What’s important is determining early in the discovery and design phase which app development approach is right for your goals. In fact, the three main types – native apps, cross platform apps, and mobile responsive websites – all sport their own advantages and disadvantages. However, there are many different approaches, technologies, and techniques that can be used to build an app. REMEMBER: This is different from the device orientation that you can retrieve by using MediaQuery.Unless you get a glimpse behind the scenes, it’s easy to assume mobile apps are all developed the same way. To determine a widget’s current orientation, you can use the OrientationBuilder class. Style: TextStyle(color: CustomColors.android, fontSize: 18), You can use MediaQuery to retrieve the size (width/height) and orientation (portrait/landscape) of the screen.Ĭlass HomePage extends StatelessWidget build(BuildContext context) ', Responsiveness in FlutterĪs I said earlier, I will go over the important concepts that are required for developing responsive layouts, and then, it’s your choice how exactly you want to implement them in your app.
Widgets are reusable by nature, so you do not need to learn any other concepts while building responsive layouts in Flutter.
Remember that in Flutter, every screen and even the entire app are also widgets! Basically, they are the building blocks that can be connected together to build an entire app. In iOS, UISplitViewController, which manages child view controllers in a hierarchical interface, is used for controlling multiple view controllers.įlutter has introduced the concept of widgets. You can run multiple Fragments inside an Activity, but you cannot run multiple Activities in a single app at the same time. In Android, to display multiple UI views on a single screen, you use Fragments, which are like reusable components that can run inside an Activity of an app.

How Flutter differsĮven if you are not an Android or iOS developer, by this point, you should have gotten an idea of how these platforms handle responsiveness natively. There are a few other UI elements that you can use for building responsive UIs on iOS, like UIStackView, UIViewController, and UISplitViewController. On iPad, size classes also apply when your app runs in a multitasking configuration. iOS dynamically makes layout adjustments based on the size classes of a content area. Size classes are traits that are automatically assigned to content areas based on their size. Auto Layout automatically readjusts layouts according to the specified constraints when certain environmental variations (known as traits) are detected. Auto LayoutĪuto Layout can be used for constructing adaptive interfaces where you can define rules (known as constraints) that govern the content in your app. The concepts used by iOS for defining responsive layouts are as follows: 1. In Android, you can use VectorDrawable for any kind of illustration, such as icons. They can scale to any size without scaling artifacts. Vector graphicsĪs opposed to being created using pixel bitmaps, vector graphics are images defined in XML files as paths and colors. You can just reuse the logic that you have defined for each fragment. Using Fragment, you can extract your UI logic into separate components so that while designing multi-pane layouts for large screen sizes, you do not have to define the logic separately. In Android, you can define separate layout files for different screen sizes, and the Android framework handles the switching between these layouts automatically as per the screen size of the device. For example, you can use split view in devices like tablets to provide a good user experience and use the large screen real estate wisely. To solve the above issue, you can use alternative layouts for different-sized devices. This also applies to devices like smartwatches, which have very little screen real estate, and resizing the components to fit that screen size might result in a weird UI. ConstraintLayout allows you to specify the position and size for each view according to spatial relationships with other views in the layout.įor more information regarding ConstraintLayout, check out this article here.īut this does not solve the issue with large devices, where just stretching or resizing the UI components is not the most elegant way of taking advantage of the screen real estate. It can be used for creating flexible and responsive UI designs that adapt to different screen sizes and dimensions. One of the revolutionary tools introduced in the Android world for UI design is the ConstraintLayout. In order to handle different screen sizes and pixel densities, the following concepts are used in Android: 1.
