dvHomeWidgetAppGroup function
The App Group the application and its widget extension share on Apple platforms, derived from the application's own bundle id.
Per application for the reason an Android provider authority is: a constant here means the second Dartvel application installed reads the first one's container, or is refused the entitlement and shows a placeholder nobody can explain.
Implementation
String dvHomeWidgetAppGroup(String bundleId) =>
'group.$bundleId.dartvelwidgets';
