Mobile App Development (Flutter) interview questions and answers
The most frequently asked Mobile App Development (Flutter) interview questions, with simple answers to help you revise before your interview.
01What is the difference between native and cross-platform apps?
Native apps are built separately for each platform, such as Kotlin for Android and Swift for iOS. Cross-platform frameworks like Flutter or React Native use one codebase for both.
02What is a widget in Flutter?
In Flutter, everything in the UI is a widget. Stateless widgets do not change, while stateful widgets can rebuild when their state changes.
03What is state management?
State management is how an app stores and updates data that affects the UI. Common approaches include Provider, Riverpod, Bloc in Flutter and Redux in React Native.
04How do you call an API in a mobile app?
Use an HTTP client such as the http or Dio package in Flutter, or fetch/axios in React Native, then parse the JSON response and update the UI state.
05How do you publish an app?
Build a signed release, create a store listing with screenshots and descriptions, and submit it through Google Play Console or Apple App Store Connect for review.
