Introduction To Custom Layout In Flutter
Changes are part of the app configuration. By rotating the phone horizontally or vertically, the keyboard pops up. Flutter layout emphasizes creating flexible and adaptive UIs that can respond to changes in device orientation, screen size, and other configuration settings. With a flutter layout grid, you can build complex UI designs that are optimized for a wide range of device configurations.
Unlimited variations of screen sizes have been discovered with the release of foldable smartphones, and multi-feature windows for Android and Catalyst. Your application is supposed to appropriately react to configuration changes if you want your application design to look polished. Flutter layout offers a wide range of widgets and tools to create flexible and responsive layouts.
Flutter custom widgets framework supports devices that have widely varied screen sizes. Flutter custom widgets framework has the ability to run on a device that is as small as a smartwatch to devices as large as a television. It is always a challenging task to adapt your application to a variety of screen sizes and pixel densities, with the use of the same codebase.
Designing a responsive layout in a flutter layout grid does not have any such hard and fast rules. This article is a comprehensive study of some of the approaches that you can consider while designing such layouts. Flutter custom widgets can be designed to adapt to different screen sizes and configurations. Flutter layout grids and wrap grids provide powerful and flexible options for creating grid-based layouts.
Before starting with building responsive layouts in a flutter layout, let’s get a piece of knowledge on how Android and IOS handle flutter layout design for varied screen sizes. Let’s know about some of the different approaches that are used to handle different screen sizes and different pixel densities. Flutter’s layout design philosophy is based on a variety of approaches to handle different screen sizes and pixel densities.

- Constraint Layout
Constraint Layout is considered one of the revolutionary tools that is introduced in the android world, for UI design. With the help of the constraint layout, one can build the applications with the help of the set of four doubles, which means a minimum and a maximum width, and a minimum and a maximum height can be created. Constraint layouts are used for creating flexible and responsive UI designs that can be easily adapted to different screen sizes and dimensions.
With the help of the constraint layout, you can specify the size and position for each view, considering the spatial relationships with another view in the layout. But the issue still remains in large devices, where resizing the UI components and stretching it is not considered the most elegant way of taking advantage of the screen real estate. This framework is applied to the devices such as smartwatches, that have very little screen real estate.
Constraint flutter Layout is a powerful tool for building user interfaces in Android applications. It allows developers to create layouts that are flexible and responsive to different screen sizes and dimensions. With constraint layout, you can specify the size and position of each view based on its spatial relationships with other views in the layout. This allows you to create complex layouts that are easy to maintain and update.
- Alternative Layout
Alternative layouts for different-sized devices can be used to solve the above-mentioned issues. The split view can be used in the devices such as tablets for providing a good user experience. In android, separate layout files can be defined for different screen sizes, and the switching between these layouts is automatically handled by the Android framework.
For providing the best user experience to its users it’s important to use alternative layouts for different-sized devices, which want to provide the best possible user experience to its users. By using split-view and other adaptive layout techniques, developers can ensure that their applications are both functional and easy to use, regardless of the device which is being used. The android framework is capable of handling the switching between these layouts automatically.
In Android, developers can define different layout files for different screen sizes using the “layout” directory naming convention. For example, “layout-large” would contain the layout file for larger devices, while “layout-small” would contain the layout file for smaller devices. When the app is installed on a device, the Android framework automatically selects the appropriate layout based on the device’s screen size and density.
- Fragments
You can extract your UI logic into separate components by using Fragment, which will be designing multi-pane layouts for large screen sizes, there is no need to define the logic separately in this. You can easily reuse the logics that you have used prior for defining each segment.
Fragments in Android are modular components that can be used to create reusable UI elements and improve the organization of your app’s code. They allow you to break up your UI logic into smaller pieces that can be managed independently and reused in different parts of your app.
For example, if you have an app that needs to display different types of content on a large screen, you can use fragments to define each type of content as a separate component. This makes it easier to manage and modify the UI as you can focus on each component individually.
- Vector Graphics
Vector graphics are the images that are created using pixel bitmaps, which are opposed to being created using pixel bitmaps. Vector graphics are the images that are defined in the XML files in the form of paths and covers. Scaling to the desired size without scaling the artifacts is easily possible in the flutter framework. Vector Drawable can be used for any type of illustration in android applications.
In Flutter custom widgets, vector graphics are defined in the form of paths and shapes using the Flutter App Development Drawing and Painting API. This API allows you to create complex vector graphics with ease, and you can customize their appearance using a variety of styling options such as stroke width, color, and fill. Because vector graphics are defined using mathematical equations, they can be easily scaled to any size without losing quality.
IOS Approach
Flutter layout grid provides a range of layout tools and widgets that enables developers to create powerful layout grid tools. Below is the list of the concepts that are used by iOS for defining responsive layouts. Flutter layout design draws inspiration from a variety of sources, including the layout concepts used by iOS and other platforms. Flutter custom widgets provide a wide range of built-in widgets that can be customized and extended to create custom UI elements.
How Is Flutter Different
If you are not an android or iOS developer, from the above information you might have got the idea of how these platforms are able to handle the responsiveness natively. In the android application, when there is a need to display multiple UI views on a single screen, this can be done by using fragments, which are capable of running inside the activity of an application. Flutter layout grid allows developers to build responsive and scalable UI’s for their applications.
Widgets, a concept introduced by Flutter, are responsible for building blocks that can be connected together to build an entire application. In Fluttre’s framework, every individual screen, even the entire application is also considered a widget. Widgets can easily be reusable, so there is no requirement to learn any other new concept while we are building responsive layouts in a flutter.
Flutter layout design provides a range of pre-built layouts and design patterns that can be used for building responsive and visually appealing layouts for their applications.
Responsiveness In Flutter
While developing a responsive layout, the UI changes the application screen size according to the different mobile sizes. Responsive UI is considered an important element when the application made is the same for mobile, web, and table. Flutter allows the creation of applications that are self-adapted to the device’s screen size and orientation. Flutter custom widgets play a key role in creating responsive UI designs that can be adapted to different screen orientations.
- Media Query
Media Query establishes a sub-tree in which the media queries are resolved to the given data. In the process of developing the application for both android and iOS users, it is essential to have different UI layouts for the different screen sizes for an improved user experience.
Media Query comes into action when the user has the preferences set for the different font sizes. With the help of the media query, you can get information about the current application screen size, and also has the ability to give detailed information about the device.
With the help of MediaQuery.of you can get the information regarding the device you are running on, like the size of the screen, and then build your layout accordingly. The current device’s orientation can be checked with MediaQuery, it can also be used to check if the user has modified the default font size or not.
- Layout Builder
You can get the box to constrain objects with the help of Layout Builder. These are used to determine the maximum widget and maximum height of a particular widget. It allows you to create a custom layout that adjusts their size and position based on the available space. This object contains the minimum and maximum widget and height that the parent widget can give to the child’s widget.
You can use the box constraints object to make more complex layout decisions. For example, you could set a maximum widget and height for your child’s widget and then center it with the available space. Access the box constraints object you can pass a callback function to the builder property. Inside the callback function you can use the box constraints object to make the layout decisions.
Layout Builder is a useful widget for creating custom layouts that adjusts their size and positions based on their available spaces. It allows you to access the box constraints of the object which provides information about the parent widgets’ constrain, such as maximum widget and height. Responsive layouts can be created with the help of these layout builders.
- Orientation Builder
The OrientationBuilder widget is a Flutter custom widget that allows you to build different UI layouts based on the orientation of the device. It provides a callback function that returns an Orientation object, which indicates the current orientation of the device. You can then use this information to build different layouts for portrait and landscape modes.
In iOS development, you can use size classes to create different layouts for different devices and orientations. For example, you can use size classes to create a layout that is optimized for both iPad and iPhone devices in both portrait and landscape mode.
To use size classes in iOS development, you typically use Auto Layout and constraints to build your UI. You can then use size classes to create variations of your layout for different devices and orientations. In Flutter custom widgets, you can achieve similar results using the MediaQuery widget and its properties, such as MediaQueryData.orientation. You can use these properties to build different layouts for different screen sizes and orientations.
Conclusion
