New features in flutter 3

Almost a month after Flutter announced that it would be launching on Windows, it has already released its newest version.

This updated version is reliable on both macOS and Linux, and it supports Apple Silicon. The transition from Flutter 2 to Flutter 3 bridges the gap between a mobile-centric and a cross-platform framework.

Natively built apps may now be created using Flutter, the most popular and widely used cross-platform UI toolkit.

The wonderful part about the new features in Flutter 3 is that it allows everyone to take advantage of its immense capability. There are countless ways to unleash the potential of this open-source platform.

Flutter 3: Overview

Flutter 3 enables the creation of avant-garde experiences across six platforms from a single codebase, freeing up developers’ time to focus on other tasks and enabling entrepreneurs to present new concepts to the whole addressable market.

Previously, Flutter supported iOS and Android, as well as web and Windows, but with the release of Flutter 3, Google has added solid support for macOS and Linux.

The goal is to provide developers the freedom to take advantage of the full power of the underlying infrastructure while exchanging as much of the UI and functionality as they desire.

Apple’s silicon chips and Intel’s processors can now run Flutter apps at full speed thanks to the new Universal Binaries feature in Flutter 3. Google and Ubuntu’s Canonical have worked on the Linux version to give Flutter app development company, a highly integrated alternative for application development.

Advantages of Flutter for Developers

Hot Reload

Usually, iOS and Android developers must generate code, and then wait for it to be compiled and deployed on the device before noticing any alterations.

Flutter’s hot reload, on the other hand, allows developers to see the results of their changes right away.

Advantages of Flutter for Developers

As a result, your development team and QA engineers can work together more efficiently, make rapid adjustments, and see the outcomes right away. This is exactly why any mobile app development company prefers Flutter over other frameworks.

Instantly Deployable Widgets

A customizable widget kit makes it simple to build apps of any complexity level. Widgets are quick, dependable, and expandable on any screen size.

Moreover, a significant number of Material and Cupertino widgets are available. Graphics and gesture processing may also be done in a flexible manner. As a result, the entire process is streamlined and expedited.

Extensive Community Support

Flutter is created by Google, and the tech giant frequently updates and fixes issues for Flutter developers. In addition, the performance of Flutter is noticeably better than that of other technologies, such as Node.js or Java.

It’s easy for both experienced developers and newbies to learn from one another because of the welcoming development community.

Also, Google hosts a number of events for both startups and existing organizations to meet, talk, or learn about how the Flutter app might aid in the growth of their respective companies.

Going Beyond The Mobile

Many developers are already taking advantage of this by creating Flutter applications that function across multiple platforms, including the web, pc, and even television.

Despite the fact that these features are at various stages of development, Google has the ability to provide a stable release.

For now, it seems probable that the business will continue to focus on IoT development using Flutter.

Improved Speed of Time-to-Market

Flutter is a more efficient development platform than its competitors. In the majority of circumstances, developing a Flutter app will need 2 hours less as compared to developing the identical software individually for Android and iOS.

The key reason for this is that no platform-specific code is required to get the correct aesthetics in your app.

Flutter can implement any 2D UI without the need for a native app equivalent. It also has a declarative API for designing UIs, which improves efficiency substantially.

Own Engine for Rendering

Unlike other platforms, Flutter lets you accomplish so many things with your applications that aren’t possible. Obviously, this necessitates a very robust structure.

In reality, the vast majority of what has been discussed so far would be impossible without a powerful cross-platform rendering engine.

Skia is used by Flutter to render itself onto a canvas given by the platform. It is possible to deploy Flutter-built user interfaces across a wide range of platforms due to the engine.

In other words, you don’t have to make any changes to the UI to make it work on a new platform, which streamlines the project development.

Implementation of Simple Platform-Specific Logic

Sophisticated OS features, such as GPS location, Bluetooth, sensor data collection, and permission handling, are critical to many real-world mobile apps.

Many of these may be found in a ready-to-use plugin provided by Google when creating a Flutter app.

However, there may be situations when the app relies on an OS-level capability that is currently unavailable as a plugin.

But don’t worry, the crew has your back here, too! If you’re looking for a mechanism to communicate between native code and Dart, Flutter is an excellent choice.

As a result of this, Flutter apps can accomplish whatever a native app can do with only a little more work on the native side.

Native App Like Performance

User experience (UX) relies heavily on the performance of an application. In most circumstances, the performance of a Flutter application will be similar to the performance of a native app, and even better in complicated UI animation scenarios, than the performance of a native app.

As opposed to other cross-platform frameworks, Flutter uses no intermediary representations or interpretations of the source code to accomplish its objectives.

There are no flaws in the interpretation process because Flutter is incorporated directly into the machine code.


Every organization has a primary objective of reducing costs. When designing native apps, businesses must pay for both the iOS and the Android versions at the same time, which can be costly. With two different teams, they have to split the funds 50/50.

Flutter’s functionality allows you to create and manage your apps with only one Flutter development team. A large amount of time and money may be saved as a result of this method of development.

What’s New in Flutter 3: Top New Features

System Menu Bar Support with Menu Cascading for MacOS

It is now possible to develop platform-specific integration into Flutter 3 by using additional inputs such as platform-specific interactive models for development.

New Features of Flutter 3

The update’s goal is to provide users with more control over how the operating system is used and to share the best user interface and logic available, depending on the situation.

Flutter’s most recent developments focus on platform support rather than pixel rendering.

Support for Material Design 3

Using Flutter 3, you may make use of the new Material Design 3 features. As part of Flutter 3, Android 12’s Material You features, such as dynamic color and a refreshed color system as well as new visual effects like ripple design, may be enabled via an opt-in option.

Flutter Firebase

Publishers of Flutter apps need a full collection of tools to operate, produce, and release the applications. Some examples of these include cloud-based services for storing and authenticating data as well as evaluating hardware.

Firebase, AppWrite, and AWS Amplify are just some of the third-party connectors that Flutter has. Firebase is Google’s back-end platform for developing mobile and online applications.

A new feature of Firebase’s core product, Flutter Firebase integration, has been made available by the Flutter team. A Slashdata survey found that 62% of Flutter app developers utilize Firebase to host their Flutter apps.

The Flutter Crashlytics plugin now offers the same set of functionality as Firebase’s well-known real-time error reporting service for tracking real-time fatal failures.

App stability indicators like “crash-free users” are included in the features to help you monitor the health of your application.

The Crashlytics pipeline has been improved to better the grouping of Flutter crashes, making it easier to evaluate, prioritize, and address problems.

Toolset for Flutter-Based Casual Games

It’s great news for game designers! It’s not just apps that are benefiting from Flutter; games are already in the works.

The casual game toolkit from Google is a collection of templates, regulations, and tutorials aimed at helping game creators get started with Flutter. Prior to Google’s latest announcement, Flutter’s only focus was on the applications and their functionality.

Flutter has been used in a number of popular video games. To learn more about how Flutter is used in games, game developers can explore the flame gaming engine.

Linux and Mac OS X Support

When Flutter was first launched, it was well-received by the development community. To date, Flutter has been regarded as the most innovative cross-platform development framework on the market.

The framework may now be used to develop programs for Windows, Android, and iOS as well.

When Flutter 3 was released, the developers who had been undertaking the work of bringing in new platforms were no longer needed. Right now, Flutter developers may design applications for both Mac OS X and Linux devices without any issues.

Dart 2.17

The Dart SDK has been updated to version 2.17 with the current release of Flutter, which also includes an upgrade to the language version of Flutter itself.

Developers may expand enums and alter their default functions in Dart 2.17, which is one of the most notable features of the language. This gives enums the ability to behave very similarly to custom-written classes.

Features of Flutter 3 of Web and Mobile

Support for Dynamic Refresh Rate

When it comes to iOS devices, the latest Flutter version includes support for ProMotion screens and variable refresh rates, including those seen on the iPad Pro and iPhone 13 Pro.

Web and Mobile Features in Flutter 3

Up until recently, the rendering capacity was restricted to 60 Hz frame rates. The user may enjoy a more fluid scrolling experience while seeing rapid animations.

Support for Foldable Phones

Together with Microsoft, Flutter 3 will enable support for foldable mobile devices as well. Incorporating these new functionalities into foldable devices would provide developers with a more dynamic and productive experience.

Intensely Faster iOS Releases

Flutter 3 introduces a new feature that allows developers to construct an IPA command that may be used to launch any iOS app more quickly.

Decoding Images

Flutter 3’s new APIs allow you to decode pictures asynchronously off the main thread. This is done using the browser’s built-in image encoder.

Using this feature, the decoding of the picture is twice as fast, guaranteeing that the mainstream is never stopped and eliminating the trash that has built up in the past.

Lifecycle of a Web App

Your app’s bootstrapping procedure may now be fully customized thanks to the new Flutter web app lifecycle API! The app may now take advantage of desktop support.

Flutter 3 – Performance Enhancements

Using benchmarking, the Flutter engineering team has brought the increase in performance to a new level. Improved opacity animation performance is the most significant improvement.

Opacity, for example, does not use the save layer function when an Opacity widget only has a single drawing primitive. 

Predicting and estimating the complexity of the rendering picture is one of the new features of Flutter 3’s release. This technique is used to minimize memory consumption without affecting the performance of Flutter apps.

Extensions for Themes

All of the material library’s ThemeData may now be customized by adding custom extensions to the ThemeData file.

ThemeData.extensions can be used instead of extending ThemeData and re-implementing copyright, lerp, and other methods. Furthermore, you may supply ThemeExtensions as a package developer.

In-App Advertising on Android

An improved speed in user-critical activities like scrolling and page transitions should be expected when you utilize the Google mobile ads package

This is especially evident in gadgets favored in emerging markets. There are no code modifications necessary, which is the greatest part!

Flutter now assembles Android views, also known as platform views, in a synchronous manner behind the scenes. As a result, the Flutter raster thread doesn’t have to depend on the Android view to render before it can start drawing.

As an alternative, the Flutter engine uses an OpenGL texture to display the view on the screen.
