Getting started

You should ensure that you add the router as a dependency in your flutter project.

dependencies:
 algolia: ^1.1.2

You should then run flutter packages upgrade or update your packages in IntelliJ.

Example Project

There is a pretty sweet example project in the example folder. Check it out. Otherwise, keep reading to get up and running.

Setting up

  ///
  /// Initiate static Algolia once in your project.
  ///
  class Application {
    static final Algolia algolia = Algolia.init(
      applicationId: 'YOUR_APPLICATION_ID',
      apiKey: 'YOUR_API_KEY',
    );
  }
  
  void main() async {
    ///
    /// Initiate Algolia in your project
    ///
    Algolia algolia = Application.algolia;

    ///
    /// Perform Query
    ///
    AlgoliaQuery query = algolia.instance.index('contacts').query('john');

    // Perform multiple facetFilters
    query = query.facetFilter('status:published');
    query = query.facetFilter('isDelete:false');

    // Get Result/Objects
    AlgoliaQuerySnapshot snap = await query.getObjects();

    // Checking if has [AlgoliaQuerySnapshot]
    print('Hits count: ${snap.nbHits}');

    ///
    /// Perform Index Settings
    ///
    AlgoliaIndexSettings settingsRef = algolia.instance.index('contact').settings;

    // Get Settings
    Map<String, dynamic> currentSettings = await settingsRef.getSettings();

    // Checking if has [Map]
    print('\n\n');
    print(currentSettings);

    // Set Settings
    AlgoliaSettings settingsData = settingsRef;
    settingsData = settingsData.setReplicas(const ['index_copy_1', 'index_copy_2']);
    AlgoliaTask setSettings = await settingsData.setSettings();

    // Checking if has [AlgoliaTask]
    print('\n\n');
    print(setSettings.data);

    // Pushing Event
    AlgoliaEvent event = AlgoliaEvent(
      eventType: AlgoliaEventType.view,
      eventName: 'View contact',
      index: 'contacts',
      userToken: 'user123',
    );
    await algolia.instance.pushEvents([event]);
  }

Insights

The Insights API lets you push a collection of events related to how your product is being used. Sending those events is a required step for using several Algolia features like Click analytics, A/B Testing, Personalization and Dynamic Re-Ranking.

• .pushEvents(List<AlgoliaEvent> events)
