Impeller: A Rising Star in Rendering

Flutter 3.22 focuses heavily on the Impeller rendering engine, aiming for smoother visuals and better app performance. Here are the key highlights:

  1. Vulkan Backend on Android: The Vulkan backend is now complete for Android, leading to sharper graphics and noticeable performance improvements in your Android apps.
  2. Optimized Blur and Path Rendering: Impeller's ongoing optimizations for blur effects and complex path rendering result in a more visually appealing and fluid user experience.
  3. Experimental Testing API: A new experimental API for testing with Impeller is now available, helping developers explore Impeller's capabilities and streamline their testing process.
  4. Future Plans: The roadmap includes completing the iOS migration and expanding Android support, making Impeller a core component of Flutter's rendering capabilities.

WebAssembly (Wasm) in Stable Release

WebAssembly (Wasm) support has reached a stable stage in Flutter 3.22, bringing exciting possibilities for developers:

  1. Cross-Platform Code Sharing: Wasm enables seamless code sharing between web and mobile platforms, speeding up development and reducing code duplication.
  2. Native Code Integration: Developers can integrate existing libraries and functionalities into their Flutter apps using Wasm, leveraging the power of native code.
  3. Performance Boosts: Wasm offers performance benefits for computationally intensive tasks, further optimizing web apps.

Smoother Firebase Integration

Flutter 3.22 includes crucial updates for Firebase integration:

Resolved Issues: All known Firebase issues within Flutter have been resolved, ensuring smoother integration of Firebase functionalities into your Flutter apps.

Vertex Shaders: Unlocking New Graphics Potential

Vertex shaders are now supported in Flutter, allowing developers to:

  1. Fine-Tune Graphics: Vertex shaders provide fine-grained control over the manipulation of vertices, enabling the creation of more complex and visually interesting graphics.
  2. Advanced Effects: With vertex shaders, developers can create advanced graphical effects like custom lighting models and post-processing filters, enhancing app visuals.

Platform-Specific Enhancements for Android and iOS

Flutter 3.22 includes improvements specific to each platform:

  1. Android: The completion of the Vulkan backend on Android is a major highlight, along with other ongoing optimizations.
  2. iOS: While the iOS migration to Impeller is still on the roadmap, developers can expect continued refinements and bug fixes for the iOS platform.

Framework Updates for Easier Development

The Flutter framework itself has received valuable updates in version 3.22:

  1. Improved Documentation: The Flutter documentation now includes a new section on adaptive and responsive design, helping developers create apps that work seamlessly on different screen sizes and devices.
  2. Enhanced Developer Experience: New resources guide developers at various stages of their Flutter journey, including "what's next" advice for those who have completed the initial Flutter codelab, updated installation instructions, and new codelabs.
  3. Flavour-Based Asset Bundling: Developers can now bundle assets conditionally based on flavors, giving them more control over app size and resource distribution.
  4. Stable Wasm Support: As mentioned earlier, Wasm support is now stable, enabling developers to confidently use this technology for cross-platform development.
  5. Deep Link Validation in DevTools: A new screen in DevTools helps developers test deep links on Android devices, ensuring their app handles deep links correctly.
  6. Complimentary Dart 3.4 Features: The update coincides with Dart 3.4, which introduces functionalities like the built-in JsonCodable macro, streamlining data serialization processes in your Flutter apps.
  7. Form Validation Improvements: A new form validation method simplifies form handling in Flutter 3.22, making it easier to ensure user-provided data adheres to specific criteria.


Flutter 3.22 is a big update with lots of new features for developers. The improvements to the Impeller engine, the addition of WebAssembly, and the tweaks for Android and iOS all make Flutter a better tool for building apps. The updates to the framework also make development easier and more enjoyable.
