20210612

Now that we have the app functioning some simple edits to the app will tune it to suit our own preferences. Specifically we can edit lib/HomeScreen.dart. As an example, Indonesian was added to the languages, replacing Russian, and Australian English replaced US and UK English buttons The changes to lib/HomeScreen.dart included the following snippets:

                     if (_translatedTexts.isNotEmpty)
-                      speak('en-US', _translatedTexts[0]);
+                      speak('en-au', _translatedTexts[0]);
                   },
                 ),
...

After this change was made, typing R into the controlling console (where you ran flutter run) will hot restart the app.
