To dive into the world of Material 3, simply set useMaterial3: true in your MaterialApp theme. Even when creating a new app using the flutter create command, this option will be automatically added to your theme settings.


Unleash your creativity and make your app truly unique with custom color schemes! With M3 components, you have the power to customize the default colors of your theme’s ColorScheme. Whether you prefer starting with a single “seed” color or drawing inspiration from an image, the possibilities are endless. Our demo allows you to experiment with different options, generating visually pleasing and accessible color schemes.

What is Cross-Platform Mobile App Development?

Cross-platform mobile app development involves building applications that can be deployed on multiple platforms, such as iOS and Android, using a single codebase. This approach saves time, effort, and resources compared to developing separate native apps for each platform. Several frameworks and tools enable developers to achieve cross-platform compatibility efficiently.

Navigation Bar

A fantastic addition to Flutter’s M3 lineup. This version brings a fresh twist to the familiar BottomNavigationBar widget, featuring vibrant colors, enhanced highlighting, and a subtle elevation effect. Despite these visual upgrades, the NavigationBar continues to function just as it did before.
For those who wish to customize the default appearance of NavigationBars, simply utilize the NavigationBarTheme widget. While migrating existing apps to this component is not mandatory, we highly recommend leveraging its capabilities when developing new applications.


Discover the versatile NavigationDrawer, a destination selection widget inspired by M3 design principles, built upon the foundation of the Drawer widget. With the NavigationDrawer, you can effortlessly present a list of NavigationDestinations widgets for single-selection purposes. Feel free to incorporate additional widgets within this list to enhance its functionality. If the need arises, the NavigationDrawer gracefully accommodates scrolling.
For a touch of personalization, the appearance of the NavigationDrawer widget can be customized using the NavigationDrawerTheme widget, allowing you to create a unique and tailored experience.

SearchBar & SearchAnchor

Introducing SearchBar and SearchAnchor, two powerful components that offer predictive text for search queries. When a user enters a search query, the app intelligently generates a list of matching responses within a dedicated “search view”. The user can then select a response or fine-tune their query as needed. To customize the design of these components beyond the M3 style, you can leverage the flexibility of SearchBarTheme and SearchAnchorTheme widgets.
These widgets empower you to override the default M3 design and create a personalized look and feel that aligns with your app’s unique aesthetic.

Secondary Tab Bar

With M3, you can now create a secondary tier of tabbed content. To differentiate this second TabBar, simply utilize the TabBar.secondary option. This allows for a visually distinct and organized presentation of your tabbed content.

Revamped DatePicker for M3

Prepare to be delighted by the enhanced M3 DatePicker, featuring vibrant colors, improved layout, and refined shape for both the calendar and textfield versions of this widget. Rest assured, these updates won’t alter the existing API; instead, they introduce an exciting addition known as the DatePickerTheme.

TimePicker Enhancements for M3

In line with the M3 design principles, Flutter widgets has given the TimePicker a makeover, just like we did with the DatePicker. The colors, layout, and shapes of both the regular and compact versions of the widget have been updated for a more cohesive and visually appealing experience.

M3 Enhancements to ListTile

In the world of M3, the ListTile has received a makeover by enhancing its positioning and spacing. This includes adjustments to content padding, alignment of leading and trailing widgets, minimum leading width, and vertical spacing. Rest assured, the API stays unchanged, ensuring a seamless transition.

Drawer Enhancements for M3

Experience the revamped M3 Drawer, where colors, elevation, and subtle layout adjustments come together to create a fresh and delightful interface.
come together to create a fresh and delightful interface. Triple-click/tap gestures for TextFields offer intuitive and efficient text selection options. Let’s explore the different behaviors based on the platform:
Triple click:

– When used in a multi-line TextField (Android/Fuchsia/iOS/macOS/Windows), it selects a paragraph block at the clicked position.

– In a multi-line TextField on Linux, it selects a line block at the clicked position.

– For single-line TextFields on any platform, it selects the entire text.

Triple tap:

– In a multi-line TextField, it selects a paragraph block at the tapped position.

– For single-line TextFields, it selects the entire text.

Triple click + drag:

– When performing a triple click followed by dragging the choice, it extends the selection in paragraph blocks on Android/Fuchsia/iOS/macOS/Windows.

– On Linux, it extends the selection in line blocks.

Flutter supports Supply Chain Levels for Software Artifacts (SLSA) Level 1, strengthening its commitment to security. The Flutter Framework has undergone significant enhancements, incorporating a range of security features, including:
  1. Streamlined Build Process: The build scripts for Flutter now facilitate automated builds on trusted platforms. By leveraging secure architectures, the risk of tampering with artifacts during the build process is minimized, thereby enhancing the overall security of the supply chain.
  2. Multi-Party Approval and Audit Logging: Release workflows within Flutter now require approval from multiple engineers before execution. This multi-party approval process ensures accountability and transparency. Detailed audit logs are generated, capturing every step of the execution. These measures safeguard against unauthorized modifications between source code and artifact generation.
  3. Provenance Assurance: Beta and stable releases of Flutter now come with built-in provenance. This means that the framework release artifacts are constructed from trusted sources with verifiable content. Each release provides links that enable users to view and validate the provenance information on the SDK archive, ensuring the integrity of the supply chain.
By embracing SLSA Level 1, Flutter fortifies its security measures, providing developers and users with a heightened level of confidence in the authenticity and reliability of the framework.

Flutter Web Application Development

Flutter web apps now have improved load times for web integration thanks to reduced file sizes of icon fonts. Unused glyphs from both Material and Cupertino have been trimmed down.
CanvasKit has been optimized to occupy even less space for Chromium-based browsers. By leveraging a customized CanvasKit variant served from Google’s top-tier CDN, performance is expected to be further enhanced.
Element embedding is now possible, allowing Flutter web apps to be served within a specific element on a page. Prior to this release, apps were limited to occupying the entire page body or being displayed within an iframe tag and sample code can be found on GitHub.
Web apps can now take advantage of Flutter’s fragment shader support, enabling the use of shaders for enhanced visual effects.
