The primary goal of Flutter is to create a framework that lets you build mobile applications from a single codebase that looks as well as feels great on any platform. Now we can create eye-catchy mobile apps using Flutter. We have learned a few of the basics of Flutter, and suppose, with those basics, you initiate creating mobile apps and you run into a problem, your mobile app doesn’t look good on every device you are targeting. We aren’t on the web to utilize MediaQueries in the CSS to fix this concern, but there is an effective solution provided by the Flutter team of Flutter app development companies itself.
Flutter is an open-source cross-platform framework that assists us to target all the major platforms, but the sizes of the screen of all those devices are not the same, so we’ve to consider the adaptiveness & responsiveness of the mobile app. Though both of these terms feel similar they aren’t exactly the same.
The diff. b/w an adaptive & a responsive application
Official Flutter documentation says, “Adaptive & responsive can be viewed as separate dimensions of a mobile application: you can have an adaptive application that is not responsive or vice versa. And, of course, a mobile application can be both or neither.”
Responsive
Having a responsive app will definitely catch the eye of users, as it closely corresponds to the screen size. Hire Flutter app developers to get a responsive app. In a responsive app, the layout must be changing itself when there is any change in the screen size or the orientation changes, as this will feel good to the user. This is important when the same mobile application can run on several devices, from a laptop, watch, phone, tablet, or desktop computer.
Adaptive
Adaptive apps imply that mobile apps must adapt to the framework so that they can utilize features that are exclusively available for those platforms or the devices which can be utilized with those platforms only. Adapting a smartphone application to run on multiple types of devices, like mobile, tablet, or desktop, requires dealing with mouse & keyboard input, & touch input. It also implies that there are not the same expectations about the visual density of smartphone applications, how component selection works (cascading menus vs bottom sheets, for instance), utilizing platform-specific aspects (such as top-level windows), & more.
Why should your Flutter mobile app be Responsive?
A Flutter app that is built by a flutter app development services provider, can be easily run on any mobile device, tablet, or even on the TV screen. Nowadays, Smartphone Devices have a number of different screen sizes as well as resolutions, and mobile applications must cater to all such screen sizes. And this does not end here; mobile users can easily rotate their smartphones, and the mobile apps should adjust while viewing or testing on landscape or portrait modes. Catering to so many user needs isn’t an easy task, so the mobile applications should be Responsive enough to meet all such requirements and make sure a seamless user experience.
Examples of Flutter Responsive App
Here are some of the responsive apps made utilizing the Flutter framework that is widely utilized in the market are:
– Google Ads – It’s a mobile app that lets you manage Google ad campaigns directly from mobile devices.
– Reflectly – It’s an AI-powered personal journaling app that assists users in coping with daily stress & negative thoughts by combining cognitive behavioral therapy & positive psychology.
– Lunching – It’s a mobile application that makes it easier to order food. It’s one of the most popular food delivery apps running nowadays.
– Watermaniac – It’s a lightweight water monitoring app made utilizing Flutter, developed by the flutter app development services provider. It helps consumers in focusing on their daily water consumption.
– Cryptograph – This Flutter mobile application assists in monitoring as well as tracking the latest updates on up to 1600 plus global cryptocurrencies like Ripple, Ethereum, Bitcoin, etc.
Is Flutter Responsive By Default?
Flutter applications that are built by the development team of Flutter app development companies aren’t responsive by default. However, the Flutter framework lets mobile app developers create their mobile apps either Adaptive or Responsive. During designing mobile applications with the Flutter framework, there are 2 famous design approaches: adaptive & responsive design. Which we have already discussed above… But if we talk about the Flutter framework, then it’s possible to utilize either adaptive or responsive design. The choice b/w the 2 approaches depends on the specific mobile app needs and the preferences of your potential users. For instance, if your smartphone app is targeted toward a particular kind of device or screen size, an adaptive design may be the better choice. Alternatively, if you want your mobile application to be accessible to a wide range of devices as well as screen sizes, responsive design may be the way to go. Eventually, the choice b/w adaptive and responsive design will completely depend on your requirements as well as the preferences of your target audience.
Is Flutter Framework Still Relevant in 2023?
Flutter framework is one of the most famous frameworks utilized by global mobile app developers of Flutter app development services providers nowadays. As per Statista it is found that Flutter is being utilized by 42% of mobile app developers today & attributing to its ease of usage as well as implementation, the numbers are going to definitely reach the peak level in the future.
Creating a responsive Flutter app
Developing responsive Flutter apps is an easy process and for this purpose, widgets are available out of the box. There are 2 basic approaches to dealing with this scenario.
Utilizing LayoutBuilder class
The following measurement, you can have from this object…
– biggest
– flipped
– hasBoundedHeight
– hasBoundedWidth
– hashCode
– hasInfiniteHeight
– hasTightHeight
– hasTightWidth
– isNormalized
– isTight
– maxHeight
– maxWidth
– minHeight
– minWidth
– smallest.
You can utilize any of these above values to decide how you are willing to render your UI. You can consider any value & can easily alter the layout accordingly. And a great thing is, when the constraints change (for instance, the smartphone user rotates the phone, or puts your mobile application into a tile User Interface in Nougat), the build function runs.
Utilizing MediaQuery.of() method in the build function
This method allows you the orientation, size, etc of the current mobile app. If you are willing to make good decisions based on the complete context instead of just the size of your particular widget, then this is very much useful.
Other useful widgets & classes for creating a responsive User Interface:
– AspectRatio
– CustomSingleChildLayout
– CustomMultiChildLayout
– FittedBox
– FractionallySizedBox
– LayoutBuilder
– MediaQuery
– MediaQueryData
– OrientationBuilder
What to consider while building an adaptive app?
To enhance the UX, you should design your mobile app to accommodate different devices (phones, smartwatches, foldables, tablets, and PCs) with varying sizes, shapes, designs, and OSs. Additionally, you can hire flutter app developers from reliable Flutter app development companies. Your valuable users should be able to explore your mobile app on these varying devices as well as still enjoy the experiences native to the devices & Operating Systems. A vital decision you will have to make in the phase of your app design or development is determining the threshold at which your smartphone app should switch its layouts. In a section of the Android documentation are a set of recommended values to assist you decide the layout of your mobile app across different screen sizes. In so many cases, the available width of the screen could be more significant than its available height because of the influence of vertical scrolling. You will also need to account for the keyboard, touch inputs, mouse, & other characteristics particular to each platform. You should customize the experience & interface of your mobile app to suit the host device.
Utilizing the Flutter Layout Builder to develop an adaptive app
Flutter framework provides many widgets you can utilize while creating your adaptive app. Also, there are a few external packages like the Flutter Adaptive UI & adaptive layout that you can integrate into your mobile app.
The Layout Builder class is very useful for creating responsive & adaptive apps because it has a builder function that it invokes at layout time. This builder function returns a widget, receives the mobile app context as well as constraints, and performs specific operations based on the constraints’ value. For example, you can opt to render a different design while the device width meets a condition specified via the constraints.maxWidth property:
LayoutBuilder(
builder: (ctx, constraints) {
if (constraints.maxWidth < 600) {
return widget;
}else{
return anotherWidget;
}
}
);
