills for a Flutter software engineer.

So, you can ask a potential candidate:

  • In which ways could you possibly implement the Skia Graphics Engine into the Flutter-based project?
  • What would you build with widgets?
  • How would you craft stateless and stateful conditions?
  • Tell us what you know about the Dart virtual machine.
  • How could you prove a freshly embedded feature functioning in the designated way?
  • What third-party software tools have you managed to integrate into your Flutter project?
  • Could you please describe your work experience in Dart asynchronous programming?
  • Have you ever implemented a “JavaScript bridge” in the Flutter development piece?
  • What is BLoC Flutter? What approaches for managing various states of the application have you dealt with?
  • Could you please articulate your background in using method channels to invoke native API knowledge?
  • Could you please speak about the usage of tools and techniques related to: code analyzers, layout inspector, performance and memory view, multithreading, networking, and security choices.
