Ddos 
The framework has phenomenal documentation, written with a lot of love. It can be read like a book. By following the links and anchors back and forth, you will gradually learn everything you need to get started. There is even a Cookbook with specific examples: work with the network, send a request to the server, download a picture, show it, work with GPS, with a camera, and so on – everything is described in detail. Nowadays flutter app development is at the center of the attention of many developers.
Why flutter is gaining popularity?
Flutter has a public repository of libraries, and the community is actively using it. If you can’t find a suitable package there, then it simply isn’t there.
Dozens of new libraries of various quality appear there every day. To separate the wheat from the chaff, Google introduced two certification programs.
Trusted Authors Certification – Applicants meet a number of requirements, are screened, and marked in their profile. Most probably flutter app development would become more and more popular.
The badge for the best libraries is an award for quality material, a kind of state of art. Libraries are evaluated according to a large checklist, the author must have the status of a trusted developer.
The repository contains about 15-20 thousand libraries, and there are a lot of trusted authors. But the best libraries are about 15 for the whole pub.
Trends in flutter app development:
Efficient code writing and app testing
Flutter is extremely mature and is used by major Google applications like Adwords. There are the code formatting features, which are built into editors. With the help of them can’t be formatted Dart code in an efficient way. In its turn dartfmt is a code formatter, which is a part of the Dart SDK. The code can be formatted according to the Dart code specifications. Those developers who choose this variant state that it’s rather efficient. That’s why the perspectives of its use are rather clear.
Allows developers to create apps for both platforms
Flutter is a new and promising platform for writing flutter mobile app for Android and iOS, as well as Web applications. At the webinar, we will look at the capabilities of this framework and write a simple application for Android + Web. Most Flutter apps exist on iOS and Android devices, which means their performance has to be balanced against the low power consumption of mobile processors and short battery life. At the same time, both Google and Apple insist on smooth and fluid interfaces, as well as a lot of animation. The result requires very careful balancing and makes code optimization a key skill.
Saves A Lot Of Time For Everyone
Flutter is brand new – the SDK even comes with its own programming language called Dart. And the relative newness does indeed level the playing field between developers with different backgrounds in the past.
Same UI and business logic in all platforms
Code doesn’t exist in a vacuum. Even if it works right now with Swift app development, things could change in the future. And if the code is convoluted like noodles and no one knows how its functions work, then you won’t be able to easily maintain or update it. Therefore, being able to write readable, well-documented code is essential for any developer.
Utilization of widgets
In the application interface, the widgets are very important. As for Flutter mobile apps. There is provided a great UI experience. And the comparison can be done to any other framework of a cross-platform type.
