Read ahead to find out.

What was Flutter 1.0 Capable of doing?

Flutter 1.0 was basically Google’s open-source framework that is used to build Android and iOS applications. However, the open-source framework was unable to run on desktop, mobile devices, and embedded systems. Later on, Google recognized the issue and updated the framework by adding more features on the web and mobile, and with further updates, Flutter 1.0 was capable of;

• 2D dimensions to create vector animations.
• Increased Dart 2.1 speed and flexibility
• Powerful composition capabilities
• Leveraging Dart 2.1 version, flutter provided faster type checks and smaller code size.
• Offering pixel-perfect experience along with a comprehensive set of widgets.

What has evolved with the release of Flutter 2.0?

Do you know;

Just by switching to Flutter framework, Google Pay’s mobile app developers were able to eliminate 50% of their code from the codebase – making the app lighter, efficient and faster?

Compared to Flutter 1.0, Flutter 2.0 is a more versatile and efficient framework to build fast, portable and beautiful applications for the innumerable operating system including Linux, macOS, Android, iOS, and Windows. It now operates on multiple web browsers including Firefox, Safari, Chrome, and Edge.

Achieving huge achievement in Flutter 1.0, flutter app developers were eagerly waiting for the stable release of the UI toolkit. Its single codebase allows you to make multiple applications. Be it smart homes, televisions, or cars, Flutter can be used to build complex and integrated applications.

Uplifting platform restrictions, Flutter 2.0 has become a portable framework to unleash its full potential.

In the Words of Google,

“Our goal is to fundamentally shift how developers think about building apps, starting not with the platform you’re targeting but rather with the experience you want to create. Flutter allows you to handcraft beautiful experiences where your brand and design come to the forefront. Flutter is fast, compiling your source to machine code, but thanks to our support for stateful hot reload, you still get the productivity of interpreted environments, allowing you to make changes while your app is running and see the results immediately.”

What’s new with Flutter 2.0?

1. Flutter for Web

Flutter has faced a few obstacles to the web. In order to create a responsive user experience, widgets need to be developed. Some additional functionality needs to be implemented like hover to enable a smooth user experience. Dart was originally meant to replace JavaScript and instead, the dart2js compiler has been used widely.

Since the web is a tricky platform to deal with, Flutter 2.0 is now a part of the stable channel. It simply means that the beta version is no longer available and we’ve the stable version which focuses solely on performance and render fidelity. Flutter now consists of rich platform APIs with 2D and 3D graphics and a flexible layout.

2. Acknowledgment of Web Performance

3. Sound Null Safety

Sound Null Safety – One of the most notable additions to the Dart language. This feature allows developers to identify between nullable types and non-nullable types. This helps developers to prevent null error crashes during the development period.

By default, the non-nullable type is checked true which enables static checks and compiler optimizations to assure that null-dereference errors won’t happen at runtime as they will be spotter earlier when the app is getting compiled and will be fixed too.

4. Flutter for Desktop

This is indeed one of the major changes introduced with Flutter 2.0. The desktop status is now stable as compared to the previous version in the Alpha stage.

Flutter app development for Desktop now also supports keyboard shortcuts that leverage the feel of using Native applications of Linux, Windows, or macOS. It’s an important change from the user’s perspective. So, whether they’re using a mobile, laptop, or browse windows, the web experience will remain consistent. It also offers interactive scrollbars too.

You know what’s the best part of Flutter 2.0? It triggers a wide range of use cases. modern world. Flutter 2.0 can make the world smarter by getting embedded in cars, smart Tvs and home appliances.

5. Web App Features & Widgets

6. Flutter for Mobile – Foldable device

The latest feature of a mobile app to hit the market is termed “foldable phones”. Such phones not only allow users to run applications on two screens but also help them make use of tool screen design patterns like two page, dual view, list-details, companion pane, and extended canvas. Such a feature is introduced so as to boost productivity while working on the device.

Flutter 1.0 didn’t accommodate foldable displays but Flutter 2.0 does. This way, developers can take advantage of dual-screen devices or foldable phones to build apps regardless of the platform selection.

7. Google Mobile Ads

The latest Flutter 2.0 has introduced us to the Google Mobile Ads SDK beta version.

So, what can be expected with this Mobile Ad beta version?

The beta version ( which is still in validation mode) will aid developers to indulge native ads and inline banners in the pre-existing overlay formats. It will allow developers to easily customize advertisements using Admob and Ad Manager.

8. Platform Adaptive apps

Though Flutter now supports multiple operating systems including Linux and macOS,

Still, developers are often wondering;

How to write an app that works seamlessly across screen sizes – Small, medium, or large?

Last but not least: How much does it cost to build a flutter app in 2022?

Well, flutter app development is a complex and diversified process that is influenced by multiple factors which makes it difficult to estimate rates.

However, considering the common rate standards, Indian companies leverage the cheapest solution starting from $10/hour. If we consider American or Canadian-based companies, these agencies charge hourly rates up to $150-$200 per hour. Talking about the European companies, they aren’t homogeneous. Western European companies charge somewhere between $100 to $150 per hour while eastern European companies charge around $25 to $50 per hour.

As per my opinion, Flutter being an open-source technology, a lot of free resources are available to use which reduces operational expenses to a great extent. It eliminates the need to buy licensed tools too which is an expensive affair. So, whenever you think of hiring a flutter app developer, prices can be even lower. And, this makes Flutter even more advantageous.
