[web:tool] support -d web-server or equivalent way to serve a web app in a simple browser-agnostic way #120691
Description
Hi,
I'm developing a web application for a professional project. So far so good, but while implementing Datadog, I saw an error that was often seen on Firefox browser. I was interested in this one and I discovered a WebGL error.
Steps to Reproduce
- Create a Flutter web project and run on Firefox last version.
- Warning message
WEBGL_debug_renderer_info is deprecated in Firefox and will be removed. Please use RENDERER. [canvaskit.js:16:383](https://unpkg.com/[email protected]/bin/canvaskit.js)
- Error message
Error from backend:
Error: Bad state: Not connected to an application.
