A grand and landmark launch, Flutter 2.0 consists of a lot of patches and features that make this platform a preferred framework option for developers to create robust cross-platform apps.

Around the globe, mobile app development organizations use Flutter for developing iOS and Android apps, but the most recent Flutter 2.0 empowers developers to create customized apps for various platforms including Linux, Windows, Mac, and embedded devices. A cherry on top is that the new version enables developers to innovate using customized web apps that can be used on the browser.

The framework has resolved more than twenty-four thousand problems by merging over seventeen thousand PRs from approximately 765 contributors and Flutter 2.0 is a stable version. All in all, the latest version possesses several new features to offer while ensuring a flawless performance for cross-platform apps.

Premium Features and Performance Updates in Flutter 2


The new version of Flutter and we present the major features and improvements from the app development company’s viewpoint. Let’s begin with the biggest update.

Flutter Web

Amongst several exciting things happening as part of Flutter 2, Flutter web is one of the most beneficial and stable milestones. Alongside the launch of Flutter 2.0, the platform’s web support has switched from beta to stable channel. Assistance through the web platform has given rise to a new era of app development using Flutter as the reusability of the code has gone to a new level. Flutter app developers can utilize the web platform to develop a stable app.

By the introduction of web support, Flutter has facilitated developers to seek the benefits of a web platform and simultaneously build f32 rich and interactive web apps. The focal point of Flutter app developers revolves around app performance and improvements to rendering fidelity. The updated version has the capability to support a new CanvasKit-based renderer in addition to the existing HTML renderer. additionally, web-specific features including Link Widget make sure that your app running in the browser feels like a web application. However, there are some web design and development tools and tips that you can follow and use for your development.

Sound Null Safety

An essential addition to the Dart language for strengthening the type system. Such an element can differentiate nullable types from non-nullable types. It provides a way for developers to readily prevent null error crashes resulting in the prevention of app crashes. The users amalgamate null checks into the type system to catch errors during the development process itself which inherently prevents crashes in the final stage. Flutter 2 completely supports sound null safety. There are over 1000 null safe packages published in the pub.dev package repository.

Desktop support

Akin to the web support, Flutter 2.0 brings enhanced desktop support in the stable channel along with an early release flag. Flutter developers can give desktop support a shot for launching Flutter apps. One may consider this as a “beta snapshot” of the upcoming final stable release in the latter part of 2021.

Flutter development is greatly enabled by the 2.0 update to stop the keyboard-based events even if they have been initiated. The developers may also move several items in the ReorderableListView widget with ease. Flutter 2.0 has an updated scrollbar widget to facilitate superior interactiveness in the desktop app, and developers can scroll the page up and down using their thumbs.

Flutter development can also include customization of the Scrollbar. The developers can align the scrollbar with the app’s look and feel with the new ScrollbarTheme class for true specificity and customization. A grab handle is also available for mouse or touch input. The desktop-based Flutter app displays pages and down tracks. It is also possible to resize Flutter apps for macOS and Windows using a new version.

Another feature, a built-in context menu has been included in the TextField and TextFormField widgets for Material and Cupertino designs for Android and iOS respectively. The always enthusiastic and thriving Flutter community backs several things including native-like text editing, accessibility, and native top-level menus. What’s more, Flutter developers have included command-line argument handling for Flutter apps so that easy tasks like a double-click on the data file in Windows may be used to open the file in the Flutter app.

Adaptive cross-Platform Apps

This app development supports Linux, macOS, and Windows in this updated version. Flutter 2 also supports Android, iOS, and web platforms. Hence, a query arises in the mind of various developers regarding the writing of an application that acts as a versatile platform to different sizes of screens, mediums, devices, and input modes. An appropriate answer to this question can be given through a folio app. It is defined as a straightforward app that can operate properly on a multitude of platforms with a single code base. These apps act as an example of “platform adaptive” because it adapts well to any platform.

Enhanced iOS Features

The latest release of Flutter consists of extended support for iOS through 178 PRs merged, with 23495 that brings State Restoration to 67781 iOS and empowers developers to construct an IPA directly without starting Xcode. Along with this, the CocoaPods version is upgraded by 69809 to be coherent with the latest tooling. CupertinoSearchTextField presents a UI for the iOS search bar. Certain other widgets including CupertinoFormRow, CupertinoFormSection, and CupertinoTextFormFieldRow may help developers create valid form fields in line with the visual aesthetics of iOS.

Google Mobile Ads SDK

The new features also include the Google Mobile Ads SDK beta version. This aids developers to add native ads and inline banners with the present overlay formats. A Flutter app development company can readily customize advertisements with the aid of Admob and Ad Manager.

Flutter Dev Tools

Lastly, the Flutter 2.0 release has modified the community’s name to FlutterDevTools from DevTools to FlutterDevTools especially for debugging. This latest version of FlutterDevTool enables Visual Studio Code, IntelliJ, and AndroidStudio to help app developers with debugging by checking for exceptions. Additionally, the new FlutterDevTool is capable of identifying high-resolution images with utter ease.

Parting Thoughts

There is no denying the fact that Flutter is a robust cross-platform app development framework. Each release and updated version of Flutter presents new horizons of opportunities for dedicated developers. The new Flutter 2.0 update has put forth many fascinating changes and performance improvements for the community.
