contentType property
Implementation
String? get contentType => _headers[Headers.contentTypeHeader] as String?;
The request Content-Type. The default value is ContentType.json.
If you want to encode request body with 'application/x-www-form-urlencoded',
you can set ContentType.parse('application/x-www-form-urlencoded')
, and Dio
will automatically encode the request body.
Implementation
set contentType(String? contentType) {
if (contentType != null) {
_headers[Headers.contentTypeHeader] =
_defaultContentType = contentType.trim();
} else {
_defaultContentType = null;
_headers.remove(Headers.contentTypeHeader);
}
}
