Hybrid mobile applications came into existence in 2011 with the signature products, namely Xamarin SDK with C#, which this platform revolutionary, since then. After this, many hybrid mobile applications were introduced in the market to ease the lives of coders to write one code for many platforms.<\/p>\n

Later, Google turns to put its finger in the pie with Flutter! In the year 2017, Google released it\u2019s first-ever Flutter 1.0 version, after keeping it in beta mode for 18 months.<\/p>\n

<\/span>What is Dart?<\/span><\/h2>\n

Dart is a programming language used for coding apps in Flutter<\/strong><\/span><\/a>, which is also considered as another product by Google released in the same year.<\/p>\n

With the evolving trends, it is important that companies update and offer something new to their users to maintain that spark in the relationship. That\u2019s what Google did by upgrading Dart and recently released Dart 2.3!<\/p>\n

This actually comes with a new set of new changes in the library as well as language. However, Google entirely focused on the Collections part with an aim to make Collections more expressive and declarative.<\/p>\n

<\/span>How to explore these new features and changes in Dart 2.3?<\/span><\/h2>\n

Here\u2019s the list of significant changes in the Dart 2.3, in brief:<\/strong><\/p>\n

<\/span>1. The Spread operator (\u2026)<\/span><\/h3>\n

As per the image, consider the following list of text widgets.<\/p>\n

\"The<\/p>\n

Earlier, when you have to add all these to a ROW widget, you normally do something like this:<\/p>\n

\"ROW<\/p>\n

The issue with this technique was that if you wanted to add Asian countries first and then add North American countries, you would have to first include Asian countries in a row, somewhat like this:<\/p>\n

\"Dart<\/p>\n

This ultimately demands you to reorder the Adderall methods to your list, which is not convincing and ideal at all.<\/p>\n

But now, enter the new Spread operator to achieve the above results seamlessly:<\/p>\n

\"Dart<\/p>\n

Further, this can be simply reordered like so:<\/p>\n

\"Row\"<\/p>\n

<\/span>2. Utilizing \u201cif\u201d in a Collection<\/span><\/h3>\n

The all-new Dart 2.3 enables you to utilize if\/else statements in Collection literals without any hassle. For example, look at the following \u201cpre-Dart 2.3\u201d image where we put on view Asian countries, only if the user is exactly from an Asian country:<\/p>\n

\"Utilizing<\/p>\n

But with the new version of Dart this how you could go about doing things:<\/p>\n

This makes content more readable and clear for every flutter development company.<\/p>\n

<\/span>3. Utilizing \u201cfor\u201d in a collection<\/span><\/h3>\n

Suppose you want to revise your \u201cEuropean countries list\u201d before utilizing the list anywhere. To exhibit the new Dart feature, let\u2019s just prepend \u201cnew\u201d before all the countries. Things were something like this before Dart 2.3 arrived to take this step:<\/p>\n

\"Dart<\/p>\n

And this how you will do in all-new Dart 2.3:<\/p>\n

There are some more changes in the tool aspect of Dart 2.3, let\u2019s take a look at them as well:<\/p>\n
