31.27 Flutter Apps: Language Learning App Edit

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:

-                      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.
