A Dart Client for Matomo. This is completely written in Dart and works cross-platform, including web.

dependencies:
    matomo: ^1.1.0

As early as possible in your application, you need to configure the Matomo Tracker to pass the URL endpoint of your instance and your Site ID.

    await MatomoTracker().initialize(
        siteId: siteId,
        url: 'https://example.com/piwik.php',
    );

If you need to use your own Visitor ID, you can pass it at the initialization of MatomoTracker as is:

    await MatomoTracker().initialize(
        siteId: siteId,
        url: 'https://example.com/piwik.php',
        visitorId: 'customer_1',
    );

To track views simply replace StatelessWidget by TraceableStatelessWidget, StatefulWidget by TraceableStatefulWidget and finally InheritedWidget by TraceableInheritedWidget.

You can also optionally call directly trackScreen or trackScreenWithName to track a view.

For tracking goals and, events call trackGoal and trackEvent respectively.

A value can be passed for events:

MatomoTracker().trackEvent('eventName', 'eventAction', eventValue='eventValue');

If you want to offer a way for the user to opt out of analytics, you can use the setOptOut() call.

MatomoTracker().setOptOut(true);
