@import does not work in when create shiny app with golem

[Lev_ani]

I want to create shiny app with golem, but @import does not work and packages are not available when I want to run app.

I use following code in 02_dev.R:

...
usethis::use_package( "shinydashboard" )
...

and following one in app_ui.R:

#' @import dashboardthemes
#' @import shinydashboard
#' @import assertr
#' @import DT
#' @export
#' 

but when I use load_all() and then run_app() I get following error:

could not find function "dashboardPage"

What I do incorrectly and how to handle it?

Have updated your NAMESPACE ?
I would recommend using attachment::att_amend_desc()regularly (to avoid having to think about namespace and description).
Then please try again.

thank you @statnmap ; I have not updated NAMESPACE yet. I will try it.
