Hi.

Thank you for this amazing plugin.

Do you have examples of use of ContentBlocker?

I´m trying to use it for block content but I get errors.

This is my code:

contentBlockers: [
                        ContentBlocker(
                          trigger: ContentBlockerTrigger(
                            urlFilter: widget.url,
                          ),
                          action: ContentBlockerAction(
                            type: ContentBlockerActionType.CSS_DISPLAY_NONE,
                            selector: 'h1.title,div.site-trigger,div.leaderboard',
                          ),
                        ),
                      ],

And I get this exception:
