Interface for working with analytic services. The library is supposed to unify work with various analytic services. The main actors are:

  • AnalyticAction — any action that is valuable for analytics. Usually it is a "button pressed" or "screen opened" type of event but the main criterion is a possibility to be handled by AnalyticStrategy.
  • AnalyticActionPerformer - an interface for analytic action performers. This class is an abstract base class for analytic strategies.
  • AnalyticStrategy — a class that provides a special way to send an analytical action. To create a custom analytic strategy, you should extend this class and implement the performAction method.
  • AnalyticService — a class that provides a way to send analytic action using a set of analytic strategies. To use this class, you should create an instance of it with a set of analytic strategies, and then call the performAction method to send analytic action.


The easiest interaction with the library is as follows:

  1. Determine the actions that ought to be recorded in the analytics service:

    class MyAnalyticAction implements AnalyticAction {
        final String key;
        final String value;
        MyAnalyticAction(this.key, this.value);
    class ButtonPressedAction extends MyAnalyticAction {
        ButtonPressedAction() : super("button_pressed", null);
    class ScreenOpenedAction extends MyAnalyticAction {
        ScreenOpenedAction({String param}) : super("screen_opened", param);
  2. Implement analytic strategy:

    class MyAnalyticStrategy
        extends AnalyticStrategy<MyAnalyticAction> {
        final SomeAnalyticsApi _analyticsApi;
        void performAction(MyAnalyticAction action) {
            _analyticsApi.send(action.key, action.value);
  3. Create an AnalyticService with your strategy:

    final analyticService = AnalyticService.withStrategies({




Add analytics to your pubspec.yaml file:

  analytics: $currentVersion$

At this moment, the current version of analytics is analytics version.

Migrating from 1.x.x to 2.x.x


    final analyticService = DefaultAnalyticService();

Starting from version 2.0.0, sending an event to a specific analytics service is implemented using strategies. The AnalyticService class stores these strategies. Implement analytics strategies using the AnalyticStrategy egy class.

    final analyticService = AnalyticService.withStrategies({
