Google I/O 2024 announced about  WebAssembly support for Flutter. 

What is WebAssembly?

WebAssembly (shortened to Wasm) is like a special language that computers can understand quickly. It works with a virtual machine that's built like a stack of instructions. Wasm is made so that different programming languages can easily turn their code into it. This makes it easy to use on the internet for both client-side and server-side programs.

Here is our Lanka Tik flutter version, where we try to build a wasm version. 

As the Google Team introduced this in the stable version of Flutter 3.4, we hope it is stable and can start with 
production build.
