home_widget interactive callback not triggered

Discussed in #323

^{Originally posted by avorio-dev January 4, 2025}
Hello,
I'm having an issue with the home_widget package, specifically with the interactiveCallback function. Once the refresh icon is pressed in my widget, I want it to update the data using the appropriate method in my Flutter class. I don't understand why the event is not triggering. Please, could you provide any suggestions?

Below, there is my code. What I expect is the trigger of backgroundCallback: Anyway, the normal update of elements in my widget is correct. Only the background callback not working

Manifest.xml

<receiver
    android:name=".MyAppHomeWidget"
    android:exported="true">
    <intent-filter>
        <action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
    </intent-filter>

    <meta-data
        android:name="android.appwidget.provider"
        android:resource="@xml/my_home_widget_info" />
</receiver>


<!-- Used for Background Work -->
<receiver
    android:name="es.antonborri.home_widget.HomeWidgetBackgroundReceiver"
    android:exported="true">
    <intent-filter>
        <action android:name="es.antonborri.home_widget.action.BACKGROUND" />
    </intent-filter>
</receiver>
<service
    android:name="es.antonborri.home_widget.HomeWidgetBackgroundService"
    android:exported="true"
    android:permission="android.permission.BIND_JOB_SERVICE" />

Kotlin

class MyAppHomeWidget : HomeWidgetProvider() {
    override fun onReceive(context: Context?, intent: Intent?) {
        super.onReceive(context, intent)
    }

    override fun onUpdate(
        context: Context,
        appWidgetManager: AppWidgetManager,
        appWidgetIds: IntArray,
        widgetData: SharedPreferences
    ) {

        appWidgetIds.forEach { appWidgetId ->
            val views = RemoteViews(context.packageName, R.layout.my_app_home_widget).apply {

                // Open App on Widget Click
                val openAppOnClickIntent =
                    HomeWidgetLaunchIntent.getActivity(context, MainActivity::class.java)
                setOnClickPendingIntent(R.id.widget_container, openAppOnClickIntent)

                // Swap Title Text by calling Dart Code in the Background
                val refreshDataIntent =
                    HomeWidgetBackgroundIntent.getBroadcast(
                        context, Uri.parse("myHomeWidget://updateLocationAndForecast")
                    )
                setOnClickPendingIntent(R.id.refreshDataIcon, refreshDataIntent)

                // Update widget data
                setTextViewText(
                    R.id.widgetLocation,
                    widgetData.getString("widgetLocation", "Somewhere")
                )
                setTextViewText(
                    R.id.widgetWeatherCondition,
                    widgetData.getString("widgetWeatherCondition", "Unknown")
                )

                setTextViewText(
                    R.id.widgetTemperature,
                    widgetData.getString("widgetTemperature", "N/A")
                )
                setTextViewText(R.id.widgetHumidity, widgetData.getString("widgetHumidity", "N/A"))
                setTextViewText(R.id.widgetRainProb, widgetData.getString("widgetRainProb", "N/A"))
                setTextViewText(R.id.widgetWind, widgetData.getString("widgetWind", "N/A"))

                setTextViewText(
                    R.id.widgetLastUpdateDate,
                    widgetData.getString("widgetLastUpdateDate", "N/A") ?: "No Title Set"
                )

                //setTextViewText(R.id.widgetLastUpdateDate, widgetData.getString("widgetLastUpdateDate", "Unknown"))
            }

            appWidgetManager.updateAppWidget(appWidgetId, views)
        }
    }

    override fun onEnabled(context: Context) {
        // Enter relevant functionality for when the first widget is created
    }

    override fun onDisabled(context: Context) {
        // Enter relevant functionality for when the last widget is disabled
    }
}

Dart

class HomeWidgetController {
  static const String _classname = 'HomeWidgetController';

  /// Called when Doing Background Work initiated from Widget
  @pragma("vm:entry-point")
  static Future<void> backgroundCallback(Uri? data) async {
    AppLogger.info(_classname, 'App Widget call with URI: $data');
    if (data?.host == 'updateLocationAndForecast') {
   
    
    }
  }

  static Future<void> initialize() async {
    HomeWidget.setAppGroupId(GlobalVar.widgetGroupId);
    await HomeWidget.registerInteractivityCallback(backgroundCallback);

  }
}

the method initialize is called in main.dart as follow:

WidgetsFlutterBinding.ensureInitialized();
await HomeWidgetController.initialize();
```</div>

Hey @avorio-dev and @Atikur-Rahman-Sabuj moved the discussion in a separate issue.

Can you please provide:

• Flutter Version
• Android Version
• Confirm which Version of home_widget you are using. Please try with the latest version (0.7.1)
