Even more good news. I’ve gotten the tutorial to operate in an Android emulator on my Mac. After all the updates, including an update to the Android emulator, I was able to launch the emulator as a Pixel 2 XL running Android 7.1 (API 25). Interestingly enough I couldn’t configure an emulator using any of the Pixel 3 smartphone’s; there were none in the AVD manager. The Apple emulator, by contrast, has the latest iPhone XS and XR variants. But at least it works and validates Flutter’s claim that the same application developed in Flutter will run on both iOS and Android.

One quirk getting this to run. When I opened the tutorial back up, VS Code flagged the import of english_words.dart package. I had to re-run ‘flutter packages get’ in the tutorial folder and then restart VS Code. After that it was satisfied.
