Analytics

Overview

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.

Example

The easiest interaction with the library is as follows:

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);
}

Implement analytic strategy:

class MyAnalyticStrategy
    extends AnalyticStrategy<MyAnalyticAction> {
    final SomeAnalyticsApi _analyticsApi;

    SomeAnalyticsApi(this._analyticsApi);

    @override
    void performAction(MyAnalyticAction action) {
        _analyticsApi.send(action.key, action.value);
    }
}

Create an AnalyticService with your strategy:

final analyticService = AnalyticService.withStrategies({
    MyAnalyticStrategy(analytics),
});

Usage:

    analyticService.performAction(ButtonPressedAction());

Installation

Add analytics to your pubspec.yaml file:

dependencies:
  analytics: $currentVersion$

At this moment, the current version of analytics is .

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

1.x.x

    final analyticService = DefaultAnalyticService();
    analyticService.addActionPerformer(
        MyAnalyticActionPerformer(SomeAnalyticService()),
    );

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({
        MyAnalyticStrategy(analytics),
    });
