Adding a development Proxy and dedicated Web configuration File

Flutter's current web development configuration relies on CLI arguments and does not have a development proxy. This PR adds a development proxy to flutter and a designated web_dev_config.yaml where web configuration settings are loaded from.

I'm very intestered so I'd like to give it a try but the basic example throw an error :

server:
  proxy: 
    - target: "https://localhost:3000"
      source: "/api/"

[ProxyRule] Invalid proxy rule in YAML: {target: https://localhost:3000, source: /api/}

The linked DOC seems outdated

mdebbar · 2025-08-11T14:02:32Z

@woprandi I'm assuming you are referring to the Google Doc, which is supposed to be a design doc and not final documentation.

Before this goes into a stable flutter release, we'll write official documentation for it.

For now, you can change source to prefix.

This also tells me we can improve on the error message to point users like yourself in the right direction 🙂
