Simple & Lightweight

Highly Testable

For Dart, Flutter, and AngularDarttest flutter dart

Today I'm publishing a new video covering the fundamental features of the Dart language, and showing how to use them in practice.

Using them correctly leads to code that is clear, lightweight, and more robust.

This is a fast-paced and focused video, and I hope you like this new format.dart

At times you will have to make your Flutter app support different language or “locale” or in other words make your app Internationalized. Flutter provides widgets & classes that help with this and the Flutter libraries themselves are internationalized. In the following tutorials we’ll use the APIs and tools provided by the intl package. If you’re new Dart’s intl package, i suggest you have a look at the Dart intl tools.

As you might know Flutter is now taking over vast majority of market, so if you’re a software developer there is 99.9% chance that you will come across this. So here’s an easy step by step tutorial for internationalization of your flutter app, also we’ll see how to manually switch your App’s Locale on specific events. I’ll assume you know how to setup a flutter app so we’ll skip that part. Alrighty then Avengers! Assemble!!flutter dart

Recently Google released the technical preview of Flutter Web, an extension to Flutter for the modern web. So what does this mean? It means that now it’s possible to have one single code base for Android, iOS and the Web. Since Flutter is built using Dart, which includes production-quality compilers for both native machine code and JavaScript, web support was just a matter of time.javascript unity flutter dart

State management is a hot topic in Flutter right now.

Over the last year, various state management techniques were proposed.

The Flutter team and community have not (yet) settled on a single “go-to” solution.

This makes sense, because different apps have different requirements. And choosing the most appropriate technique depends on what we’re trying to build.

Truth be told, some state management techniques have proven very popular.

• Scoped Model is known for its simplicity.
• BLoCs are also widely used, and they work well with Streams and RxDart for more complex apps.
• Most recently at Google I/O, the Flutter team showed us how to use the Provider package and ChangeNotifier to propagate state changes across widgets.

Having multiple choices can be a good thing.

But it can also be confusing. And choosing a technique that will work and scale well as our apps grow is important.unity flutter dart

A stream is one of the challenging topics for the beginner. It took lots of efforts to understand. In order to understand the Streams, you will need to go through the various Examples and then you will get what Exactly Streams is.

At the end of the post, I will write one Flutter application which will be based on the same example which I had discussed in Dart.

I am also going to put my understanding of Streams into the words and Examples.unity flutter dart

Today we’re announcing the stable release of the Dart 2.3 SDK, with new language features that improve your coding experience when developing user interfaces, new tooling support for developing Flutter UI, and two new websites: dart.dev & pub.dev.flutter dart

There’s always some small detail in every programming language or framework that once discovered, makes it a lot easier to work with.

This article is all about the Dart and Flutter tips, I will be writing an article like this every month. My aim is to cover all the Flutter and Dart Tips I have discovered. All tips shared can be found in thus “FlutterDartTips” repo on Github.flutter dart

Hello again! Have you already heard about reactive programming? RxDart is a reactive functional programming library for Dart language, based on ReactiveX. Dart already has a decent package to work with Streams, but RxDart comes to adds functionality on top of it. But now you might be asking, what’s Stream?react flutter dart

One of the features of Flutter is a possibility to create apps in record time. However, it is very important to write Dart code properly and to use the best practices, Effective Dart, from the beginning. There are some good tools and packages that help you to apply best practices quickly.perl flutter dart

I have been learning mobile development with Flutter for a while and throughout my journey, I have learned how to manage the state using the BLoC pattern and RxDart.flutter dart

If you're familiar with object-oriented programming concepts, you should be able to complete this codelab. You don't need previous experience with Dart, mobile programming, or Firebase; although completing an introductory Flutter codelab first can be helpful.flutter dart

Effective Dart

Over the past several years, we’ve written a ton of Dart code and learned a lot about what works well and what doesn’t. We’re sharing this with you so you can write consistent, robust, fast code too. There are two overarching themes:

Be consistent. When it comes to things like formatting, and casing, arguments about which is better are subjective and impossible to resolve. What we do know is that being consistent is objectively helpful.

If two pieces of code look different it should be because they are different in some meaningful way. When a bit of code stands out and catches your eye, it should do so for a useful reason.

Be brief. Dart was designed to be familiar, so it inherits many of the same statements and expressions as C, Java, JavaScript and other languages. But we created Dart because there is a lot of room to improve on what those languages offer. We added a bunch of features, from string interpolation to initializing formals, to help you express your intent more simply and easily.

If there are multiple ways to say something, you should generally pick the most concise one. This is not to say you should code golf yourself into cramming a whole program into a single line. The goal is code that is economical, not dense.javascript dart

If you’re developing applications for smartphones, probably you’ve heard of a new development framework, Google’s Flutter. It is a framework that allows you to develop applications with a single code base in the Dart language, also from Google, and publish them for both the Android and iOS platforms.

The framework has not yet reached the 1.0 version, but has already been announced as production ready by Google since its beta 3 version, released in May this year. In addition, there is the possibility of building applications with Flutter for desktop environments (Windows, macOS and Linux), which is the subject that this article will address.

Support for desktop platforms is currently provided through two projects, both still in development. One of them is even developed by Google, but has an indication that the company does not support it.unity flutter dart

In today’s episode we will be showing how to add a GridView to our video game catalog app a.k.a our first Flutter app. If you missed our last episode make sure you check Basic Setup before you continue. Let’s begin!

Open the file named main.dart inside the /lib folder and remove all the sample code that Flutter provides. We want a stripped app.flutter dart

I have to admit, I was missing the gson world of Android after working with JSON in Flutter/Dart. When I started working with APIs in Flutter, JSON parsing really had me struggle a lot. And I’m certain, it confuses a lot of you beginners.

We will be using the built in dart:convert library for this blog. This is the most basic parsing method and it is only recommended if you are starting with Flutter or you’re building a small project. Nevertheless, knowing the basics of JSON parsing in Flutter is pretty important. When you’re good at this, or if you need to work with a larger project, consider code generator libraries like json_serializable, etc. If possible, I will discover them in the future articles.unity flutter dart

A surprisingly important part of good code is good style. Consistent naming, ordering, and formatting helps code that is the same look the same. It takes advantage of the powerful pattern-matching hardware most of us have in our ocular systems. If we use a consistent style across the entire Dart ecosystem, it makes it easier for all of us to learn from and contribute to each others’ code.dart

Observable<T> class

A wrapper class that extends Stream. It combines all the Streams and StreamTransformers contained in this library into a fluent api.dart

RxDart is a reactive functional programming library for Google Dart, based on ReactiveX.

Google Dart comes with a very decent Streams API out-of-the-box; rather than attempting to provide an alternative to this API, RxDart adds functionality on top of it.react dart

In this tutorial, we take a look at futures, streams and some of the other structures that are used for Asynchronous programming in Dart.dart
