Generate html code from any email mime message for displaying it.

Usage

The enough_mail_html package defines the transformToHtml() extension method on MimeMessage of the enough_mail package.

This method will always generate HTML, specifically also for plain text or empty messages. You can define your custom processors

• for converting a plain text message into HTML,
• for adapting the HTML message,
• for handling inline attachments.

A simple usage example:

import 'package:enough_mail/enough_mail.dart';
import 'package:enough_mail_html/enough_mail_html.dart';

String generateHtml(MimeMessage mimeMessage) {
  return mimeMessage.transformToHtml(
        blockExternalImages: false, 
        emptyMessageText: 'Nothing here, move on!',
  );
}

String generatePlainText(String htmlText) {
  return HtmlToPlainTextConverter.convert(htmlText);
}

More examples:

import 'package:enough_mail/enough_mail.dart';
import 'package:enough_mail_html/enough_mail_html.dart';
import 'package:html/dom.dart';

String simpleTransformExample(MimeMessage mimeMessage) {
  return mimeMessage.transformToHtml();
}

String configureImageBlockingOrEmptyMessage(MimeMessage mimeMessage) {
  return mimeMessage.transformToHtml(
      blockExternalImages: true, emptyMessageText: 'Nothing here, move on!');
}

String playYourself(MimeMessage mimeMessage) {
  final cfg = TransformConfiguration.create(
      blockExternalImages: true,
      emptyMessageText: 'Nothing here, move on!',
      customDomTransformers: [StyleTextDomTransformer()],
      customValues: {'textStyle': 'font-size:10px;font-family:verdana;'},
  );
  return mimeMessage.transformToHtml(transformConfiguration: cfg);
}

class StyleTextDomTransformer extends DomTransformer {
  @override
  void process(Document document, MimeMessage message,
      TransformConfiguration configuration) {
    final paragraphs = document.getElementsByTagName('p');
    for (final paragraph in paragraphs) {
      paragraph.attributes['style'] = configuration.customValues['textStyle'];
    }
  }
}
