Frequently asked questions

What does a Flutter developer do?

A Flutter developer builds cross platform mobile apps for Android and iOS from a single Dart codebase using Google's Flutter framework. They build widgets and screens, connect to APIs, manage app state and fix bugs. At the entry level they deliver assigned features, test on both platforms and learn Dart and Flutter with support from seniors.

Is Flutter better than native Android and iOS development?

Flutter lets one team build for both Android and iOS from a single codebase, which saves time and cost, so many startups and product firms in India use it. Native development can still be better for heavy platform specific features and performance. The right choice depends on the product, but Flutter demand is strong for cross platform apps.

What language does Flutter use?

Flutter uses Dart, a language created by Google. Dart is easy to pick up if you know a language like Java, JavaScript or C sharp. A fresher who wants a Flutter job in India should learn Dart, the Flutter widget system, a state management approach and API integration, then build a couple of apps to show in a portfolio.
