Feature parity between Html and SelectableHtml

[jhass]

#169 got closed through #682 introducing a SelectableHtml with a feature subset currently achievable with Flutter's support level. Reaching feature parity is blocked by flutter/flutter#38474, but once this is resolved it would be nice to have a full implementation.

Yep, that is the plan once the Flutter issue is closed. #632 adds customRender back for SelectableHtml.

Alright, the Flutter PR adding support for widget span in editable text has been merged. We can't use it quite yet in the SelectableText (it's just a matter of removing an assert from the framework) but hopefully this should be coming soon and I will experiment with it. Currently they are working on how they want to do clipboard support.

We merged custtomRender support for SelectableHtml already into master and you can test it using flutter_html 3.0.0-alpha.2. There is no out-of-the-box feature parity though (notably images are not yet supported).

So this version doesn’t yet support images? Is that due to a flutter level bug still or something else?

[tneotia]

Correct, I experimented with the widget span support inside of selectable html, but there are quite a few issues with it that currently are still game-breaking. We could potentially support very simple use cases like images, videos, or audio, but any sort of container based formatting will still not be supported.

@erickok, I believe this is resolved in the latest flutter version, as flutter/flutter#38474 is now closed. Is that correct?

[tneotia]

We would need to explicitly add support for this in the package though. I experimented with it a few months back and it completely breaks text copy paste, so as I said in the previous comment container-based formatting should still not be supported.

[erickok]

Yes we can give it another go. Perhaps with Flutter 3 it is mature enough.

Any progress on this? Now that flutter has fixed the issue?
