Hi everybody.

The buttons in the AboutDialoog seem to be using the default colors and ignore coloring themes defined higher up.
On Android, this results in "View Licences" and "Close" buttons in some shade of cyan (I believe this is the default Material accentColor).
On iOS, it results in standard blue buttons and a blue AppBar on the "Licences" page when clicking the "View Licences" button.

I'm grateful for any hints on how to work around this.
