Uint8List attachments

[biancashouse]

I generate pdfs dynamically, and they are Uint8List.
I can't figure out if it is possible to send them (base64encoded?) to the sendinblue api.
Any guidance would be appreciated.
You send files as attachments, so I guess it must be possible ?
Thanks in advance

There is a StreamAttachment class:

I haven't programmed in dart for quite some time. Can you convert the Uint8List to a Stream<List<int>>?

class StreamAttachment extends Attachment {
  final Stream<List<int>> _stream;

  StreamAttachment(this._stream, String contentType, {String? fileName}) {
    this.contentType = contentType;
    this.fileName = fileName;
  }

  @override
  Stream<List<int>> asStream() => _stream;
}

Please reopen, if this doesn't solve your problem.

Quite right. Works well. Many thanks. Since flutter web requires CORS headers, I would remove the "web" tick, and instead inform the user they should use a server for sending from web apps. I now use mailer in a Google Cloud Run function. so I can use it from mobile and web. I guess it's more secure anyway, because it avoids having to embed api keys in the app (Google Secrets API)

This library doesn't work in flutter web. It's technically just not possible.

Is there a way to mark the library unsuitable for flutter web?

In actual fact, I think you will find some companies, such as ClickSend, don't require CORS headers with their API key, so perhaps that is why flutter web is checked. It's safer to assume that such companies will eventually close that loophole. A real benefit to moving your email send function to a server is that your API key won't be embedded in your mobile or web app.
