2. Flutter is an open-source software development kit that enables fast and simple
cross-platform mobile app development. You can quickly build high quality
natively compiled apps for iOS and Android, without writing separate code for
both apps. All you need is a codebase for both the platforms.
Last year, Tim Sneth, Product Manager for Flutter, announced the growing use of
Flutter with over 2 million developers using the toolkit since its release in 2018.
The Spring Update also shows that it is seeing growth not only in consumer apps
but also in enterprise apps. Development.
In this presentation we are going to introduce Flutter development language. We
will tell what is flutter, and we will tell about its advantages and disadvantages.

3. What is Flutter?
In the time of Objective C/Swift and Java/Kotlin as primary languages for mobile
development, building apps was expensive. You had to build two separate apps, which
obviously meant working twice.
To solve this problem, several frameworks have been created for building hybrid (or cross-
platform) apps in HTML5 and Javascript. Among cross-platform toolkits including
PhoneGap, Xamarin, React Native, and more, the Flutter framework has become
increasingly popular among developers, enterprises, entrepreneurs, and users.
Flutter is a portable UI toolkit for building native-like apps on mobile, web and desktop
from a single codebase. Flutter uses the programming language Dart and incorporates
Material Design and Cupertino widgets. Flutter developers can create great UI that looks
and feels native. It behaves naturally on any platform, regardless of the one codebase you
are using.

4. Flutter is the only framework with a mobile SDK that provides a responsive style without
using a JavaScript bridge, reaching a level of performance that rivals its cousin and direct
competitor, React Native. It easily integrates with various platforms such as Android, iOS
and Linux, Mac, Windows and Google Fuchsia applications.
What is Flutter?
Flutter is one of the best solutions for developing apps for Android and iOS without having
to write in a separate codebase for each platform. Smartphone versions of these apps
function as true, native apps on Apple and Android devices and are compiled for the
respective platforms prior to publication. They don't require runtime modules or browsers.
Using the same codebase, it is also possible to build web apps for browsers as well as native
programs for Windows, Linux, and macOS.
Google itself uses Flutter for many of the modules of the Google Assistant and for the user
interface of the Google Home Hub. Well-known e-commerce service providers such as
eBay, Groupon or Alibaba Group use Flutter to give a uniform look to their mobile and web
apps.

5. What programming language is Flutter based
on?
The Flutter SDK is based on the Dart programming language, also developed by Google. It is
intended to replace classic JavaScript. On a server, Dart programs can be run directly, while
in the browser they are converted to JavaScript using the Dart2JS transcompiler.
Apps for Google's new platform Fuchsia are developed directly with Dart. Its structure is
similar to that of well-known object-oriented programming languages ​​such as Java or C#.
It’s All Widgets: The Flutter principle
Flutter is a widget-based technology. This means that you can apply object-oriented
programming to any element. One of the benefits of using Flutter is that you can easily modify
or customize widgets. In addition, it provides UI widgets that meet the major web application
design requirements.

6. Pros and cons of Flutter app development
Every programming language has its advantages and disadvantages. But, in most
cases, we can say that the advantages of Flutter clearly outweigh its disadvantages
compared to similar technologies.
Pros of Flutter app development
Flutter has many advantages over its competitors. These advantages lie in the programming
language and set of development tools that allow Flutter to solve issues that other languages
may not cope with.
Flutter, as an open-source framework, has attracted a wide and active community of
developers since its release. This community constantly publishes usable code examples and
supports developers in building new, innovative, beautiful cross-platform apps.

7. Cons of Flutter app development
There are no impeccable technology solutions, and Flutter is no exception. Flutter's cons aren't
exactly a deal-breaker, but here are a few reasons why it might not be the ideal toolkit for a
specific app.
 Large file size because of the widgets
 Complex updating
 Limited set of tools and libraries
 One codebase for all platforms
 “It’s all Widgets” principle offers countless possibilities
 Rich libraries
 Fast testing with hot reload
