Parser crashes on entry-hyperlinks about contentful-rich-text-flutter

Yup, I would guess that null-checking the textNode.value prior to trying to call HtmlUnescape.convert() on it would potentially resolve the issue.

https://github.com/Kumanu/contentful-rich-text-flutter/blob/master/lib/contentful_rich_text.dart

184    String nodeValue = HtmlUnescape().convert(textNode.value);

Happy to accept a PR that updates that, or I'll try to address it. In the meantime I'd recommend not including the entry link if possible.

Disabling unsupported types is definitely planned, however I would still prefer if the parser wouldn't crash in case the configuration is off ;)

I'll create a PR with this check:

if (textNode.value == null) return TextSpan();

Would it be ok to also add the following block? That way links to entries would still be ignored, but at least the text would be output. Without it, the above would only output a blank line:

    // for links to entries only process the child-nodes
    if (node['nodeType'] == 'entry-hyperlink') {
      return TextSpan(
        children: node['content']
            .map<TextSpan>((subNode) => _processInlineNode(subNode) as TextSpan)
            .toList(),
      );
    }

Yup, I like the idea of keeping the text 👍
