og:image meta tags for my dynamic pages

I am looking to add meta information so that links to my app can have custom titles and images when Sharing them through social media. Currently I only managed to have the Title of the App above the shared link.

you can add meta tags by implementing the configurePage method of your AppShellConfigurator implementor class

there is no clear way to get RouteParameters to publish dynamic meta info, any ideas?

For more advanced use cases you might consider an IndexHtmlRequestListener

IIRC the method to implement gets an object that let you access the current request and then modify the html Dom structure
