Flutter, Dart, and WASM: Shipping a new model for Web applications by Kevin Moore @ Wasm I/O 2024

Wasm I/O 2024 / 14-15 March, Barcelona

Now that garbage collection is a standard feature in the WebAssembly runtimes in Chromium-based browsers and Firefox, there is an opportunity for a wide variety of existing GC-languages to target Wasm. Learn how the Dart and Flutter teams and Google worked to add support for this new language to our existing web support, while maintaining compatibility with existing JavaScript. Supporting compilation to both Wasm and Javascript was a challenge. We will cover how JS-interop and browser APIs evolved along with our support for multi-threaded rendering. We’re also excited to showcase our performance compared to JavaScript in the browser and even native code.

The dream is getting closer and closer to being realized. #flutter #web

Great Talk Kevin! Flutter is the best Wasm UI Framework!!

[isaactfa]

Great speaker. Did not expect a Pitch Meeting reference. Tight.

Is it just me or is it that anytime the dotnet team speaks about WASM, people are generally angry. But when another framework discusses it, it's accepted as a revolutionary tech.

Waiting for this since an Year. He is evloved now like a Pokemon

[DevLife]

Great job Kev, really excited for the Flutter/WASM future

[chaitanyadamarasingu]

WE wanted performance over WEB and over power react js

4:37 Are you going to use a matrix for the logic in the next verision 🤣

[JT-mrdb]

Wonder how accessibility works if everything is just canvas rendered.

[ajitsinghyadav]

Google is that hard to have SEO friendly web/website app in Flutter 😢

[oleh]

Question to speaker. Can we expect dart isolates in web after migration to Wasm? I can compile multithreading C++ code to Wasm, why I can't compile multithreading dart code?

[rolf]

Oh yeah, that's going to be great for ads, unblockable as hell and event more intruse.

I see what u did there.

Btw, the speech was tight.

[chaitanyadamarsingu]

Wanted a real-time comparison of the renderers rather than just slides team... Flutter

[chaitanyadamarasingu]

there is no WEB APP for Superlist i guess

[chaitanyadamarsingu]

If not html renderer forget about mid-range mobile devices from opening flutter web app

[AMarenko]

Every single time I hear Flutter pitch speech stuffed with benchmarks putting Flutter in a spotlight, I swear, every single time I immediately follow one of the example app links and end up with a janky app with terrible UX. Oh, let me try this text input field - keyboard appears and app yeets you to another dimension and text input is nowhere to be seen. I'm talking about Material 3 app mentioned on the slides. I love Dart lang, I'd really love using it for web development, but this whole "Flutter for web" narrative is just one big lie.

I am sorry but Flutter makes no sense in the web why use something else when JavaScript is the web standard Flutter is great for mobile that s it
