http post a map object using application/json content-type

I am encountering a problem trying to use the "package:http/http.dart' pub package to post some JSON data to a web service. I have formatted the data correctly (which I confirmed by posting using the Advanced REST Client extension for Chrome) and the only difference is the Content-Type is forced to the wrong type (the web service only accepts "application/json"):

If body is a Map, it's encoded as form fields using encoding. The content-type of the request will be set to "application/x-www-form-urlencoded"; this cannot be overridden.

The documentation suggests:

For more fine-grained control over the request, use Request or StreamedRequest instead.

Why is the post content type limited to only form-urlencoded? Can the pub package be fixed to set the content type dynamically?

The auto-encoding of Maps for [body] is just utility functionality; it makes it easier to do the common case (sending form parameters) without cutting off other possibilities. You can always post arbitrary data by passing [body] a string or a List<int>. For example:

    http.post(url,
        body: JSON.encode(data),
        headers: {'content-type': 'application/json'}));
