Why Flutter enables cross-platform development - Quick Recap

Recall & Review

beginner

What is Flutter's main advantage for cross-platform development?

Flutter allows developers to write one codebase that runs on both iOS and Android, saving time and effort.

intermediate

How does Flutter render UI on different platforms?

Flutter uses its own rendering engine called Skia to draw UI components directly on a canvas, ensuring consistent look across platforms.

intermediate

Why does Flutter not rely on native UI components?

Flutter draws its own widgets instead of using native components, which helps maintain consistent design and behavior on all platforms.

beginner

What programming language is used in Flutter for cross-platform apps?

Flutter apps are written in Dart, a language designed for fast development and smooth performance.

advanced

How does Flutter achieve high performance on multiple platforms?

Flutter compiles Dart code to native machine code, which runs fast and efficiently on both iOS and Android devices.

What engine does Flutter use to render its UI?

A Blink

B WebKit

C Skia

D Gecko

Flutter uses the Skia engine to draw UI components directly on a canvas.

Which language do you use to write Flutter apps?

A Dart

B JavaScript

C Kotlin

D Swift

Flutter apps are written in Dart, which is optimized for UI development.

Why does Flutter provide consistent UI across platforms?

A It uses native UI components

B It uses a web view

C It uses platform-specific code for each OS

D It draws its own widgets using a rendering engine

Flutter draws its own widgets using the Skia rendering engine, ensuring consistent UI.

What is a key benefit of Flutter's single codebase?

A Requires separate code for iOS and Android

B Speeds up development by sharing code across platforms

C Only works on Android

D Needs manual UI adjustments for each platform

Flutter's single codebase speeds up development by allowing code reuse on iOS and Android.

How does Flutter achieve fast app performance?

A Compiles Dart to native machine code

B Runs apps inside a browser

C Interprets code at runtime

D Uses Java Virtual Machine

Flutter compiles Dart code ahead-of-time to native machine code for fast performance.
