31.21 Flutter App: Language Learning App Edit


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:

   List<String> _translatedTexts = [];
   List<String> _languagesCode = [

+    'id',

@@ -99,32 +99,22 @@ class _HomeScreenState extends State<HomeScreen> {

                     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.
