How to Build a Responsive Web Application using Flutter
Since the advent of mobile devices and the Age of Connectivity, responsive interfaces have become an expectation of website and app users. Even though many frameworks can help you achieve a successful responsive design, you should pay special attention to the one that offers cross-platform support for everything from your iPhone to your toaster: Flutter. Are there any benefits and features that you can use to your advantage when designing responsive apps and websites? Join us for an exploration of the possibilities that Flutter offers for successful responsive design.
In the mobile arena, Flutter has already made quite a splash. With its expansion into larger devices, it looks set to make even bigger waves. The technology is simple to implement and platform-neutral as well. In this article, we will examine the steps involved in creating a responsive web application using Flutter. We will look at how to build a web application that is responsive to layout and screen size changes.
Building a responsive web application using Flutter
Flutter is the next big thing in app development. As a result, we now understand why it is important to create a Flutter-based responsive web application. But where do we start from? As long as you’re covered, you don’t have to worry. Our following discussion will focus on the characteristics that determine the responsiveness of a Flutter web application.
Use MediaQuery for layout
The MediaQuery library is an essential component of the Flutter framework. It determines the layout of the application. Optimizing layout changes is made much easier with this approach. Depending on the layout – either landscape or portrait – it can be made responsive.
Implementing layout and orientation using widgets
LayoutBuilder and OrientationBuilder represent alternatives to traditional MediaQuery when it comes to making layout changes. Widgets may not function properly if not optimized correctly. You can run your applications on various screen sizes and layouts by using these two options.
The FittedBox
Flutter’s FitteBox widget is essential for auto-sizing text based on the parent widget’s size. Randomly increasing font size can be difficult for users since it can go beyond the box. By using the FittedBox widget, users can scale the font according to the size of the parent widget.
Fix the broken gallery
When the aspect ratio is not taken into consideration, layout and screen orientation problems may arise. Exactly what is the aspect ratio?
Boxes are measured by their aspect ratio, which is the distance between their height and width. The AspectRatio widget option allows it to resize itself freely in accordance with screen orientation. When in landscape mode, it will look different from when in portrait mode.
Multi-Child Custom Layout widget
Flutter has an area of functionality called CustomMultiChildLayout which allows the widgets to form their own layouts depending on the layout type. This widget should be used to allow the user to arrange for the children to be passed in a single operation. It’s possible to determine their order and size independently.
Declarative UI
From Android to iOS, UI development usually takes place in an imperative manner. This is the most commonly used UI programming and developers can manually build a fully operational UI entity.
Flutter developed Declarative UI to alleviate the burden of producing traditional UI programming. Developers declare the current state of UI and Flutter handles the transitions.
Work with the Flutter elements
The development phase of the Flutter web application includes some key aspects we need to know. Among them are:
Orientation
To determine a layout, it is necessary to understand the type of layouts available on the devices as well as be able to identify a layout based on the device. A landscape or portrait layout can be chosen.
Device Screen Type
To determine what device screen type our content is displayed on, we need to know the screen type of the device. There are many types of device screens, including mobile screens, tablet screens, computer screens, and more.
Screen Size
App developers need to know the total screen size before they begin building their applications. Flutter developers will have a difficult time defining the available screen sizes if they do not know the available screen sizes.
Local Widget Size
The resulting intuitive UI allows users and developers to choose a UI choice within the Flutter widget.
Final Verdict
The following explanations provide a number of practical insights from the perspective of developers that you may find useful when considering Flutter. To develop a successful application, it is also crucial to select the best technologies and develop a strong development team.
Ready for the tweaks in your web application? Well, it is not a difficult task at all to build a Flutter web application. The challenge arises when web app developers need to make it responsive across all platforms.
In the last few years, Flutter has become the most in-demand framework in the app development market, so most of them prefer to hire Flutter app developers and take advantage of its features.
