Job description
About the Role
We’re looking for a smart, detail-oriented Flutter Developer who loves building high-quality mobile experiences. You’ll be working on our next-gen Fintech & Investment app, focusing on clean architecture, strong session management, and secure code implementation.
Responsibilities
Build and maintain production-level Flutter applications for Android and iOS.
Develop pixel-perfect UI with smooth animations, transitions, and responsive layouts.
Implement secure session management, authentication, and token-based APIs.
Work closely with the backend (Node.js) and API teams for smooth data integration.
Optimize app performance and memory usage.
Follow secure coding standards suitable for fintech products.
Collaborate with design and product teams to improve UX and app flow.
Integrate third-party SDKs and payment gateways (Razorpay, Cashfree, etc.).
Use version control (Git) and agile workflows effectively.
Must-Have Skills
1–3 years of hands-on experience with Flutter & Dart.
Strong knowledge of state management (preferably Riverpod or Bloc).
This guide is for Flutter developers in India preparing for interviews, from freshers applying for their first mobile developer role to engineers with several years of experience moving into senior positions. It has 60 questions split into easy, medium and hard levels, each with a sample answer written the way a strong candidate would explain it, plus Dart code where it helps. Topics follow Flutter 3 and Dart 3: widgets, layout, navigation, state management with Provider, Riverpod and Bloc, async code, isolates, platform channels, performance, testing and release builds. Read each answer, then practise explaining it aloud in your own words.
