Here Are The Key Features and Updates of Flutter 3.16

Material 3: A Fresh, Modern Look for Flutter Apps

One of the most notable changes in Flutter 3.16 is the adoption of Material 3 as the default theme. This latest iteration of Google’s design system introduces a refreshed and refined visual language, characterized by bolder typography, more vibrant colors, and enhanced accessibility features. With Material 3 as the default, developers can effortlessly create modern and visually appealing apps that adhere to Google’s latest design guidelines.

  • A new color palette: Material 3 introduces a new color palette that is more vibrant and expressive than the previous palette.
  • More typography options: Material 3 offers a wider range of typography options to give your apps a more polished look.
  • New animation patterns: Material 3 introduces new animation patterns that make your apps more responsive and engaging.

With Material 3 as the default theme, Flutter apps are now more visually appealing than ever before.

Impeller Preview for Android

Flutter 3.16 introduces an exciting preview of Impeller, a new rendering engine for Flutter on Android. Impeller promises significant performance improvements, particularly on lower-end devices, by utilizing a hardware-accelerated rendering pipeline. This preview marks a significant step forward in Flutter’s rendering capabilities and opens up new possibilities for Android application development.

DevTools Extensions

Flutter 3.16 expands the capabilities of the Flutter DevTools by enabling the development of extensions. These extensions can provide additional functionality and insights into Flutter apps, further enhancing the debugging and development experience. This feature empowers developers to create custom tools tailored to their specific needs and preferences.

Scrolling Updates: Smooth, Performant Scrolling Experiences

The 2D scrolling foundation in Flutter has been updated to support KeepAlive widgets, default focus traversal, and implicit scrolling. This makes it easier to create smooth, performant scrolling experiences for your users.

KeepAlive widgets allow you to keep content in memory as it scrolls off the screen. This can improve performance by avoiding the need to re-create the content when it scrolls back into view.

Default focus traversal allows you to easily navigate through your app using the keyboard. This is especially useful for users who rely on assistive technologies.

Implicit scrolling allows you to scroll content by dragging anywhere on the screen. This is a more natural and intuitive way to scroll than using a scrollbar.

Casual Games Toolkit Updates: Physics Simulation, Particle Effects, and More

The Flutter Casual Games Toolkit has been updated with a number of new features and improvements, including support for physics simulation, particle effects, and more.

Additional Flutter 3.16 Features and Updates

Alongside the major highlights, Flutter 3.16 brings a host of additional features and improvements, including:

  • WidgetScope rebuild performance: Optimized rebuild behavior for WidgetScopes, resulting in improved performance for complex widget trees.
  • TextScaleFactor updates: Enhancements to the TextScaler class, making it easier to adapt text sizes across different device configurations.
  • Tooling improvements: Updates to the Flutter toolchain, including performance enhancements and bug fixes.


Flutter 3.16 marks a significant step forward in the evolution of Flutter, solidifying its position as a powerful and versatile framework for cross-platform app development. With the introduction of Material 3, the Impeller preview for Android, DevTools extensions, and enhanced scrolling, Flutter 3.16 empowers developers to create high-performance, visually appealing, and modern apps for a wide range of devices and platforms. As Flutter continues to evolve, developers can expect even more exciting features and updates that will further revolutionize Flutter app development.

Flutter developers are in high demand due to the framework’s popularity and its ability to create high-quality apps quickly and efficiently.
