Here, in this blog, I will be discussing how you can optimize your Flutter app with best practices of the object-oriented programming language of Flutter, Dart!

Again every project has its own functionality and nature but most of the practices are a kind of standard practices which has been practiced by the global Flutter community.

So, let’s get started!

Using Call method

To create a callable class that can work well as a class instance function Dart can be an extended hand.

This can be implemented by call() method, for example, have a look at the below syntax

class class_name { … // class return_type call ( parameters ) { … // call the function content } } With the example, class EducativeIntro { // Defining call method String call(String a, String b, String c) => ‘Welcome to $a$b$c’; } // Main Function void main() { var educative_input = EducativeIntro(); // Calling the class through its instance var educative_output = educative_input(‘our ‘, ‘Dart ‘, ‘tutorial’); print(educative_output); }

Enhance the experience

One of the ideal IDE for flutter that feels like home is Android studio. If you want to build an iOS version as well, you will surely need to work on macOS as well and have to install Xcode.

Fo this sort of matter, we will come to our most important feature of Flutter and Dart which is Hot reloading!

This can repaint the widget that has changed the widget tree in your application code.

Any functionality which is unaffected by that code will stay unaffected and as the name suggests it will show the rapid change in no time.

Reformatting the code

It will take no time to look like a portion of spaghetti for any nested widgets in the Flutter App Development process. So it becomes essential to build your code neat.

Dartfmt is the tool that will straighten your code in no time by reformatting it. It also has this smart which enables it to reformat your code by eliminating any comas you have put in between, and it does it automatically while you save the file.

This will eliminate your manual efforts to eliminate them one by one.

Wrapping your components

So conventionally, to reduce the complexity and make your development process bulletproof we have been wrapping the components with a container.

Flutter Outline Android studio lets you do this task with just a single click.

Doing Copy/ Paste was so last year, try this instead. While extracting name your widget and there you go! You have yourself a personalized custom widget.

You will see something like this.

Converting to StatefulWidget

Often in the middle of the development process, you realize your stateful widget has to be stateful but fortunately in Flutter.

The pro tip here that works best is, you can create the new widget and type stful and stless and will generate the widget automatically by respective order.

To conclude things, Dart and Flutter are like hand and glove when it comes to building high-performing applications.

If you know when to make the right move you can find the jackpot in terms of reaching a smooth and unique user experience as well as a hassle-free Flutter App Development Process!
