Best Features Of Flutter 2.0 That Boost Mobile App Development

It comes with an updated scrollbar and grabs handle suitable for mouse and touch-based input sequences. We can say that every new addition has been made after due consideration of the usability and utility of the platform application.

Some other functions added to the desktop application development system include the scrollbar widget. This allows users to drag the thumb or use the mouse to move the page up and down. The scrollbars can also be customized according to different themes to make them look better and more presentable.

Finally, within the Flutter new features for Desktop applications, you will find command-line argument handling. This makes it easier and intuitive to find and open files in the application. Flutter 2.0 comes jam-packed with relevant features for Windows and macOS applications.

One thing you will notice down the line is that the resizing of applications meant for desktops has become smoother. With better community support that can help you with native text editing and top-level menu creation, you will find catching up with the new features accessible and possible.

New Features for iOS

Flutter 2.0 brings new Pull Requests (PRs) for iOS application development; these new PRs and other updated functions are added to enhance the quality of applications built for the platform.

Flutter 2.0 brings with it 178 PRs connected to iOS. Some of the major PRs that are a part of the new release include 23495 enabling State Restoration to iOS. Another is 67781 that helps build an IPA from the command line directly without opening Xcode.

In addition to the PRs, you will find a new CupertinoSearchTextField within the system meant for improving the UI of the search bar on iOS devices. Other Cupertino based additions include;

• CupertinoFormSection
• CupertinoFormRow
• CupertinoTextFormFieldRow

These new developmental aspects are added to validate form fields to improve the visual aesthetics of the iOS sections.

While the development work is still in progress, you can expect to observe improvements in the research performance, shaders, and animation aspects of iOS devices.

Added Some New Widgets

Flutter 2.0 comes with a plethora of new features, including widgets, but two of them stand out. The Autocomplete and ScaffoldMessenger widgets are added to improve the development work and increase the speed of creating an application with Flutter.

The AutoCompleteCore widget is about adding minimal functionality to enable the automatic information filling in the application. This feature comes in response to the user’s request about the same.

If you are an avid developer, you will understand the importance of SnackBar in development and how frustrating are the issues arising in the same. The good thing is that the ScaffoldMessenger addresses the SnackBar issues and facilitates different functions related to the same. Some of them are,

• Creating a SnackBar as a response to AppBar action.
• Creating them to work between the Scaffold transitions.
• Showing SnackBars at the end of an asynchronous action.

DevTools is now Flutter DevTools

Flutter DevTools is used for debugging the applications and has become a core of Flutter 2.0 new features. The debugging system provided by this function is added to improve the production quality of the applications built with this technology.

Flutter DevTools lets you come across issues before you have launched the debugging application. This means that the Flutter DevTools runs in the background, checking the codebase as you write and edit.

This zeroing in on the issues works in correspondence with Android Studio, IntelliJ, or Visual Studio Code. Technically, the Flutter DevTools enables these development frameworks to notice these issues and bring them up to the DevTools interface for resolution.

Once the issue is highlighted and displayed on the relevant interface, you can resolve it amicably. Even in modular development aspects, changing one line of code will require changing some other parts of that feature or function.

But with the Flutter new features, you can resolve the code issues while developing. There are some additional innovative features in the revamped DevTools,

1. Error Badges
   When you open the Flutter DevTools interface, you will see the number of errors organized into tabs. This is useful in tracking the specific issues in the codebase.
   
2. Track Image Resolution
   Oversized images slow down the application, which leads to a bad user experience. Flutter DevTools recognizes this and tracks the oversized images that can increase the application size and memory usage. It will inform you about the same so that you can rectify it.
3. Now you can view added average FPS information within the development environment along with recommendations about usability improvements.
4. The memory view charts have been reprogrammed to work faster with a smaller size and easy usability.

Add-to-App

Another one of the innovative features comes in the form of Add-to-App, which allows you to reuse the Flutter code and add it to the existing iOS and Android codebase.

The Add-to-App is compatible with both the mobile platforms and does not change the existing native codebase. The issue with this functionality in the previous version was the problems users faced while integrating the first screen into Flutter.

This issue has been addressed in the Flutter new features. Now the newly added APIs enable the new screen addition in preview on the beta channel. The same are documented on flutter.dev while showing the new patterns.

Flutter Fix

Flutter 2.0 is a future-oriented technology. We say because it has been developed with a future perspective in mind and accommodates the development needs of the future.

Flutter Fix is one of the best examples in this regard. Before understanding what it is, let’s see why Flutter Fix is added to the list of Flutter 2.0 new features.

As any development technology grows and scales, a large number of developers become a part of the community. Due to this, making changes to the frameworks and APIs becomes complex and time-consuming.

There are more than 500,000 developers using Flutter. Imagine the trouble one developer has to go through just because he wants to change one line of code in an API.

Flutter Fix is the answer to the troubles faced by developers in this scenario. Dart fix is a CLI tool of the dart, which helps developers look for the list of deprecated APIs and change, edit, modify, or alter its codebase.

Secondly, Flutter Fix also shows the list of available development fixes that are grouped in Flutter SDK. Lastly, the Flutter Fix also represents an updated group of extensions compatible with Visual Studio Code, IntelliJ, and Android Studio.

This list of Flutter 2.0 new features is not the end of everything new about the updated version of the framework. There are a few more tricks on the sleeve that you will come to know about while developing the applications.

Conclusion

Flutter 2.0 is creating a high-performance application development ecosystem. The developers can build applications for almost every popular platform with a single codebase and let the technology adapt to provide a native-like experience.

We have listed the top Flutter 2.0 new features. Rest assured that there will be new ones coming in the future, and there will be some changes according to the community’s response.

It is important to understand the ways and means of developing an application with Flutter before you begin working with Flutter 2.0. The more you work with this technology and explore its features, the better you will get at building performant applications for every platform.
