Top 5 Flutter 2.2 release updates you should know by now



Flutter, Open sourced UI software development platform, has been rebuilt and refreshed with the current version Flutter 2.2, which has some intriguing new features and capabilities.


This was unveiled during the just-completed Google I/O 2021 event.


Flutter, which was released by Google in 2017, is a cross-platform app development framework that supports Android, iOS, Linux, Mac, Windows, Google Fuchsia, and web-forms all from a single codebase.



Google's Flutter has quickly become the world's most popular cross-platform programming framework. According to Slashdata, Flutter is now used by about 45 percent of all cross-platform developers to create mobile apps.

In fact, usage of the Flutter framework increased by 47 percent between 2020 and 2021, and Flutter is currently used by 12 percent of all mobile apps in the Google Playstore.


Without further fuss, let's go through the top 5 improvements in Flutter 2.2 that you should be knowledgeable of…



  • The use of null safety is now the norm.


Flutter 2.0 included the Null Safety feature, which is now the default for new projects. The Null Safety feature allows developers to simply specify whether a variable or value can be null or not straight from code. It prevents null reference exceptions.The Dart language is used in Flutter, and the compiler is clever enough to eliminate all null-checks in run-time, resulting in a surprisingly fast app.


  • Updated Payment Mechanism.


A significant advancement has been reported in the payment sector for mobile applications built using the Flutter 2.2 version. With the latest version, a new payments plug-in was launched, which was created with the assistance of the Google Play team. Developers may use this handy plug-in to include functionality for accepting payments for tangible items in both Android and iOS apps.Furthermore, the current in-app purchase plug-in has been upgraded with enhanced security and encryption for secure financial transactions.


  • Web Development Gains Strength


Flutter 2.2 offers several intriguing changes in the web development arena. Service workers may now be used for background caching by developers. This means that web-based programmes will be quicker and leaner, resulting in improved performance.


  • Dart Has Been Revised to Include New Features


Dart is a programming language that supports the Flutter development framework for cross-platform apps. It was first published before Flutter.


Dart has been updated to version 2.13 with the release of version 2.2. Dart's support for native interoperability will be expanded with this new release.

This has been made feasible by FFI's support for arrays and packed structs (foreign function interface).


This improvement improves readability and opens the door to refactoring situations.


  • The size of the app can now be reduced.


Flutter 2.2 will now allow Android apps to include delayed components in an effort to make mobile apps even lighter and less bulky. This manner, the Flutter parts required for the app's correct operation may be downloaded at run-time, eliminating the need to load additional code into the app.



Flutter 2.2 now allows iOS developers to precompile shaders, which makes animations more fluid and seamless (when they are run for 1st time). Furthermore, several new tools have been introduced to allow developers to monitor memory consumption in any app, allowing them to optimise memory usage and improve app performance.
