Getting started profiler #

Contextual Profiler SDK offers a comprehensive and efficient solution for collecting valuable information about your users. With this powerful tool, you will be able to gather relevant data that will allow you to conduct in-depth analysis and gain a clear understanding of your users' behavior, preferences, and needs.

See the full API for more methods.

Installation #

Please read this entire section.

add this lines in pubspec.yaml file under dependecies section #

profiler:
  git:

    ref: main

Android #

you MUST add this line to build.gradle (proyect)

allprojects {
    repositories {
        google()
        mavenCentral()
          maven {
            url "https://gitlab.com/api/v4/projects/58175283/packages/maven"
        }
    }
}

and in build.gradle (app)

    implementation 'com.fivvy:fivvy-lib:1.1.0@aar'

Permissions

AndroidManifest #

Necesary to add this xmlns:tools insde the tag manifest on AndroidManifest.xml insde android/app/src/main folder.

<manifest 
  <!-- Others manifest properties -->
  xmlns:tools="http://schemas.android.com/tools"
>

Need to add these permissions in the AndroidManifes.xml file inside android/app/src/main before aplication tag.

<manifest>
  <!-- others aplications tags -->
  <uses-permission  android:name="android.permission.INTERNET" />
  <uses-permission  android:name="android.permission.PACKAGE_USAGE_STATS"  tools:ignore="ProtectedPermissions" />

  <!-- List of apps that you want to check on customer device -->
  <queries>
    <!-- List of package's [Max 100] -->
    <package android:name="com.whatsapp"/> <!-- WhatsApp Messenger -->
    <package android:name="com.facebook.katana"/> <!-- Facebook -->
    <package android:name="com.mercadopago.android"/> <!-- Mercado Pago -->
    
  </queries>

  <application>
    <!-- ... -->
  </application>
</manifest>

Integration in App #

On android you must request permissions beforehand

Init of plugin #

First of all, you will need to instantiated previously the ContextualProfiler plugin on the Widget where you will use the methods.

import 'package:profiler/plugin/contextual_profiler.dart';

class MyHomePage extends StatefulWidget {
  const MyHomePage({super.key, required this.title});

  final String title;

  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  // ADD THIS LINE
  final _profilerPlugin = ContextualProfiler();

  // Your Code
}

Get user permission to check the app's usage #

This is an exclusive custom dialog that you can invoke in your app to get bring a easy way to request access usage permission from the user.

First you need to add a function to transform an image to a byte array.

Future<Uint8List> loadImageBytes(String assetPath) async {
    final ByteData data = await rootBundle.load(assetPath);
    return data.buffer.asUint8List(data.offsetInBytes, data.lengthInBytes);
  }

then implement this method: 
 Future<void> openAccessUsageSettings() async {
    String platformVersion;

       final Uint8List imageBytes = await loadImageBytes("assets/images/logo.png");


    final usageSetting = UsageSetting(
      language: "es",
      appName: 'Fivvy', // string value with your app name
       imagePath:
        imageBytes, // this image should be in android/app/src/main/res/drawable/logo.png
      appDescription: 'Activate the permission', // optional description text. Recommended length: 3 or 4 words
      modalText: 'Lorem ipsum text', // optional modal text. Recommended length: 3 or 4 words
      dialogTitle: "Dialog Title",  
      dialogMessage1: "Dialog message 1",
      dialogMessage2: "Dialog message 2"
    );
    try {
      await _profilerPlugin.openUsageAccessSettings(usageSetting);
      platformVersion = 'opened successfully';
    } on PlatformException {
      platformVersion = 'Failed to open Access Usage Settings.';
    }

    if (!mounted) return;

    setState(() {
      _response = platformVersion;
    });
  }

Another option #

However, there is a separate function in case you want to create a custom dialog that best suits your application. Consider having the ContextualProfiler [here as _profilerPlugin] plugin instantiated previously.

  Future<void> openAccessUsageSettingsDirectly() async {
    String platformVersion;
    try {
      await _profilerPlugin.openUsageAccessSettingsDirectly();
      platformVersion = 'opened successfully';
    } on PlatformException {
      platformVersion = 'Failed to open Access Usage Settings.';
    }

    if (!mounted) return;

    setState(() {
      _response = platformVersion;
    });
  }

Send data to Fivvy's analytics service #

This function will allow your app to send the information of each user to the Fivvy Analytic's API. You must add on some view or loading component that can send the data at least 1 time a day.

  Future<void> initContextualDataCollection() async {
    String response;

    ContextualCredential initConfig = ContextualCredential(
        customerId: customerId,
        apiPassword: apiSecret,
        apiUsername: apiKey,
        authApiUrl: authApiUrl,
        sendDataApiUrl: sendDataApiUrl);

    try {
      await _profilerPlugin.initContextualDataCollection(initConfig);
      response = 'Send data successfully';
    } on PlatformException {
      response = 'Something went wrong.';
    }

    if (!mounted) return;

    setState(() {
      this._response = response;
    });
  }
