Support --route on flutter drive for Web

[fotiDim]

Use case

I want to run an integration test for flutter web where it opens a unknown route and checks for the 404 page.

flutter drive --target=test_driver/app.dart --no-headless --release --route '/password' lib/routes.dart

Proposal

On the web it seems to ignore the route parameter. On Android it works fine. I think this scenario makes way more sense on the web than on mobile since the user can type any URL in the search bar.

I would like to suggest expanding this issue to browser navigation in general.

I'm attempting to write a battery of driver tests that ensure that if the user enters a given URL after achieving an authenticated state in the app, the correct page is shown. For example: ensuring that a "sign up" page is not served if the user is already signed in. At present, I'm not sure how to write these tests, or if I can.

Ideally, I'd like a Driver API, or something similar that allows me to enter a desired URL at any moment in time as if it were typed into the address bar in the browser.

I'd like to add to this request and make sure that the --route parameter can be supported in the launch.json file. I'm developing a Flutter Web application and it would be nice to be able to have different configurations that I can select from the dropdown menu (see image below) that would launch with different query parameters in the URL.
