read function
Sends an HTTP GET request with the given headers to the given URL and returns a Future that completes to the body of the response as a String.
The Future will emit a ClientException
if the response doesn't have a
success status code.
This uses the shared HttpPlusClient.defaultClient instance for making HTTP requests.
For more fine-grained control over the client, create and use HttpPlusClient directly.
Implementation
Future<String> read(Uri url, {Map<String, String>? headers}) =>
HttpPlusClient.defaultClient.read(url, headers: headers);
