Flutter: the framework for cross-platform applications – Bollywood Siyappa

Must read


One language that I’m sure everyone has heard of is flutter.

A language based on darts is called Flutter. It is a cross-platform application framework powered by Google that makes our work more efficient and produces the desired outcome.

Does Flutter increase developer output?

The Flutter team still conducts a quarterly user survey to get input from you, our Flutter developers. The first survey of 2022 was available between February 22 and March 3 on Twitter, the docs.flutter.dev website, and the Flutter IDE plugins, and it attracted over 8000 responses.

Flutter continues to receive the highest number of “very satisfied” reviews in history (60%) and is remains incredibly popular with developers (93 percent are satisfied). This is significant since, according to the poll, there are now more Flutter developers than there were in the previous quarter (from November 2021 to February 2022). We’re happy to see that despite the community’s growth, Flutter is still delivering high levels of satisfaction.

We value your support and are constantly on the lookout for cues that point out areas in which we may improve. Although there is always space for improvement, we want to share with you what we’ve discovered and how it has shaped our roadmap.

Tool Dart

The language is simple to use thanks to the Dart analyzer, compiler, DevTools, and IDE plugins. Several developers informed us that when the Flutter project is huge, Dart tools might become slow or even unresponsive. In our upcoming poll, we aim to determine how common and serious this issue is.

We discovered from our poll that about a quarter of developers (24.5%) had encountered this symptom, and nearly half of them claimed that it had a very bad (16.7%) or moderately negative (29.6%) influence on work.

We anticipated these numbers to be lower, and we’re keen to make improvements in this area, so we want to get in touch with a few developers who indicated an interest in having a follow-up chat to reproduce the issue and ultimately enhance the functionality of the tools.

Flutter’s value to developers

With its Flutter framework, developers can create stunning, quick, multi-platform applications from a single codebase. We investigated whether these values have been upheld by Flutter developers in this survey.

Both those who converted existing apps to Flutter and those who built a new Flutter app from scratch were subjected to separate questions. When multiple responses were permitted, 59.2 percent of respondents said they had started from scratch and 26.5 percent said they had converted or added Flutter components to an existing program.

We polled those who used Flutter to build a new app on their level of agreement with three claims about target platforms, development efficiency, and interaction with other Google services. When compared to alternative technologies, we discovered that over 90% of them agreed that “Flutter reduced time to design and publish new apps” (92.1%) and that “Flutter enabled my product to target additional platforms.” 92.2 percent

The same inquiries were made of people who used Flutter for already-existing apps. 85.3 percent of respondents and 90.7 percent, respectively, agreed that “Flutter enabled my app to be produced more quickly than before” and “Flutter enabled my app to be offered on more platforms than before.” Another 84.8% of developers agreed that “Flutter made my app look more lovely than before,” another finding.

Undoubtedly, we heard what Flutter should do better, such as offering more plugins for all platforms it supports, increasing the amount of documentation it has, enhancing performance as perceived by users, better integrating with other tools, etc. It was also mentioned in some remarks that despite repeated surveys over the years, some problem areas remained the same. We appreciate your patience as we work to fix the problems and enhance the product. The fact that our developers are more effectively aiming for more platforms is something we are happy to discover and share.

The development of a mobile app can be expensive. Performance standards for mobile apps have risen sharply in recent years, but they aren’t necessarily affordable or simple to achieve. Mobile teams looking to stretch their budget may feel relieved by resources like free crash reporting SDKs. But occasionally, free software can turn out to be considerably more expensive than commercial options.

In this article, we’ll look at what it means for commercial software to be free and analyze its components concerning cost and risk. All of this isn’t to say that free can’t be useful when developing a mobile app. But before agreeing to those terms and conditions, it’s crucial to understand how much your business could wind up paying.

Flutter’s add-to-app functionality is an excellent place to start if you’ve ever wanted to test it but don’t want to build something from scratch. To demonstrate how seamlessly Flutter can be incorporated into a native codebase, we collaborated with the Flutter team to develop an example add-to-app prototype. This will make it even simpler for you to put Flutter to work for you. Whether you want to test out Flutter or demonstrate to your team how it functions, this article is for you!

Flutter integration with Angular on the web

Within the native web app, the Flutter module operates as an iframe. Run a Flutter build for the web target before adding the feature to the Angular codebase. In this phase, an index.html and other required files are created. In the Angular app’s src folder, move all of the build files. From there, you may refer to the build files included within the iframe. You’ll be able to use the Flutter functionality after restarting the web app.

Kotlin’s edition of Flutter to Android

Let’s now include the NPS module in the Android application. First, launch a cached engine-based Flutter activity. The Flutter engine starts warming up as soon as you open the native news app. You will then launch a new activity and direct it toward the Flutter activity. This guarantees a speedy conversion from native Kotlin code to Flutter and enables the Flutter feature to operate without interruption inside the Android app.

With SwiftUI, Flutter may be added to iOS.

Finally, the iOS App can include the NPS Module. In Xcode’s build settings, first, add the compiled Flutter module to your application. The Flutter engine should then be started and created as an instance in your application delegate. Once that is finished, you may deliver Flutter UI wherever it is required by simply building a Flutter ViewController with the Flutter Engine. Run the flutter build ios-framework command after that.


Animations, For instance, you may modify the AnimatedContainer widget’s attributes by changing the animation’s duration, the container’s height, its shape, and its color.

There is a unique page animation transition in the NPS module. Another example of an animation that can be modified by changing its duration and other components is the SlideTransition widget.

You could import the animation package from the pub. dev and use some of the elaborate, pre-built animations to advance your animations.


The NPS module’s theme can also be easily updated. You can easily adjust the colors, button style, and font all in one location because it makes use of the built-in Material theming via ThemeData. Use the given Material color palette shades or your custom colors to update the accent color and background color of the NPS module, for instance, to your desired hue.

Added characteristics

The user’s score reaction is tracked by the Flutter NPS module using flutter block state management. When developing Flutter applications, there are numerous solutions for state management, including Cubit. Additionally, the feature offers widget and unit tests, which are helpful resources to make sure the code you’re building is operating as intended. The source also includes native localization support for 78 different languages. Before merging changes, this project can perform formatting, lifting, and testing phases through continuous integration using GitHub Actions.


Even though this prototype does not presently communicate with a backend, you might set it to do so to save the NPS module’s data or even to fetch sample articles for the native newsfeed. Firebase, which effortlessly integrates with Flutter, is one possibility to consider. To add Firebase to your Flutter app, consult the Firebase documentation.

You could use a similar procedure to include a Flutter feature into any native app now that you understand how to add one to a native web, Android, or iOS codebase.

supporting multiple platforms.

You can see how the NPS module handles platform variations by supporting multiple platforms. The module responds to input from a mouse or screen reader when used online and shows it as a dialog on top of the newsfeed. When used on a mobile device, the module fills the entire screen and responds to touch or screen reader input.

Be aware that the Flutter NPS module includes material widgets, which, depending on the user’s device, perform gesture detection automatically. The program accepts touch input when using a mobile device and mouse input when using a desktop device.
