Google's Flutter 1.20 stable announced with new features - Navoki

Flutter Google cross-platform UI framework has released a new version 1.20 stable.

Flutter is Google’s UI framework to make apps for Android, iOS, Web, Windows, Mac, Linux, and Fuchsia OS. Since the last 2 years, the flutter Framework has already achieved popularity among mobile developers to develop Android and iOS apps. In the last few releases, Flutter also added the support of making web applications and desktop applications.

Last month they introduced the support of the Linux desktop app that can be distributed through Canonical Snap Store(Snapcraft), this enables the developers to publish there Linux desktop app for their users and publish on Snap Store.  If you want to learn how to Publish Flutter Desktop app in Snap Store that here is the tutorial.

Flutter 1.20 Framework is built on Google’s made Dart programming language that is a cross-platform language providing native performance, new UI widgets, and other more features for the developer usage.

Here are the few key points of this release:

Performance improvements for Flutter and Dart

In this release, they have got multiple performance improvements in the Dart language itself. A new improvement is to reduce the app size in the release versions of the app. Another performance improvement is to reduce junk in the display of app animation by using the warm-up phase.

If your app is junk information during the first run then the Skia Shading Language shader provides for pre-compilation as part of your app’s build. This can speed it up by more than 2x.

Added a better support of mouse cursors for web and desktop flutter app,. Now many widgets will show cursor on top of them or you can specify the type of supported cursor you want.

Autofill for mobile text fields

Autofill was already supported in native applications now its been added to the Flutter SDK. Now prefilled information stored by your OS can be used for autofill in the application. This feature will be available soon on the flutter web.

A new widget for interaction

InteractiveViewer is a new widget design for common interactions in your app like pan, zoom drag and drop for resizing the widget. Informations on this you can check more on this API documentation where you can try this widget on the DartPad. In this release, drag-drop has more features added like you can know precisely where the drop happened and get the position.

Updated Material Slider, RangeSlider, TimePicker, and DatePicker

In this new release, there are many pre-existing widgets that were updated to match the latest material guidelines, these updates include better interaction with Slider and RangeSlider, DatePicker with support for date range and time picker with the new style.

New pubspec.yaml format

Other than these widget updates there is some update within the project also like in pubspec.yaml file format. If you are a flutter plugin publisher then your old pubspec.yaml  is no longer supported to publish a plugin as the older format does not specify for which platform plugin you are making. All existing plugin will continue to work with flutter apps but you should make a plugin update as soon as possible.

Preview of embedded Dart DevTools in Visual Studio Code

Visual Studio code flutter extension got an update in this release. You get a preview of new features where you can analyze that Dev tools in your coding workspace. Enable this feature in your vs code by _dart.previewEmbeddedDevTools_setting. Dart DevTools menu you can choose your favorite page embed on your code workspace.

Network tracking

The updated the Dev tools comes with the network page that enables network profiling. You can track the timings and other information like status and content type of your** network calls** within your app. You can also monitor gRPC traffic.

Generate type-safe platform channels for platform interop

Pigeon is a command-line tool that will generate types of safe platform channels without adding additional dependencies. With this instead of manually matching method strings on platform channel and serializing arguments, you can invoke native class and pass nonprimitive data objects by directly calling the Dartmethod.

There is still a long list of updates in the new version of Flutter 1.2 that we cannot cover in this blog. You can get more details you can visit the official site to know more. Also, you can subscribe to the Navoki newsletter to get updates on these features and upcoming new updates and lessons. In upcoming new versions, we might see more new features and improvements.

You can get more free Flutter tutorials you can follow these courses:

6 Best Weather APIs for Measuring Air Quality Worldwide

Weather APIs, powered by technology, provide weather data (some real-time, some at specific times). These data can influence personal decisions and business decisions. There are also numerous APIs that offer Air Quality information. Each with their own features which makes one better than the other.

Air Quality APIs are used to measure carbon monoxide, air pollution, and air quality index. They help retrieve currently forecasted, and historical data. Individuals and enterprises can then use this data for all sorts of decisions, including travel arrangements or health-related choices.

In this article, we’ll be exploring the best 6 Weather APIs that provide services for measuring Air Quality.

ClimaCell

The ClimaCell Weather API gives real-time and historical information about the weather. The API exposes air quality data, pollen data, and fire index data from all around the world.

With ClimaCell’s Air Quality API, developers can get a good number of useful data which includes health recommendations, percentage of Carbon Monoxide(CO), Nitrogen Dioxide(NO2), and Sulfur Dioxide(S02) in the air, global AQ index, and others.

ClimaCell works by comparing historical air data and real-time data to forecast predictions of the future air condition. This helps in providing the right information and helping businesses make better decisions.

ClimaCell has a free plan which allows developers to make 1,000 calls per day, 100 calls per hour and provides a free sample of the air quality and pollen layer. Other plans support multiple API calls and more features that influence business decisions.

Breezometer

Breezometer is an API service that provides weather data such as wind speed, humidity, precipitation, and air quality with coverage of 95 countries worldwide.

Breezometer has the following features:

1. The data is updated hourly, so you’re sure not to be provided vague or expired data.
2. It provides a 4-day forecast.
3. It provides APIs which range from air pollution to wildfires to pollen reports.

Breezometer offers free and paid plans. While the free plan is limited to 1,000 calls per day, applications using the paid plans can make millions of calls per day and they also get other features like health recommendation, Pollen Counts and Pollen Heatmap.

API Integration Practices and Patterns

We all hear it so often that we almost stop hearing it: “Integration is critical to meeting users’ needs.”

Integration work consumes 50%-80% of the time and budget of digital transformation projects, or building a digital platform, while innovation gets only the leftovers, according to SAP and Salesforce. And as everyone from legacy enterprises to SaaS startups launches new digital products, they all hit a point at which the product cannot unlock more value for users or continue to grow without making integration a feature.

If I were to sum up the one question behind all of the other questions that I hear from customers, enterprises, partners, and developers, it would be something like: “Is integration a differentiator that we should own? Or an undifferentiated but necessary feature that supports what we’re trying to accomplish?”

This Refcard won’t try to answer that question for you. Rather, no matter what type of development work you do, API integration is a fact of life today, like gravity. Why? Today, experience is paramount. The average enterprise uses more than 1,500 cloud applications (with the number growing by 20% each year). Every app needs to integrate with other systems in a fluid and ever-changing application ecosystem. So instead, I’ll share some of the common practices you’re likely to contend with as well as some patterns to consider.

What is Flutter and why you should learn it?

Flutter is an open-source UI toolkit for mobile developers, so they can use it to build native-looking** Android and iOS** applications from the same code base for both platforms. Flutter is also working to make Flutter apps for Web, PWA (progressive Web-App) and Desktop platform (Windows,macOS,Linux).

Flutter was officially released in December 2018. Since then, it has gone a much stronger flutter community.

There has been much increase in flutter developers, flutter packages, youtube tutorials, blogs, flutter examples apps, official and private events, and more. Flutter is now on top software repos based and trending on GitHub.

Flutter meaning?

What is Flutter? this question comes to many new developer’s mind.

Flutter means flying wings quickly, and lightly but obviously, this doesn’t apply in our SDK.

So Flutter was one of the companies that were acquired by **Google **for around $40 million. That company was based on providing gesture detection and recognition from a standard webcam. But later when the Flutter was going to release in alpha version for developer it’s name was Sky, but since Google already owned Flutter name, so they rename it to Flutter.

Where Flutter is used?

Flutter is used in many startup companies nowadays, and even some MNCs are also adopting Flutter as a mobile development framework. Many top famous companies are using their apps in Flutter. Some of them here are

Dream11

NuBank

Reflectly app

Abbey Road Studios

and many more other apps. Mobile development companies also adopted Flutter as a service for their clients. Even I was one of them who developed flutter apps as a freelancer and later as an IT company for mobile apps.
