Error connecting: Unsupported operation: Socket constructor (WASM)

[flrnsbt]

While running a Flutter Web app build in WASM, I get this runtime error: 'Error connecting: Unsupported operation: Socket constructor'. Working fine in javascript, I'm using gRPC web of course.

4.0.0

Repro steps

1. Create a new Flutter web project that uses gRPC web
2. Build it in wasm and launch the app-
   Expected result: gRPC calls to work properly

Actual result: It seems that the wrong Socket constructor is used, instead of using a web compatible one, when we build in WASM
