Flutter is the open-source UI development kit developed by Google. It allows you to built an app that can work on both iOS & Android platforms using one codebase and one programming language. With the latest version, it has extended its services to Mac, Windows, Linux & other embedded devices. Flutter 2.0 can also be used for web application development.
Flutter technology has come as a rescue to developers across the world as it is a tedious task to work on different platforms for the same project as the working needs to be changed as per how the operating system adopts it. It is a cross-platform application development that combines the ease of development with native performance while maintaining visual consistency.
What is new in Flutter 2.0?
The most exciting part about Flutter is its support for the web. It has pushed the reusability of code to another level. The approach of flutter is the app-centric framework. It has enhanced the platform capabilities with APIs for building flexible & interactive 2D & 3D graphics.
It has also come up with Canvas Kit-based renderer along with an HTML renderer. It also comes up with a link widget that enables developers to give a web app-like feel in the browser.
Sound Null Safety
It is a remarkable addition to the Dart technology that strengthens the type system by distinguishing nullable types from the non-nullable types. It enables developers to prevent null error crashes which is one of the prime reasons for app crashes. When you incorporate the null checks into the system, these errors will be easily detected during the development reducing the probability of the app crash. It is fully supported in the stable as of Flutter 2, which contains Dart 2.12.
Flutter is also extending its support to desktop applications. You can also build on demand web application which is the current trend. It helps the developers to offer a consistent experience on all kinds of platforms. It includes several important aspects like accurate mouse dragging, text selection pivot points, built-in context menu, etc.
The latest version helps the developers to stop the keyboard events even once they have been initiated. The Reordable Order List helps the developers to move items effortlessly.
The scrollbar widget is updated and another addition that offers top-notch interactiveness in the desktop app as developers can now use their thumb. It also helps developers in the smoother resizing for macOS & Windows.
You can also expect support for various things such as text editing, top-level menus & accessibility support.
Google mobile ads
In addition to Flutter desktop moving to Beta, there is also another exciting addition i.e. open beta for Google Mobile Ads SDK for Flutter. It is a brand new plugin that supports loading & displaying banner interstitial (full screen), advertisements & rewarded video ads. Also, it supports Ad Manager & Admob so no matter what size publisher you are, this plugin can be customized according to your needs.
Platform adaptive ad
The developers usually face issues and write an application that can adapt itself to different screens such as small, medium & large. There are other factors such as different modes (mobile, web & desktop) and input modes (keyboard, mouse & touch).
Latest iOS features
Flutter with the 2.0 version is focusing on strengthening iOS support with the latest features. 178 PRs are iOS related including 23495 that brings State Restoration to iOS, 67781, which fulfills a long-standing request to build an IPA directly from the command line without opening Xcode, and 69809, which updates the CocoaPods version to match the latest tooling.
Autocomplete & ScaffoldMessenger
With the latest update, the developers can access the new widgets- Autocomplete & ScaffoldMessenger.
The Autocomplete feature allows inducing auto-complete features in your apps that are built using Flutter. Autocomplete core represents the minimum functionality that is required to get auto-complete functionality into your flutter app.
ScaffoldMessenger helps in the easy creation of SnackBar for the action between the Scaffold transitions.
Additional instances with Add-to-App
Flutter has become a popular choice for many developers as it enables them to reuse the same code for developing mobile applications for both Android & iOS. Further, you can add flutter to an existing application App-to-App feature. It is crucial because it saves the native code base and helps the developers to execute the code on both platforms.
The new Flutter DevTool enables Visual Studio Code, IntelliJ & Android Studio to help developers with debugging & checking if there are any exceptions. It also can identify images that have a higher resolution.
