We are expected to have good knowledge of native Android development: that is if we want to develop very fine and detailed applications in Flutter. Also, we should have a solid understanding of OOPS(Object-Oriented-Programming) concepts. We should be well versed with appropriate knowledge of Git and the use of GitHub, candidates should understand the fundamentals of Computer Science, understand the software development life cycle, have strong knowledge of different architecture approaches, and knowledge of SQL as a database is equally important.
