Flutter vs React Native comparison - Quick Revision & Key Differences

Recall & Review

beginner

What is Flutter?

Flutter is an open-source UI toolkit by Google for building natively compiled applications for mobile, web, and desktop from a single codebase using the Dart language.

beginner

What is React Native?

React Native is an open-source framework by Facebook that allows developers to build mobile apps using JavaScript and React, sharing code across iOS and Android.

How does Flutter render UI compared to React Native?

Flutter uses its own rendering engine to draw widgets directly on the screen, while React Native uses native UI components of the platform through a bridge.

intermediate

Which language does Flutter use and why is it beneficial?

Flutter uses Dart, which is easy to learn, supports ahead-of-time compilation for fast startup, and just-in-time compilation for hot reload during development.

intermediate

What is a key advantage of React Native's approach to UI?

React Native uses native UI components, so apps often feel more like native apps and can reuse existing native code or libraries easily.

Which language is used by Flutter for app development?

A Dart

B JavaScript

C Java

D Swift

Flutter uses Dart language for building apps.

How does React Native render UI components?

A Draws UI with its own engine

B Uses native platform UI components

C Uses HTML and CSS

D Uses canvas drawing

React Native uses native UI components of the platform.

Which framework provides hot reload for faster development?

A Both Flutter and React Native

B Flutter only

C React Native only

D Neither

Both Flutter and React Native support hot reload to speed up development.

What is a benefit of Flutter's own rendering engine?

A Runs only on Android

B Uses native UI components

C Better control over UI appearance

D Requires less memory

Flutter's engine allows consistent UI across platforms with full control.

React Native apps are primarily written in which language?

A C#

B Dart

C Kotlin

D JavaScript

React Native apps use JavaScript with React.
