 Material 3 in Flutter Application




  • What is Material 3 ?

Flutter is a popular open-source framework for building high-quality, cross-platform mobile applications. Material Design is a set of design guidelines created by Google that outlines the design principles for creating consistent and visually appealing Android applications. Flutter provides built-in support for Material Design, allowing developers to easily create beautiful and responsive applications.

 

In this blog, we'll explore Material 3 in Flutter and provide a demo of how to implement it in your project.

 

Material 3 is the latest version of Material Design, Google's design language for building user interfaces across various platforms. Material 3 is a significant update to Material Design, offering new design principles and components that enable developers to create more immersive and engaging user interfaces in their Flutter applications.

  • Key features of Material 3 in Flutter
  1. Increased Depth and Realism: Material 3 introduces a greater emphasis on depth and realism through the use of shadows and gradients. This creates a more immersive user experience, making the interface feel more tactile and responsive.
  2. Improved Typography: Material 3 introduces a new font called Google Sans that is designed to be highly readable and adaptable across different devices. The updated typography helps to improve the overall legibility of the interface.

  3. Enhanced Motion: Material 3 encourages the use of motion to convey meaning and create a more engaging user experience. Animations and transitions can be used to guide the user's attention and provide feedback.

  4. New Components: Material 3 introduces new components that enable developers to create more dynamic and responsive user interfaces. These components include the Bottom Sheet, Navigation Rail, and the Floating Action Button (FAB). The Bottom Sheet provides a slide-up panel that can display additional content or actions. The Navigation Rail allows for easy navigation between different sections of the app, and the FAB is a prominent button that can be used for the most important action in the app.

  • How to enable Material 3 in Flutter

       In wake of Material 3's announcement, Flutter has received several updates to support it, including new typography, shapes, elevation, updated widgets, and new  M3 widgets. 

Most M3 components are available in Flutter. If you wish to support Material 3 changes, you must use the useMaterial3 flag on ThemeData. (This might change in the future, so be sure to check the Flutter  website for updated information.).


To use Material 3 in Flutter instead of Material 2, specify the following:

         
theme: ThemeData(
  useMaterial3: true,
),


  • New in Material 3 design:

  1.  Updated typography: Material Design 3 introduces updated typography with new font weights and styles that allow for more flexible and expressive typography.

  2. Redesigned icons: The new Material Design 3 icons have been redesigned to be simpler and more consistent with each other, making it easier to recognize and understand the meaning behind them.

  3. Updated color system: The color system in Material Design 3 has been updated with new colors and a revised color palette that provides more options for designers to create accessible and beautiful interfaces.

  4. New layout system: Material Design 3 introduces a new layout system called Flex Layout that provides more control over how widgets are arranged on the screen. 

  5. New shape system: The shape system in Material Design 3 has been updated with new shapes that allow for more expressive and dynamic UI designs.

  6. Enhanced theming capabilities: Material Design 3 provides enhanced theming capabilities that allow for more customization and flexibility in the look and feel of an app.

 Flutter if & else: 3 ways of implementation if and else statements allow developers to execute different blocks of code based on specific conditions. This can help to create more dynamic and responsive user interfaces by allowing the app to respond differently to different inputs or user interactions.    The Problem: In contrast, Flutter provides an error message when you attempt to use the if-else statement directly within your widget.                  Unfortunately, you can’t write if statement inside your widget as if you were writing in your method or function. But there are a few ways you can write a conditional statement inside your widget. Let’s see them.                A description of how to use an If Else Statement in a Flutter           widget: Using the Ternary Operator Using the Spread Operator Using the Method ...

  Migration to null safety in flutter. Problem Statement:   The newer versions of Flutter supports null safety but the older versions of Flutter does not have this type of support, and to run older applications makes it difficult to build or run the application  in it. To overcome this problem we need to perform a migration of versions. Solution of this problem: Firstly we need to check the version of dart. It should be greater than or equal to 2.12. To check the version of dart use the following command dart --version After that we need to check dependency status, use the following command to perform the dependency status check dart pub outdated --mode=null-safety Here’s an example of the output for a simple package. The green checkmarked version for each package supports null safety: Before migrating the package’s code, update its dependencies to null-safe version: Run dart pub upgrade --null-safety to upgrade to the latest versions supporting null safety.  Note: ...
