[FEATURE] Allow to configure custom selection controls in SelectableHtml widget by exposing selectionControls property of SelectableText

[kirankumbhar]

Describe your feature request
For SelectableText() widget we have property called selectionControls to configure custom toolbar option. More about it here. Although, it is not trivial to implement a custom toolbar and this is less likely will be used, but I have a very specific use case where instead of copy, cut, paste options I need a highlight option to highlight selected text.

I'm ready to raise PR for the same. Let me know if this will be accepted or not.

Additional context
If anyone is interested in how custom toolbar will be implemented, you can refer to this example here
basically, we need to override MaterialTextSelectionControls class.

Puppy is looking for acceptance of feature 🐶

Well that sounds very useful. And why not accept that - it's a selectable widget so support for a custom toolbar sounds very reasonable. As long as it works with the text spans of all kinds. Thanks in advance!

Thank you!
I'll raise the PR. The only work in the library is to add selectionControls property for SelectableHtml widget which will be used by the underlying SelectabeText if provided.
