Know the latest updates of Flutter 2.2 and how it will help developers to develop applications effectively.

1. Everything You Need to Know About
Flutter 2.2
Today one of the largest and the most used platforms for
cross-platform app development is Flutter. Google’s constant
efforts to make the Flutter framework better is making it more
useful. Every few months, Flutter is launching new things to
make their ecosystem stronger and easier to use for
developers. This has made it a go-to solution for developers to
develop cross-platform applications using a single-codebase.
Today, it is the second most used framework globally and has
one of the largest communities of developers.

2. Its open-source nature, ease to learn and use makes it
everyone's favorite.
After a break of a year, Google came back this year with
Google I/O, its much-awaited annual developer conference.
This year it took some of the significant leaps in the various
sectors like AI, ML, Quantum Computing, Material Design,
Flutter, and plenty of others. Each of its products has some
significant new features, which hopefully make the future of
technology brighter.
Herein, I will throw some light on Flutter and its major
updates, which make the Flutter ecosystem stronger and
provide a better developing experience.
Flutter’s major aim is to provide ambient computing, which
helps developers to develop interactive, intuitive, and
feature-rich applications easily. This year their main aim was
to make the ecosystem more robust and more secure than
before. The flutter team is very active and constantly works on
the feature requirements from its developer circle. Listening
to developers’ requests, in Flutter 2.2, the team has made
major changes that help developers.

3. New Updates in Flutter 2.2:
Flutter and Material YOU:
The Flutter team works closely with the Material design team
to bring more versatility to the framework in terms of design.
The new design named Material YOU supports Flutter which
means, developers can develop their applications using
Material YOU which provides users more personalization.
In simple terms, Flutter developers can get access to the new
and old but tweaked widgets for Material YOU. Once the new
design language releases its beta version, it will be available to
use in your Flutter applications. Developers starting out with
Flutter App Development can easily develop using Material
Design and provide better experience to the user. The
open-source nature of both platforms makes it easy to develop
an application.
Integrating Payments:
For years, developers were asking the Flutter team for
payment options, and finally, it is here. Flutter now supports
integration with multiple payment modules like Google Pay,
Apple Pay, and In-App Purchases. Instead of following multiple

4. steps to integrate payment modules, developers can use a
single-codebase to develop and integrate it. Now, developers
can also provide in-app purchases to their customers and
make the payment process simpler. With the new update, the
Flutter team has made the in-app purchase eco-system
stronger by updating the documentation, building code labs,
and re-architectured the plugin.
Ads:
Monetizing an application is one of the important parts.
Google Mobile Ads SDK was first available in the beta version,
and developers loved it. In version 2 Flutter team has brought
some new changes.
Flutter has migrated the GMA SDK and enabled null safety,
which helps developers handle exceptions easily and be
productive while developing applications. It also supports the
latest iOS GMA SDK, which adds App Tracking Transparency in
the applications. This makes it easy for developers to develop
iOS applications by abiding by all laws of the iOS platform
easily. Last and the biggest new feature is Adaptive Banner,
which is a new way of responsive ads. This will help developers

5. to maximize their app performance by making it responsive.
So, now regardless of the device, you are building your
application for, you can use Adaptive Banner using a
single-codebase.
Flutter Flow:
For years now, developers have been requesting a Flutter
layout to develop applications fast and easily, directly in the
browser. Flutter Flow allows developers to start with Flutter
app development and build applications faster, easier, and with
less code. This makes development fun for developers, and
anyone and everyone can learn it easily. You can easily develop
different UIs for your application. Flutter Flow uses Firebase
authentication and Firebase database to store your
information securely. Now, you can easily develop applications
in less time and provide a better user experience.
Flutter UWP (Universal Windows Platform):
Flutter has now extended its support to Windows UWP, which
helps developers easily start with the Windows platform’s
Flutter app development.

6. Yes! You read it right. You can now develop applications for
multiple Windows platforms like Windows 10, Xbox, and
HoloLens. Instead of developing for multiple Windows
platforms, using UWP, you need to write code only once. This
is still an early Alpha version of Flutter UWP. To use it, set up
UWP prerequisites, and go to the dev channel on Github to
enable it. Still, the Flutter team has to update and bring many
new features in the UWP, making it more stable and
interesting to build applications. Let’s wait for future updates
on Flutter UWP.
Null Safety:
Null Safety is an essential part of the development to handle
any kind of exceptions. It helps in increasing productivity by
helping developers build applications faster and handle
exceptions. Dart is a typeface programming language which
means depending on the variable declared, it can know which
data type it is. But, it could not develop null data variables due
to which many exceptions were occurring and reported on the
Github repository. Further, to solve these exceptions, there
were thousands of commits to fix this issue. As a result, it was

7. hindering developers’ productivity and not helping them have
a stronger ecosystem.
To avoid these issues and build a stronger ecosystem, Flutter
made Null Safety default. This means now developers don’t
need to worry about handling exceptions and developing
efficiently. Null safety works on three core principles:
● Non-nullable by default: Unless you tell that the variable
is null, it will be considered non-nullable.
● Incrementally adaptable: You can have null safe and
non-null safe products in the same project.
● Fully sound: Dart’s null safety is fully sound, meaning you
can depend on it and rely on its type system. Once you
migrate your full project, you will find smaller bugs and
faster execution.
These principles help make Dart and Flutter a stronger
ecosystem.

8. Miscellaneous Updates:
Apart from the major updates, there are certain minor
updates, making the framework fun and easy to learn.
Following are some of the miscellaneous updates:
● New Material Icon:
With the new updates, there are more than 7000 icons for
your application. You can efficiently search for any of them
using the search bar, and from now onwards, there are also
Dash icons available for your application. You can download
icons from here.
● Automatic Scrolling Behavior:
Mobile phones don't need scrollbars, be it iOS or Android, but
on a desktop, it needs scrollbars. Hence, many time developers
need to call the in-built scrollbar widgets. But, with the new
release, you can go without scrollbars. With this release, the
application automatically takes the scroll bar, depending on
your application’s content. If you are not happy with the

9. default scrollbar, you can change the theme according to your
desire.
● Mouse Cursors:
With the new version, you can make rich text applications that
can help you to make the cursor more interactive. If you are
using TextSpan with gesture recognizer you will automatically
get the corresponding cursor.
These updates may look pretty small but have a huge impact.
Such small updates collectively help in making intuitive and
interactive applications and provide a better user experience.
Conclusion:
With every new release of Flutter, the ecosystem is becoming
stronger than before. With Flutter version 2, we can see some
major changes coming for the developer circle, which will have
a major impact on the future of app development.
Moreover, the recent collaboration between Google and
Samsung for building smartwatches can also open the
gateways for building smartwatch applications using Flutter.

10. This shows that the roadmap of Flutter is stronger, and with
time we can expect the framework to mature.
