![]() ![]() To do so, we need to navigate inside our shoes_app project and execute this command: flutter pub add webview_flutter Open the command line, and hit this command to create a new flutter project: flutter create shoes_appĪs we have a web URL for our 3D model that we need to display, we will need to install a package called webview_flutter in our project. Here are the widgets that we will need to build for our product screen: Project setup ![]() Widgets are small reusable chunks of code, similar to components in React, Vue, or any other web framework. Now before you start coding you should always analyze the design and visualize how you are going to dissect the structure into widgets. Here is a little GIF of how it looks in action:Īfter you are done with your registration, and picked your 3D model, you can click on the share button and copy the URL to your 3D model. With help of Vectary users can rotate a product vertically and horizontally, and also zoom in and out. We can pretend that those are new shiny Nike shoes. Here is the final version of the screen that we will build: Requirementsīefore we jump to the coding part, we will need a 3D model of our product screen.įor that purpose, we will use Vectary as it offers free-to-use 3D models.Īfter you create a new account there, you can pick any 3D model you want but in this article, we will use a 3D model for shoes. Users love attractive and cool-looking features in the applications, so today we will learn how to create a super awesome yet easy-to-implement 3D product screen in Flutter. 7 min read Photo by Omar Prestwich / Unsplash.We have a MyApp class called at the beginning. Here’s the view of your app on the first run. Once your emulator is up and running, press F5 to run the app in the emulator. Open the repo in Visual Studio Code and spin up your emulator (you may connect your mobile device, too). Run the following command to install all the dependencies: cd Flutter-Custom-Widget/įlutter pub get Install app dependencies Install Flutter dependencies Run the App The initial code will be in the master branch and the final code will be in the refactor branch. I’m switching to a refactor branch (you don’t need to) because I want you all to have a look at my initial and final code. Git clone Clone the repo Clone the Flutter Custom Widget repo from GitHubīy default, it’ll be in the master branch. Pull the code from GitHub by running the below command: git clone Instead of starting from the scratch, I’ve created a Flutter app in GitHub and added duplicated code/components in that repo. This abstraction promotes modularity, making it easier to understand, test, and maintain the code. This allows other developers to use the widget without worrying about its internal workings. You can create high-level widgets that expose a simplified interface and handle the internal logic. AbstractionĪnd finally, custom widgets provide a level of abstraction that hides the implementation details and complexity of a particular UI element. They also enable developers to define a consistent and unified UI design across their application. This separation makes it easier to locate, modify, and debug code related to a particular UI component. By encapsulating specific functionality or visual representation, custom widgets create a separation of concerns. MaintainabilityĬustom widgets contribute to the maintainability of the codebase. Once created, custom widgets can be used multiple times throughout the application, reducing code duplication and promoting a modular development approach. Code ReusabilityĬustom widgets allow developers to encapsulate complex functionality and appearance into reusable components. There are a number of reasons to build build custom widgets in Flutter. They also promote code re-usability and enhance the maintainability of your Flutter applications. Why Use Custom Widgets?Ĭustom widgets help you encapsulate complex UI elements. And what we call props in React are called parameters in Flutter. If you're switching from React Native, you can think about custom widgets as custom React components. They allow developers to create reusable UI components that can be used throughout the application. In Flutter, a custom widget refers to a user-defined widget that encapsulates a specific set of functionalities or visual representations.Ĭustom widgets are the building blocks of a Flutter application. In this tutorial, you'll learn how to replace a duplicated component by building a custom widget in Flutter. One such refactoring technique is extracting duplicated code and components and reusing them in multiple places. You often have to refactor your code to maintain the app’s performance. You can use it to build complex applications that work smoothly on MacOS, Windows, and Linux.īut building these applications is not always a simple process. Flutter has been getting more and more popular lately. ![]()
