Ability to render html in widget

[Martin Spriggs]

I'm considering switching to Flutter from Ionic/Angular but mostly deal with JSON content from a Wordpress site that gives me HTML to render. If I'm reading the docs correctly it looks like there is no way to take raw HTML content received via JSON and render that on screen? Thanks in advance!

We already support linking to a full screen html/browser via the url_launcher plugin. We unfortunately do not yet support an inline webview (see issue #730).

HTML is a giant spec with lots of crazy bits.  However, it should be possible to write some very basic html rendering in a Flutter widget following the patterns used in https://github.com/flutter/flutter_markdown.  I've not seen anyone do that yet however.

Even once we add inline webview support: https://github.com/flutter/flutter/issues/730 it will still be much more efficient to do simple HTML with something more akin to flutter_markdown.

I'm sure there would be a lot of demand for such a package were someone to write one. ;)

I've done something similar in wiki-flutter, since wikipedia's API also gives only html segments.

Here's a simple html parser, which consumes HTML and emits flutter widgets, via the dart `html` lib.

https://github.com/namiwang/wiki-flutter/blob/master/lib/views/shared/html_parser.dart

All you have to do is recursively travers the DOM tree and build widgets.

You've to set some custom rules, like <p>/<div> -> RichText, and consider how to handle line breaks.

The performance is bad, you get the idea though.
