Flutter is an open-source UI toolkit created by Google in 2017 that allows developers to build mobile, web, and desktop applications from a single codebase using the Dart programming language. It provides customizable widgets and tools to build beautiful and high-performance user interfaces as well as features like hot reload that improve developer workflow.

1. Introduction to Flutter
Flutter is an open-source UI software development kit created by Google
in 2017 . It is used to develop applications for Android, iOS, Linux, Mac,
Windows, Google and the web from a single codebase. Flutter uses the
Dart programming language and provides a rich set of pre-built,
customizable widgets for building high-performance, beautiful user
interfaces.

2. What is Flutter?
Cross-Platform
Development
Flutter allows developers to
create native interfaces for
multiple platforms from a
single codebase, reducing
development time and effort.
Rich and
Customizable UI
It offers a wide range of
customizable widgets and
tools to build expressive and
flexible user interfaces.
Hot Reload Feature
Flutter's hot reload feature
allows developers to see the
effects of changes in the
code instantly without
restarting the app.

4. Introduction to Dart programming
language
1 Object-Oriented
Dart is an object-oriented language with classes and interfaces, making it
suitable for building scalable and structured applications.
2 Strongly Typed
It is a statically typed language, providing type safety and efficient execution
by catching potential errors at compile time.
3 Asynchronous Programming
Dart supports asynchronous operations with features like Futures and
Streams, enabling the development of responsive and non-blocking apps.

5. Flutter basics: Widgets and UI
Widgets
Flutter widgets are the
basic building blocks for
constructing the user
interface of an application.
They are customizable and
can be combined to create
complex UI designs.
Material Design
Flutter implements Material
Design, providing ready-to-
use, beautiful UI
components for developing
apps with a consistent
visual language.
Cupertino Style
For iOS & Android apps,
Flutter offers Cupertino
widgets that mimic the iOS
design aesthetics and
behaviors. This ensures a
native and familiar
experience for iOS users.

6. Understanding Flutter's
Stateless & Stateful
Widgets
Flutter provides two fundamental types of widgets for building user
interfaces: Stateless and Stateful widgets. Stateless widgets are
immutable and don't maintain any internal state, while Stateful widgets
can change over time. Learn how to use these widgets effectively to
create dynamic and interactive UIs in Flutter.

7. Building a simple Flutter app
1 Create a New
Flutter Project
Use the Flutter CLI to
create a new project. It
will set up the basic
structure for your app.
2 Design UI with
Widgets
Use Flutter's rich set
of widgets to design
the user interface of
your app, focusing on
the user experience
and visual appeal.
3 Implement
Functionality
Write Dart code to add
functionality to your
app, such as handling
user interactions and
data processing.
