Flutter Tutorial (original) (raw)

Last Updated : 17 Mar, 2025

This **Flutter Tutorial is specifically designed for beginners and experienced professionals. It covers both the basics and advanced concepts of the Flutter framework.

Flutter is Google’s mobile SDK that builds native Android and iOS apps from a single codebase. It was developed in December 2017. When building applications with Flutter, everything is geared towards Widgets – the blocks with which the Flutter apps are built. The User Interface of the app comprises many simple widgets, each handling one particular job. That is why developers think of their Flutter app as a tree of devices.

Compared to contemporary technologies like React Native, Kotlin, and Java, Flutter is much better regarding having a Single Codebase for Android and iOS, Reusable UI and Business Logic, high compatibility, performance, and productivity.

**Prerequisite

Before diving into Flutter, it is important to have a strong grasp of Dart programming, familiarity with Android Studio, and knowledge of web scripting languages like HTML, JavaScript, and CSS.

Flutter - Basics

Flutter is a toolkit created by Google that lets developers build apps for mobile, web, and desktop using the same code. It uses the Dart programming language and comes with ready-to-use widgets for designing user interfaces. Flutter's special feature, hot reload, allows developers to see changes instantly as they code, making development faster. Let us check few basic topics about Flutter.

In this section, you will explore Flutter widgets, which are pre-built elements used to construct user interfaces in Flutter applications. Widgets in Flutter are versatile and customizable, ranging from basic components like buttons and text fields to complex layouts and animations. Flutter provides a rich library of built-in widgets that developers can use directly or customize to suit specific design requirements.

Flutter - Navigation & Routing

In Flutter, Navigation refers to moving between different screens or pages in your app. Flutter provides a powerful and flexible navigation system that allows you to manage navigation stacks, pass data between screens, and handle transitions smoothly. Let us check how navigation and routing work in Flutter.

Flutter - Accessing Device

Here, you will explore how Flutter enables developers to access device features such as cameras, sensors, and storage. Flutter provides plugins that allow easy integration with device hardware and APIs, making it straightforward to utilize functionalities like taking pictures, accessing location data, or storing files locally.

Flutter - Advanced Concepts

In this section, you will explore advanced concepts in Flutter, diving deeper into its capabilities beyond the basics. You'll learn about state management techniques to handle data and user interface changes efficiently. Discover how to integrate Flutter with backend services and APIs to fetch and display dynamic data in your applications. Explore advanced widget customization and animations to create visually appealing user interfaces.

**Flutter App Projects

In this section, you will explore various Flutter app projects that showcase its versatility and capabilities. You'll discover examples ranging from simple to complex applications built using Flutter's user-friendly widgets and robust development tools.
