  • Material Design 3 support: Flutter 3.0 now includes support for Material Design 3, the latest version of Google’s design language. This includes new widgets, colours, and typography.
  • Web app Lifecycle API: The new Web app Lifecycle API gives developers more control over the bootstrap process of their Flutter web apps. This can be useful for things like loading background resources or handling navigation.
  • Raster cache: The raster cache has been improved in Flutter 3.0, which can lead to faster loading times for images.
  • FFI plugins: FFI plugins allow Flutter developers to call native code from their Flutter apps. This can be useful for things like accessing hardware APIs or integrating with existing codebases.

Other improvements: Flutter 3.0 also includes a number of other improvements, such as better performance, new tooling, and more.

Material Design 3 Support 

Material Design 3 is the latest version of Google’s design language, and it brings a number of new changes to the way that Flutter apps look and feel. Some of the key changes include:

  • A new colour palette with more vibrant colours.
  • A new typography system with more expressive fonts.
  • New widgets for creating more dynamic and interactive user interfaces.

Webapp Lifecycle API 

The Web app Lifecycle API gives developers more control over the bootstrap process of their Flutter web apps. This can be useful for things like:

  • Loading background resources before the app is visible to the user.
  • Handling navigation between different pages in the app.
  • Responding to changes in the browser’s window or tab.

The Web app Lifecycle API is still under development, but it is a powerful tool that can be used to create more sophisticated Flutter web apps.

Raster Cache 

The raster cache is a feature of Flutter that stores images in memory after they have been loaded once. This can improve the performance of Flutter apps by reducing the amount of time it takes to load images.

In Flutter 3.0, the raster cache has been improved to make it even faster and more efficient. This means that Flutter apps can now load images even faster than before, leading to a better user experience.

FFI Plugins 

FFI plugins allow Flutter developers to call native code from their Flutter apps. This can be useful for things like:

  • Accessing hardware APIs, such as the camera or the microphone.
  • Integrating with existing codebases that are written in other languages, such as Java or Objective-C.
  • Writing Flutter apps that are more performant and secure.

FFI plugins are still under development, but they are a powerful tool that can be used to create more sophisticated Flutter apps.

Other Improvements 

In addition to the features mentioned above, Flutter 3.0 also includes a number of other improvements, such as:

  • Better performance on all platforms.
  • New tooling, such as a new debugger and a new performance profiler.
  • Improved support for internationalisation and accessibility.

Overall, Flutter 3.0 is a major release that includes a wide range of new features and improvements. If you’re a Flutter developer, I encourage you to check out Flutter 3.0 and see what’s new. If you’re new to Flutter, I encourage you to give it a try. Flutter is a powerful and versatile framework that can be used to build beautiful, high-performance apps for a variety of platforms.
