Override the methods of the WluperPluginInterface to handle Errors, live text and end of speech event.

@override
void wluperOnError(String error){
// implement here your code
}

@override
void wluperOnLiveText(String text){
// implement here your code
}

@override
void wluperEndOfSpeech(){
// implement here your code
}

Declare WluperPluginFlutter object.

class _MyAppState extends State<MyApp> implements WluperPluginInterface {
...
WluperPluginFlutter wluperSDK = WluperPluginFlutter();
...

Initialise the SDK with the tu_api_key, log_api_key, client_id and the WluperPluginInterface listener.

Future<void> initPlatformState() async {
...
wluperSDK.init(this, _client_id, _tu_api_key, _log_api_key ).then((result) => /*implement here your code*/ );
...

Wrap plugin methods wluperSDK.startListening(), wluperSDK.understand() and wluperSDK.understand().

class _MyAppState extends State<MyApp> implements WluperPluginInterface {
...

void startListening(){
wluperSDK.startListening().then((result) => /*implement here your code*/);
}

void understand(text){
wluperSDK.understand(text).then((result) => /*implement here your code*/);
}

void cancelListening(){
wluperSDK.cancelListening().then((result) => setState(() => /*implement here your code*/);
}

...

Invoke the methods startListening(), understand(text) and cancelListening() from UI. While you speak, the live text is received by the listener wluperOnLiveText . The end of speech is detected automatically by the SDK and it is notified in the wluperEndOfSpeech callback (see point 4).

class _MyAppState extends State<MyApp> implements WluperPluginInterface{
String _status = 'Unknown';
String _tree = "";
String _error = "";
String _plain_text ="";
...
void cleanUI(){
setState(() {
_status = "";
_error= "";
_tree = "";
_plain_text = "";
});
}
...
