@PeterWCox did you experience any issues with the import statement currently in the docs?
I have used this multiple times and never found issues. The other controls also seem to be importing in the same way

[PeterWCox]

@joelfmrodrigues Yeah I tried to use exactly the same code as the docs but I got the same error as described in Issue #1235.

Weirdly enough I did scaffold a fresh project just now as a test, and the current import statement does work (?)

@PeterWCox not really sure why it didn't work before, it always worked for me.
Maybe the version of some tool or package was different?

@PeterWCox can we close this PR without merging and get back to it if you (or someone else) find the issue again?
