What is Flutter (Collection)

1. Structure and Language

Flutter uses the Dart programming language, a modern language developed by Google. Dart is compiled to native code, enabling Flutter apps to run smoothly and efficiently across various devices. Dart supports features like functional programming, object-oriented programming, and flexible function programming.

2. Widget

Flutter is based on a concept called “widget,” which are the basic components for building user interfaces. Widgets in Flutter can be components such as buttons, text boxes, sliders, layouts, or even complex widgets like a login screen or a list fetching API calls.

3. Technical Features

Flutter uses its own graphics engine called Skia to draw user interfaces. This helps Flutter achieve optimal performance and consistency across different platforms. Flutter does not rely on native OS UI components from Android or iOS; instead, it redraws all components from scratch.

II. Why Develop Mobile Apps with Flutter?

Developing mobile apps with Flutter is considered a sensible and worthwhile choice for several important reasons:

1. Single Codebase, Multiple Platforms

Flutter uses Dart programming language to build apps with a single codebase that runs on both iOS and Android. This approach reduces development time and maintenance efforts significantly compared to maintaining separate codebases for each platform. Developers can write once and deploy on multiple platforms, which streamlines the development process and ensures consistency across devices.
