Unable to load source maps when dart web project is not hosted in root folder.

Hi Team,

Our team migrated from the Google web tool kit to Dart recently.
Where

• v1 folder is legacy web project build using GWT framework
• v2 folder is migrated web project using Dart SDK.

Our web server hosts both versions from different folder paths.
We were trying the source mapping feature supported by webdev using command 'webdev build --no-release'

Unfortunately, the scripts were not imported properly due to the invalid import file path set by bootstrap.js & require.js.
On further debugging, I understood the issue is because of the baseUrl function which returns "/" instead of expected "/v2".
Reading through the documentation, I found some suggestions related to adding <base href="/v2">, which do resolve the issue, but caused page routing and image loading issues.

I was able to resolve the issue by returning "/v2" by default instead of "/" in baseUrl Function of generated bootstrap.js and require.js.

Hence I request the team to add an new command line argument to set baseUrl of project.
Ex: webdev build --no-release --base-url="/v2"

Hi @anantha-krish! Thanks for the suggestion. We welcome community contributions for new features like this. If you open a PR for this, I am happy to review it.

Out of curiosity, are you using a web framework or pure Dart for your application?

Hi @elliette ,

It's better to be handled by a consistent webdev contributor. Please have a look at your free time, it will be a great help.
We are using pure Dart for our web project.
