void setContentType(MediaType mediaType, { CharacterSet? characterSet, String? multiPartBoundary, String? name, Map<String, String>? parameters, })

Implementation

void setContentType(
  MediaType mediaType, {
  CharacterSet? characterSet,
  String? multiPartBoundary,
  String? name,
  Map<String, String>? parameters,
}) {
  if (mediaType.isMultipart && multiPartBoundary == null) {
    // multiPartBoundary is null and this is a multipart ->
    // define a default boundary:
    // ignore: parameter_assignments
    multiPartBoundary = MessageBuilder.createRandomId();
  }
  final contentType = ContentTypeHeader.from(
    mediaType,
    charset: mediaType.top == MediaToptype.text
        ? MessageBuilder.getCharacterSetName(characterSet)
        : null,
    boundary: multiPartBoundary,
  );
  if (name != null) {
    contentType.parameters['name'] = '"$name"';
  }
  if (parameters != null && parameters.isNotEmpty) {
    contentType.parameters.addAll(parameters);
  }
  this.contentType = contentType;
