sendChunkedMessageText method Null safety

Future<SmtpResponse> sendChunkedMessageText(
  1. String text,
  2. MailAddress from,
  3. List<MailAddress> recipients,
  4. {bool use8BitEncoding = false}
)

Sends the specified message text from to the recipients using the BDAT SMTP command.

BDATA is supported when the SMTP server announces the CHUNKING capability in its EHLO response. You can query SmtpServerInfo.supportsChunking for this. In contrast to the other methods the text is not modified apart from the padding of <CR><LF>.<CR><LF> sequences. Set use8BitEncoding to true for sending a UTF-8 encoded message body.

Implementation

Future<SmtpResponse> sendChunkedMessageText(
    String text, MailAddress from, List<MailAddress> recipients,
    {bool use8BitEncoding = false}) {
  if (recipients.isEmpty) {
    throw SmtpException(this, SmtpResponse(['500 no recipients']));
  }
  return sendCommand(SmtpSendBdatMailTextCommand(
      text, use8BitEncoding, from, recipients.map((r) => r.email).toList()));
}
