The use of the 'RaisedButton' widget in software development has been established as a staple in the design of graphical user interfaces (GUI) for several years now. However, over time, newer and better widgets have replaced the need for the 'RaisedButton' widget to the point that it has been marked for deprecation in certain implementations. Therefore, it is recommended that developers should avoid using 'RaisedButton' in their projects.
A deprecated widget is one that is no longer supported or recommended in its development framework. While many developers may be accustomed to using 'RaisedButton' functionality in their GUI development, it is essential to understand that the continued use of deprecated widgets like 'RaisedButton' may negatively impact the stability and efficiency of your code.
The main reason 'RaisedButton' is marked for deprecation is design evolution. User interface design has evolved from the conventional flat button design: a rectangular button with no shadows or corner radii. The new design incorporates more interactive cues like rounded corners and drop shadows to make them more meaningful and attractive to users. This new design principle is referred to as Material Design, which is Google's design philosophy that encourages visually appealing interfaces that are also easy to navigate.
In the Material Design system, buttons come in three styles: flat, raised and floating. Flat buttons are used in places where you want to provide less emphasis on action, raised buttons for primary actions, and floating buttons should be reserved for highly contextual, on-screen user actions.
Nowadays, the 'RaisedButton' widget appears somewhat outdated, particularly when compared to the sleeker and more modern widgets of recent frameworks like the Flutter SDK. Unlike 'RaisedButton,' Flutter widgets incorporate Material Design principles closely, which makes them appear more modern and interactive.
To demonstrate a practical example, let us compare the use of 'RaisedButton' with its modern equivalent, 'ElevatedButton' in designing a simple application in Flutter.
import 'package:flutter/material.dart';
void main() {
runApp(const MyApp());
}
class MyApp extends StatelessWidget {
const MyApp({Key? key}) : super(key: key);
// This widget is the root of your application.
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'RaisedButton vs ElevatedButton',
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: const Scaffold(
body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
children:
//RaisedButton
RaisedButton(
onPressed: () { },
child: const Text('RaisedButton'),
),
//ElevatedButton
ElevatedButton(
onPressed: () { },
child: const Text('ElevatedButton'),
),
],
),
),
),
);
}
}
From the code example above, it is easy to see that 'LayoutButton widgets are higher-level widgets compared to 'RaisedButton' because it automatically adheres to Material Design principles. ElevatedButton provides a more modern and interactive user experience as opposed to the archaic 'RaisedButton'.
In conclusion, if you're beginning a new Flutter development project, we recommend using ElevatedButton or any other elevated button widget options instead of 'RaisedButton'. It is essential to adopt the more current and modern widgets in your software development project. For older projects that utilize 'RaisedButton,' now would be an excellent time to update your code base and keep up with modern design standards!
I can provide more details about the topics discussed earlier.
First, let me elaborate more on Material Design. As I mentioned earlier, Material Design is a design philosophy introduced by Google. It aims to provide a visually appealing and easily accessible experience for users. The principles of Material Design include using a grid-based layout, consistent color schemes, meaningful animations, and realistic lighting effects like shadows and highlights. The design language emphasizes the use of typography, imagery, and motion to create an engaging experience. Material Design evolved from the earlier Holo design language of Android, which featured flat and minimalistic designs. The Material Design guidelines have now been adapted by developers across various platforms and are widely used in the development of modern applications.
Next, let's discuss Flutter, which is an open-source UI toolkit for developing applications for Android, iOS, and the web. Flutter provides developers with a modern and reactive programming model that enables the creation of beautiful and performant applications with a single codebase. Flutter uses its rendering engine and its widgets to create visually appealing designs on multiple platforms. One significant advantage of Flutter is that it can compile code natively for different platforms, making the apps highly performant and fast. It also provides developers with a rich set of widgets and tools to create beautiful, responsive, and easily customizable UI.
Finally, let's talk about why it is essential to keep up with modern design standards and why using deprecated widgets can be harmful. As technology is continuously evolving, design standards are constantly changing. Modern design principles are built around providing a seamless and intuitive user experience to the user. By using modern widgets, developers can adhere to current design principles and effectively engage with users. Deprecated widgets like 'RaisedButton' can cause compatibility issues, decrease performance, and provide an outdated user experience. Therefore, it is essential to keep up with the latest design and development trends for creating successful applications.
Popular questions
Here are five questions about 'RaisedButton' being deprecated and its alternatives, with answers:
-
Why is 'RaisedButton' marked for deprecation?
Answer: The use of 'RaisedButton' is marked for deprecation because of the evolution of user interface design. New design principles like Google's Material Design incorporate more interactive cues such as rounded corners and drop shadows, making them more attractive and user-friendly. The modern 'ElevatedButton' widget used in Flutter strongly adheres to these design principles. -
What is Material Design, and why is it essential for the creation of modern mobile applications?
Answer: Material Design is a design philosophy introduced by Google that provides a visually appealing and easily accessible experience for users. It aims to create a seamless and intuitive experience through the use of a grid-based layout, consistent color schemes, meaningful animations, realistic lighting effects, and typography, imagery, and motion. It is essential for the creation of modern mobile applications to provide a visually engaging and user-friendly experience. -
What are some of the advantages of using Flutter in mobile application development?
Answer: Flutter is a modern, open-source UI toolkit that provides developers with a reactive programming model that enables the creation of beautiful and performant applications with a single codebase. Flutter uses its rendering engine and widgets to create visually appealing designs on multiple platforms. It also provides developers with a rich set of customizable widgets and tools that make it easier to create responsive and beautiful UI.

Can you use 'RaisedButton' in old projects, or should developers update them to modern widgets?
Answer: While developers can still use 'RaisedButton,' it is recommended to update old projects that use 'RaisedButton' to modern alternatives like 'ElevatedButton.' An outdated widget like 'RaisedButton' can cause compatibility issues, decrease performance, and provide an outdated user experience, making it essential to keep up with the latest design and development trends for modern applications. -
What are the features of the 'ElevatedButton' widget, and why should developers use it instead of 'RaisedButton'?
Answer: The 'ElevatedButton' widget, introduced with Material Design, is a modern alternative to 'RaisedButton' that strongly adheres to contemporary design principles. ElevatedButton widgets have a built-in elevation feature that creates a more modern design, indicating a button's importance. It also provides better accessibility to users with varied abilities. Compared to 'RaisedButton,' ElevatedButton provides a sleeker and more modern design, making it more attractive to users.
