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 to build native iOS and Android apps from a single codebase. It was developed on December 4, 2018. When building applications with Flutter, everything is 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 Flutter developers tend to think of their Flutter app as a tree of devices.

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

Flutter – Basics

In this section, you’ll learn the fundamentals of Flutter. 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.

Flutter – Widgets

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 – Design & Animations

Here in this section, you’ll learn how to use these widgets to design buttons, text fields, and other elements that look great on both Android and iOS devices. Additionally, Flutter’s powerful animation capabilities allow you to create smooth transitions and interactive effects, enhancing the user experience.

Flutter – Forms & Gestures

You’ll learn how to validate user inputs and handle form submissions efficiently. Additionally, Flutter simplifies the implementation of gestures like tapping, swiping, and pinching, enhancing user interaction within your applications.

In this section, you will explore how navigation and routing work 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.

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 – Advance Concepts

Here 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
