Sending Pdf Attachment With Flutter

[Ulvi02]

I want to send a pdf document to email using EmailJS. I am directing pathfile of the pdf to the Dynamic Variable Attachment, but I am getting an unopenable pdf to my email. Thanks in advance

body: json.encode({
  'service_id': serviceId,
  'template_id': templateId,
  'user_id': userId,
  'template_params': {
    'name': ["('${path.path}/my_invoice.pdf')"],
    'user_email': [_user?.email ?? ''],
    'name_of': '',
  }
}

Is my_invoice.pdf file located on the server or generated on the device?
If it is created on the device, you have to send it as base64 URI.
