Tracking screen views in Flutter with Firebase Analytics

Posted by Ramesh Singh | Updated on

Tracking screen views in Flutter with Firebase Analytics. The answer is: it depends. For a StatelessWidget, it might be suitable to have an Analytics event in build(), but only if the parent widgets are not re-built frequently. For a StatefulWidget the same applies but you also have to factor in re-builds due to state change (which are, more than likely often).

Really, the safest path is not to call Analytics events in any parts of the widget lifecycle, but instead on the UI event that might trigger a screen, for example, an edit button that opens up an edit screen. However, the problem with that approach is that the screen might be opened from a variety of locations within the app (meaning you have to duplicate Analytics calls across all those locations).
