If I want to run a single check function that is run before the code is evaluated, I place it in a code chunk whose label is suffixed with -code-check per #2. I'd like this to be a sufficient signal to learnr to add a "Submit Button" to the exercise chunk. However, learnr does not do this (example below). To get the "Submit Button," I also need to add a non-empty chunk whose label is suffixed with-check.
Here is the output of the document that follows. Note the absence of a Submit Answer button.

title: "Issue #351"
output: learnr::tutorial
runtime: shiny_prerendered

```{r setup, include=FALSE}
library(learnr)
checker <- function(label, user_code, check_code, envir_result, evaluate_result, ...) {
list(message = check_code, correct = FALSE, location = "append")
}
tutorial_options(exercise.checker = checker)
```
## There is no submit answer button
### ...because I don't use a -check chunk in addition to my -code-check chunk
