10 tips and tricks you can use in Flutter

Nowadays, if you ask any mobile application developer what is their favorite programming language for developing cross-platform applications? You will hear only one answer that is “Flutter”. Flutter already made the process of mobile application development easy. But there are many tips and tricks which developers can still use to increase their productivity. These tricks will save your time and will help you in increasing productivity. Think of this as a pathway to becoming a top flutter developer. So, let’s have a look at a few tricks which might help you in your Flutter Application development journey.

Using const constructor:

Canonicalization is the process of converting data having more than 1 representation into a standard canonical representation. Const constructor creates a “canonicalized” instance. That means all constant expressions begin canonicalized, and later these canonicalized symbols can be used to recognize equal of these constants. One of the most important tricks in flutter might come in handy during flutter app development. By using const constructor you can stop rebuilding unwanted widgets. 

Format code using dart fmt:

In Flutter if you want to format your code then you can use dartfmt. Now there are multiple options available in Flutter that are dart format, flutter format, and dartfmt. But don’t worry they all do the same thing. Still, dartfmt is the original formatter. To provide a more simple and unified command-line interface, many Dart command-line tools are packaged as subcommands of the dart. For example, dartfmt stands for dart format, dartanalyzer is dart analysis and the pub is dart pub.

Spread operator:

The spread operator is also represented as triple dots (…). The spread operator is used to extend the variables/elements of a collection. This feature was not available before but now it is included with the release of Dart 2.3. Before, Dart 2.3 you would require to use addAll to combine the two lists. Now, it is easier by using the Spread operator.

Extension methods

Extension methods are used to add additional functionalities to the libraries. It was first introduced in Dart 2.7. Suppose you are using someone’s API and you want to add some functionalities to it. But it’s not possible to change the API. Extension methods are present in the library and to use it just import the library it’s in and use it like you normally do.

Cascade operator

Just as the triple dot (…) is a spread operator, double dot (..) are known as cascade operators. This operator allows developers to perform a number of operations on the same object. This operator saves many steps in code. Cascade operator helps in saving time when multiple method calls are being made on the same object.

SafeArea class

Sometimes phone notches can create big problems by cutting the content of your application’s UI. In such cases, you can use the SafeArea class widget which can modify its child class by providing the necessary padding required. This widget makes use of MediaQuery to check the dimension of the phone screen and will pad the child widget accordingly, to match the phone screen in order to avoid notch interference. 

GetIt

The more time you spend on your project, the more it will grow in size. Then you will need to separate your app’s logic from widgets. Keeping widgets from having dependencies makes code organized. It’ll be easier to test and maintain your code. But now how will you access these objects from your UI code? You can use Getit as a simple locator. It can be used to access projects from your UI. Also, Getit is easy to use and fast to learn. 

Using Flutter Snippet

Flutter snippets can help you in increasing your productivity in the long term. You can create Flutter classes and methods easily. For example, you can use animatedBldr shortcuts to create an animated builder widget and customPainter to create custom paint widget. Flutter snippets can be used in Android studio as well as Visual studio code.

IntroductionScreen 

Let’s say you have just started using Flutter and want to create an intro screen. But you don’t have any idea how to create an awesome intro screen. In this case, IntroductionScreen can help you. This widget will let you have a screen at the launcher and you can explain your application. IntroductionScreen can be customized with great design.  

Using Font Awesome to create icons

What would you do if you wanted to create mind-blowing icons? You don’t need to be a graphic designer if you want to create stunning icons. You can use the font_awesome_flutter package. By using this package you can get a complete set of Font Awesome icons. Icon names are written in lower camel cases.
