Hotwire Native for Rails Developers: navigatorHostId value (pages 28, 29, 30)
The first time the navigatorHostId
is set it uses the value R.id.main_nav_host
supposedly added to to activity_main.xml
in previous steps. But the id used for the fragment is main
not main_nav_host
.
First Post!

Thanks @ingilniero! This will be fixed in the next release.
