This document summarizes an introductory Flutter session. It introduces Rayen Zegden, who is a GDSC member and mobile development lead, and explains that the goal is to create performant, easy to use, and efficient applications. It provides definitions of Flutter as an open-source framework for building mobile apps using Dart, and widgets as visual elements. Advantages include fast development, a single codebase, and customization, while disadvantages include limited libraries and a steep learning curve. Finally, it previews setting up tools and libraries needed for a first Flutter application.

Flutter planning
What is Flutter? ● Flutter is an open-source mobile application development framework created by Google. ● It is used to develop cross platform applications from a single codebase for any web browser, Android, iOS… ● Flutter uses the Dart programming language, which is also developed by Google.
Our goal is to create applications. Applications that are performant , easy to use and efficient .
Advantages of Flutter ➔ Fast development cycle ➔ Single codebase for multiple platforms ➔ Customizable Widgets ➔ High performance
Disadvantages of Flutter ➔ Limited third-party libraries ➔ Steep learning curve ➔ Limited corporate adoption
Flutter Dart Purpose Flutter is a framework for building mobile applications. Dart is a programming language.
Flutter Dart Architecture Flutter uses a widget based architecture where everything is a widget. Dart is designed to support many programming languages such as Java or C++.
● In flutter a widget is a description of a part of a user interface. ● It is a building block for creating the visual elements of an app , such as buttons , text, images… ● There are two types of widgets: -Stateless widgets - Stateful widgets What is a widget ?
