Here Comes Flutter 2.2 – The Latest To Join The Bandwagon

Flutter 2.2 is based on the foundation of Flutter 2 and with it, enterprises and startups, alike, will be able to create effective solutions across the market, fulfilling their organizational requirements with ease. This latest release focuses on enhancements to the developer experience in terms of more reliability, performance, and customer satisfaction. It is more of a service update, with a stringent look for stability and fine-tuning of current features rather than adding new ones.

There is a new guideline on how best to support different kinds of platforms through a unified source codebase. All these features are present in stable and accessible production apps.

There is an increasing number of Google-based products that have been leveraging Flutter and that has been highlighted in the I/O conference.

Here are the key highlights of Flutter 2.2.

  • Enhancements In Performance:

There are certain improvements in the performance criteria with this latest release of Flutter. Web applications can perform background caching with the help of service workers, Android and iOS developers can avail certain specific features with which performance will be bettered.

There is a DevTools suite that can enhance performance through a specific set of features that will better memory allocation during runtime. Basically, all improvements are focused on offering users a faster application loading experience with better performance across different platforms. There is an addition of support for third-party extensions that has earlier been shown by peer organizations involved in Flutter development.

  • The New Ads SDK Is Here:

The newly arrived ads SDK now completely supports null safety that assists developers to prevent null exceptions. It also supports adaptive banner formats, with an updated plug-in and relevant codelab. Null safety will be enabled, by default, for newer projects. This addition of optional null safety will help developers in becoming more confident with the application code. For this, there are over 5000 packages on Dart’s ‘Pub’ package manager, that have been converted to null safety.

  • Tighter Integration With Google’s Ecosystem:

Google is the backbone behind Flutter and with Flutter 2.2, the bond gets stronger. The organization has come up with a new in-app payment plug-in in connection with the Google Pay team. This will facilitate users to process the payment smoothly from within their apps. The same experience will be displayed for Apple Pay for iOS users. This release is assisting in letting developers feel that there is a larger connect of apps with the Google ecosystem, with more collaborations with various partners.

  • Latest Version Of Dart – Dart 2.13 Is Here:

As with all Flutter releases, this release also showcases the most recent Dart update. Dart’s latest version – Dart 2.13 has shown its assistance for native interoperability and type aliases. It also shows support for packed structs in foreign function interface and arrays, with an interface for communication with legacy C code. There is also the inclusion of backing for type aliases that helps in making code highly readable and simpler to refactor. Flutter 2.2 is now bundled with Dart 2.13 that is also available for a separate download.

  • Increased Support For Creation Of Platform Adaptive Apps:

Flutter, not only supports the creation of apps with different platforms or form factors like mobile, tablet, desktop, it also caters to various input types and platforms like system menus, navigation drawers, etc. The new version now can be used to create platform adaptive apps that can easily adjust to the details of various target platforms.

  • Improved Web Platform For Flutter:

Flutter’s latest stable platform, the web has been enhanced with the new release. Caching behavior has been optimized with a novel service worker loading mechanism. Web renderers have been improvised – addition of support for font features for HTML, using canvas APIs for text rendering, support for shader masks, use of opacity masks for transition performance. For better accessibility, semantic node position has been bettered to lessen the gap between desktop and mobile web apps.

  • Enhanced Text Handling:

Text handling did not ask for more importance in earlier versions, but with desktop form factors, this release figures out newer ways to handle text input. It offers features like cancel a keystroke, customizes keystrokes associated with text actions, etc.

  • Automated Scrolling Conduct:

Usually, scrollbars are never seen by default, in iOS and Android apps. For a desktop app, it must occur automatically when the content is huge and hence a widget must be added. For the apt occurrence of the scrollbar, in desktop apps or on mobile apps, this latest release of Flutter has come up with an automated addition of the Scrollbar widget whenever necessary. This helps users to incorporate that feature automatically.

  • Occurrence Of Mouse Cursors Over Text Spans:

Earlier, mouse cursors like hand could be added over widgets. But, if users need to run various text spans with different styles, it was not possible. Now, with Flutter 2.2, users can automatically get the needed mouse cursor, whenever there is a TextSpan with a gesture recognizer.

  • Smoother Page-Transition For iOS:

Through this release, page transition in Cupertino has been made smoother by lessening the time taken for rendering the frames. The development and end-user performance both are sure to improvise. Incremental iOS installs have been implemented which will reduce the time to install and turnaround time to test.

  • Addition Of More Material Icons To Flutter:

There are two different PRs adding new Material icons to this latest version of Flutter, which has an icon for Dash. The desired Material icon can be searched for, through names and categories, in the icons’ library. The addition of Dash to the Flutter app has become much simpler and easier.
