How is Flutter 2 Better than Flutter 1

How is Flutter 2 Better than Flutter 1

Well, for a relatively short period of time (December 2018 to today), Flutter 1 was victorious in a number of battles, including reduced code development time, a better rendering engine, a faster time to market, and other factors. New applications were developed in the same manner as the one mentioned in the tweet:

In addition, there were some bugs that arose throughout the lifetime of the flutter, which resulted in the creation of the Flutter 2 framework. The date was March 3, 2021, and the developers consider it to be a watershed moment in the development of their property.

All credit goes to Google for hosting an online event to announce the release of Flutter 2. Flutter 2 contains everything that Flutter 1 lacked, and a big Flutter community can attest to this.

It is still possible to improve the performance of Flutter applications, thanks to the addition of Flutter 2. After all, developers will be able to reduce the amount of time they spend writing code for a variety of different operating systems. Flutter 2 makes it easier for users to create the same code on several platforms, including Linux, macOS, Windows, Android, and iOS.

Despite the fact that Flutter 2 has only recently been released, its advantages over Flutter 1 have begun to be recognized and are becoming more well known. After all is said and done, if Flutter 1 served as the foundation for improved app performance among the other dart languages, it also served as a stepping stone to the release of Flutter 2.

In order to better understand the flaws that Flutter 2 is working to overcome, the issues outlined below should be considered.

What are the most significant difficulties encountered with Flutter 1?

The stability, performance, look, and usability of mobile applications are the most important considerations in contemporary mobile app development developments. Flutter developers are therefore unable to fulfill many goals under a single umbrella by utilizing the Dart programming language as a result of this limitation.

Despite the fact that the dart programming language offers parallelism, flexible compilation, rich libraries, and is simple to learn, developers of Flutter 1, in particular, ran into certain difficulties during the development process.

Understand the nature of the Flutter 1 difficulties by looking at them closely:

3rd Party libraries are prone to instabilities:

Despite the fact that it is frequently viewed as a well-maintained and reliable UI framework, there are a number of projects that challenge popular perception. Take, for example, Bluetooth low energy transmissions (BLE).

When you are looking to find a library that can cover the odd circumstances associated with dealing with Bluetooth low energy, you may run into some difficulties in your search.

In your hunt for the most stable library for optimizing the performance of your flutter application, it is likely that you will reduce your search to Flutter blue.

However, if you begin typing–BLE–into the pub. dev, it is possible that it will not appear in the search results at all. On the contrary, it is possible that you will wind up finding it towards the bottom of the list, next to the chaotic and poorly kept analogs.

To resolve this, one option would be for you to copy and paste the string ‘flutter blue’ into Gitlab rather than Github. As a result, some developers may make the mistake of selecting the incorrect library. The fact that a solution is available makes the search process time-consuming and difficult to navigate.


Working with localization has been identified as a challenge by a large number of Flutter developers. Despite the fact that it is possible for developers to determine the locale of any device without any difficulty, the method for dealing with locale-dependent resources is non-existent in the natural environment.

Take, for example, the Android operating system. Android is well-known for employing a systematic approach to resource management. If a developer intends to take advantage of a resource, he or she must do it through code. Furthermore, the resources are organized into distinct folders or subfolders.

When faced with such a situation, developers frequently rely on the widely accepted solution known as JSON files. Although identifying constants as JSON fields may appear to be straightforward when it comes to exporting string constants contained in a straightforward structure in files, it may not provide adequate protection against exceptions during runtime.

Though the Android Studio flutter-i18n plugin can be useful, you may find it problematic when working on a project that does not consist of many IDEs with distinct configurations because it requires the creation of additional files. As a result, when dealing with Flutter 1, localization becomes an issue.

Issues Concerning State Savings:

Do you have any experience with Android?

To refresh your memory, let me bring it back to the thing that you dread the most: the issue of preserving state in an application. If an operating system terminates an application, regardless of whether the state saving type is saved state or orientation state change, the issue becomes tough to manage.

In such a circumstance, Flutter manages the orientation without causing any data loss, but an application that has been terminated by the operating system may not be able to recover the data using the previous session.

Overall, it is reasonable to say that while Flutter is capable of resolving the struggle of orientation state change, it falls short when it comes to state saving in the event that the operating system terminates or suspends the program and the issue remains unsolved.

Adaptive user interface (UI):

A slew of new devices with different screens, pixel densities, and orientations are introduced by firms every year. The list is endless. Despite the fact that it is considered a routine chore, it necessitates significant concentration. Android developers are taught to create UI components for applications that function in conjunction with pixels that are not affected by the density of the screen.

Logic pixels are available in this situation thanks to Flutter 1. According to Google, which is the parent company of Flutter, the UI framework does not have DPS components. However, the logical pixels and the device-independent pixels are of a comparable type to one another.

However, from a practical standpoint, this is not achievable because creating a user interface based on sizes and using the designs may not produce exactly the same results for every screen.

Despite the fact that there are numerous top Flutter advantages, when it comes to the aforementioned features, you should transfer your attention to Flutter 2 in order to increase the efficiency of your Flutter web application.

Flutter 2: What’s New in This Version?

It took Google two years to release an improved version of the software, known as Flutter 2. The revised framework is meant to help developers to create applications that are portable, quick, and visually appealing.

With the release of the Flutter new version upgrade, it will be easier than ever for developers to reuse code to create native apps for the five most popular operating systems: Linux, macOS, Android, Windows, and iOS, among others.

In addition to this, Flutter is compatible with the most popular browsers, including Edge, Safari, Firefox, and Chrome. There’s more to it than that, though.

Flutter 2.0 includes the potential to be incorporated in the Internet of Things applications for automobiles and smart televisions. Overall, the fundamental goal behind the introduction of the Flutter new version upgrade is to place greater emphasis on building an experience for consumers rather than on the platform itself.

Discover what’s new in Flutter 2 by reading on.

Using Flutter 2, it is possible to create a progressive web application.

Following the release of the latest Flutter version, web support has been moved from the beta channel to the stable channel. As a result of this stable release, the reusability of the code that Flutter supported has been elevated to an even greater degree. The web can therefore be supported by developers when they are attempting to build a Flutter application on the platform.

Dart 2.3 was introduced by Google, and it provides solid null safety.

You can’t talk about Dart language without bringing up the subject of Sound null safety. It is used to construct the type system by distinguishing between types that are not nullable and types that are nullable. Because of this, developers can avoid crashes due to null errors.

Using Flutter to create desktop applications

As part of an early release flag for the most recent Flutter release, Google indicated that desktop functionality would be added to the stable channel. In addition, text editing provides a native experience on the platforms that are supported by the software.

Google’s Flutter now has an adaptable user interface (UI) thanks to new features and upgrades.

The most recent Flutter version currently supports the development of apps for three different platforms: Android, iOS, and the web. In addition to this, it is compatible with Linux, macOS, and Microsoft Windows. As a result, the source code can be contracted out to Folio for the purpose of developing an adaptive app.

Flutter SDK is being upgraded.

Due to the fact that the Flutter desktop has been moved to beta, Google has also released a Mobile Ads SDK as a new plugin that provides inline banners as well as native advertisements. This is in addition to the already-existing overlay forms such as rewarded video advertisements, interstitials, and overlay banners.

Flutter 1 and Flutter 2 are two different programs.

As a result of your knowledge of the three different versions of the framework, you should be able to identify a couple of discrepancies between them. While Flutter 1 remained the first UI platform to be released, it provided good computing performance. Flutter 2 introduces several advanced capabilities and solutions to difficulties that had kept developers awake with multiple cups of coffee.

Before we can comprehend how Flutter 2 is superior to Flutter 1, we must first establish a clear distinction between the two UI frameworks.

Web-based assistance

Flutter 1

In the beta version of Flutter 1, web support was provided. Because of this, it was necessary for developers to create various codes for different systems and browsers.


Flutter 2

When it comes to web support, Flutter 2 provides a similar experience on both mobile and web platforms. Because of the mobility of Dart, the flexibility of the Flutter framework, and the power of the web platform, the same code can be used to construct apps for both Android and iOS platforms.


Null Sound Protection

Flutter 1

In the course of designing Flutter apps, developers frequently encountered app crash issues as a result of the null error crashes that occurred. The quality of the apps suffered as a result of this.


Flutter 2 

Sound null safety was added to the Dart programming language by Google. It is possible to distinguish between non-nullable and nullable types as a result of this, which allows developers to spot problems at an earlier point in the development process.

Context Menu that is pre-installed

Flutter 1 

Due to the fact that Flutter 1 did not include a built-in context menu, the developers were forced to wait for a lag before managing touch input.


Flutter 2

Text selection, pivot points, and other core elements such as text selection and pivot points are available through a built-in context menu in Flutter 2. In addition to this, the new Flutter features enable developers to employ a pointing device with high precision for their applications.

Support for the Desktop

Flutter 1 

It was not possible to use Flutter 1 on a PC.

Flutter 2

Google provides a beta version of desktop support in the most recent version of Flutter, which developers can obtain by switching to the beta channel on the Google Developer Console.

Flutter 1

The previous Flutter version had tough time loading advertisements.

Flutter 2 

Google also announced the Google Mobile Ads SDK for Flutter, in addition to moving the Flutter desktop to beta testing status. Developers can use this plugin to run applications that are compatible with the new formats.

UI for the iOS Search Bar

Flutter 1

On iOS, finding a library was a difficult task. As a result, the developers were compelled to go through the lengthy process of finding one.

Flutter 2

Google implemented the iOS search bar UI in response to developer input sent to the company.

Autocomplete and ScaffoldMessenger are two of the widgets available.

Flutter 1 

The existence of such widgets was not present in Flutter 1.

Flutter 2

ScaffoldMessenger and Autocomplete are two new widgets included in the latest release of Flutter 2.

Adding to the App

Flutter 1 is the first of a series of flutters.

It used to be necessary for developers to write separate code for each of the mobile platforms.

Flutter 2

Flutter 2 has been released, and it now allows you to reuse the Flutter code on both the Android and iOS platforms simultaneously.

Predicting the Ionic Framework’s Future Development

Thanks to its powerful HTML5 for native mobile app development utilizing web technologies, the Ionic application, which is written in CSS, Javascript, and HTML, has gained widespread appeal. The Ionic framework places a strong emphasis on visual appeal and user experience, among other things.

Since 2013, the open-source SDK for hybrid application development has been available. At its inception, it was built using Cordova and AngularJS. There are numerous services and tools available for the construction of desktop applications, progressive online apps, and hybrid mobile applications through the framework’s API. In the development of user-friendly apps that demand faster time to market, developers found it easier to adopt Ionic as the platform of choice.

However, in January 2019, Ionic 4 began offering customers the option of selecting their preferred framework from Vue.js, React.js, and Angular.js, which caused some consternation among the development community.

One of the most major disadvantages of adopting Ionic is the performance degradation that occurs during native Android app development. It is possible that the problem might not appear to be significant. When heavy apps employ Ionic, the program is possible to crawl, which is useful for performance reasons. Aside from that, the Ionic framework requires a significant amount of time to transition into live mode, and it does not support hot reloading with live reloading.

Another difficulty that Ionic developers have to deal with is the size of the app. Because of the presence of the plugins–Native Ionic plugins, Capacitor, and Cordova–the mobile application created in the Ionic framework is resource-intensive in nature.

Indeed, the Ionic frameworks provide a number of difficulties, which have forced developers to rethink their approach to app creation in favor of the now-improved version of Flutter.

Despite the fact that the migration has occurred on a large scale, it is not correct to conclude that the Ionic framework has become obsolete. For example, if developers have extensive experience with Angular and web applications in addition to JavaScript and Angular libraries, Ionic is the most appropriate alternative. Shortly said, if you are looking forward to constructing reactive web applications, you can put your trust in Ionic frameworks.

What are the most significant benefits of Flutter 2?

The release of Flutter 2 has barely been a few weeks. Because of this, it is probable that you will be wary of using Flutter 2 for your next project, which is understandable. As a result, it is critical to comprehend the advantages that Flutter 2 brings to the table in terms of Flutter application development.

Discover the most significant advantages of Flutter 2

All platforms use the same business logic and user interface.

Take, for example, any cross-platform framework, which will provide a solution for reusing the codebase across the many platforms that are targeted. Except for Flutter 2, there were no application frameworks that allowed for the reuse of UI code as well as UI until recently.

Time spent on code development has been reduced.

Sometimes it takes a long time to ship the code to the test device when developing an Android application. The hot reload functionality in Flutter 2, on the other hand, allows developers to see the most recent changes without interfering with the present state of the application.

Market entry at a more advantageous period

Developers frequently comment on how much better Flutter 2 performs than the previous version. Because Flutter 2 is compatible with a wide range of operating systems, developers can repurpose code and save a significant amount of time during the app development process.

A more positive user experience

It is widely acknowledged that the user experience provided by Native app development is significantly superior to that provided by hybrid app development. The current version of Flutter 2 includes improved libraries and plugins for improving the performance of hybrid apps as well as native apps.

Developers can experiment with a plethora of functionalities available through Flutter, including Flutter Desktop Embeddings and Flutter for Web.

The most important point is that the Dart programming language has a long way to go

The Dart programming language has been hailed as a well-optimized programming language for macOS, Windows, iOS, and Android platforms, among other platforms. The Dart programming language, which was originally created to compete with JavaScript’s flexibility and web compatibility, has gained popularity at a glacial rate since its introduction.

However, owing to the release of Google’s Flutter SDK, developers can now construct natively built apps, which has helped to promote and spread the programming language throughout the world. Flutter 1 served as a model for the subsequent release of Flutter 2.

In a similar vein, when developers begin using Flutter 2 for both iOS and Android app development, they will be able to identify any gaps, which will then be filled in by the new version.

There is a large Flutter community that is dedicated to utilizing and testing the framework on a regular basis. All things considered, Dart and Flutter combined have a great deal of potential for developers to chart the way for future app development approaches in the future.
