Add additional information to selection

Is there an existing issue for this?

The question

I currently set my selection as a link like this:

quillController.formatSelection(LinkAttribute('https://www.test.de/user/$value'));

If applied to the text @123, this would result in this output:

<p><a href="https://www.test.de/user/123 " target="_blank">@123 </a></p>

I would now like to add additional classes, for example to also store an ID or an avatarUrl.

I tried this code

quillController.formatSelection(Attribute('id', AttributeScope.inline, asd));

but it always gives me the error

Unable to apply Style to leaf: {Attribute{key: link, scope: AttributeScope.inline, value: https://www.test.de/user/123 }, Attribute{key: id, scope: AttributeScope.ignore, value: asd}} 'package:flutter_quill/src/models/documents/nodes/leaf.dart': Failed assertion: line 31 pos 12: 'value.isInline || value.isIgnored || value.isEmpty'

Any help would be appreciated.

Which version are you using?

This is such as an issue that i had with an old version (9.3.13).

This happen because leaf just validate the attributes into the package (harcoded), and the custom attributes, aren't taked as a valid Attribute. But, this is solved at the current version.

Thank you very much for your answer.

I updated the package and the error is gone now, but the output still has not changed.

Instead of

<p><a href="https://www.test.de/user/123 " target="_blank">@123 </a></p>

I would expect something like this:

<p><a href="https://www.test.de/user/123" target="_blank" id="asd">@123 </a></p>

Or is my code completely wrong here?

This is happening since you're not configure the vsc_quill_delta_to_html package. This package is used at this one, but, is limited on the documentation. I suggest use manually the package, or just passing your custom ConverterOptions and read the offical docs to render you custom attributes.

Here is vsc_quill_delta_to_html

vsc_quill_delta_to_html just apply the common attributes from Quill, but, the custom ones need to be implemented by the users
