argument for disable browser CORS policy

[amreniouinnovent]

I wonder if we could get an argument for disabling CORS Policy for debugging purposes until the backend developer whitelisted the domain and the port?

When I started to test my Android app if it will work on Flutter web or not I got the CORS issue.
I think it would be nice for first-time developers trying the mobile code to work on the web so maybe disable CORS would help to investigate the web-behavior.

{
	"name": "Flutter",
	"request": "launch",
	"type": "dart",
	"args": ["--no-cors", "true"]
}

My proposal rejected in Flutter but I hope it to get accepted here
flutter/flutter#46904

That would be great! We are currently running a proxy server in front of the webdev to be able to test our app locally (we have a Java backend and a Dart frontend and we can't load it with CORS).

Run the chrome while disabling CORS by https://stackoverflow.com/questions/3102819/disable-same-origin-policy-in-chrome

What is the frontend dart framework you are using ? is it Angular Dart?

[wytrych]

We're just using vanilla dart, home-built framework. Yeah I know about disabling CORS in chrome, but you can't do that in Safari which we need to support as well.

[wytrych]

Well actually seems like Safari does have "Disable CORS" in the Develop menu...

It's frustrating having to disable CORS on Chrome every. single. time.

This issue isn't relevant to this repro. We no longer build Flutter Web applications with package:webdev.

What about AngularDart?
