MultipartRequest class

A multipart/form-data request.

Such a request has both string fields, which function as normal form fields, and (potentially streamed) binary files.

This request automatically sets the Content-Type header to multipart/form-data. This value will override any value set by the user.

var uri = Uri.https('example.com', 'create');
var request = http.MultipartRequest('POST', uri)
  ..fields['user'] = 'nweiz@google.com'
  ..files.add(await http.MultipartFile.fromPath(
      'package', 'build/package.tar.gz',
      contentType: MediaType('application', 'x-tar')));
var response = await request.send();
if (response.statusCode == 200) print('Uploaded!');
