Flutter is an open-source UI toolkit developed by Google for building natively compiled applications across mobile, web, and desktop platforms using a single codebase. It allows for cross-platform development with features like a widget-based system and hot reload, enhancing interface creation and developer productivity. However, its downsides include larger app sizes, fewer third-party libraries, and potential performance discrepancies between Android and iOS.

2. NATIVE APP AND HYBRID APP
• Native app is developed for a particular platform.
• Uses languages that are native to platform.
• They are generally faster and responsive than hybrid apps.
• Example:
i) App developed in iOS using swift.
ii) App developed in android using Kotlin.

3. NATIVE APP AND HYBRID APP
• Hybrid app combines the features of both native and web apps.
• Type of cross-platform app development
• It uses web technologies such as HTML,CSS and JavaScript.
• Hybrid apps are developed using frameworks such as React
Native,Xamarin etc.
• Allows developers to create apps that can run on both android and
iOS.

4. • Cross-platform development refers to the practice of creating software
applications that can run on multiple operating systems or platforms.
• This allows developers to write code once and deploy it across various
platforms.
• This saves time and reduce effort compared to building separate versions
for each operating system.
WHAT IS A CROSS-PLATFORM APP DEVELOPMENT ?

6. WHY FLUTTER ?
o Google's UI Toolkit: Flutter is an open-source UI
toolkit developed by Google for building natively
compiled applications for mobile, web, and
desktop from a single codebase.
o Cross-Platform Development: Flutter enables
developers to write code once and deploy it
across multiple platforms.
o Dart Programming Language

7. WHY FLUTTER ?
o Flutter’s widget-based system makes it simple to create great-looking
interfaces, and it works well on different platforms.
o . Hot Reload Feature: This allows developers to instantly see changes made to
the code reflected in the app's UI without restarting the application.
o Flutter aims to provide 60fps performance or 120fps performance on a device
capable of 120hz.
o This framework is popular for being flexible, easy to learn, and great for
making custom designs.

8. One Codebase for all the Platforms.

9. Dart Programming Language: The Backbone of Flutter
o Designed for Productivity and Performance: Dart is engineered
to strike a balance between developer productivity and application
performance.
o Familiar Syntax for JavaScript and Java Developers
o Supports Both JIT and AOT Compilation: Dart supports both Just-
In-Time (JIT) and Ahead-Of-Time (AOT) compilation, offering
flexibility in how Flutter applications are compiled and optimized
for performance.

11. WHAT ARE THE DOWNSIDES OF USING FLUTTER?
o Large apps : Flutter apps carry all the needed code to run the app, making
them bigger than other apps that rely on platform elements.
o Lack of third-party libraries : Flutter has a wide range of built-in widgets,
and its official package site offers thousands of choices. However, since
Flutter is still relatively new, there are fewer resources for third-party
libraries compared to other development tools.
o It may be better for Android than iOS : It’s not unexpected that Flutter’s
performance might lean more towards Android than iOS. Some instances
already show iOS features trailing behind as Flutter updates are rolled out.
