Hope v1.0.0 can set the whitelist of the elements

Set up the whitelist easier than the blacklist

[Sub6Resources]

For what use-case do you need a white list of elements?

[gzlock]

If just allow a, div, img three elements, now only the blacklist, so I need to set a huge list to arrived the same effect with the whitelist. The blacklist looks like ['span', 'h1', 'h2', 'h3', 'iframe', 'video', 'embed', 'ul', 'li'] The whitelist very simple, looks like ['a', 'div', 'img']

Unless we find other people supporting this, I doubt whether we will implement this. Not only can you blacklist elements you don't want (granted, a bit tedious) or sanitize the html yourself before feeding it to flutter_html (granted, a bit cumbersome), but the usage for an include list seems very small in scope.

I was just thinking about this - what if we exposed a getter with all the supported HTML tags to help with this. The implementation could look like this:

Html(
   tagsList: Html.tags.remove(/*tags to remove*/) or ['a', 'div', 'img']
);

The first case blacklists and the second case whitelists. This would be a breaking change though, but definitely not too hard to implement. I can't think of any caveats in my mind either (aside from users whitelisting unsupported tags but even then they would just be ignored right?)
