// Track events
MostlyGoodMetrics.track("button_clicked")
MostlyGoodMetrics.track("purchase_completed", properties: [
    "product_id": "SKU123",

])

// Identify users
MostlyGoodMetrics.identify(userId: "user_123")

Android

import com.mostlygoodmetrics.sdk.MostlyGoodMetrics

// Initialize once in Application class
MostlyGoodMetrics.configure(this, "mgm_proj_your_api_key")

// Track events
MostlyGoodMetrics.track("button_clicked")
MostlyGoodMetrics.track("purchase_completed", mapOf(
    "product_id" to "SKU123",
    "price" to 29.99
))

// Identify users
MostlyGoodMetrics.identify("user_123")

React Native

import MostlyGoodMetrics from '@mostly-good-metrics/react-native';

// Initialize once at app startup
MostlyGoodMetrics.configure('mgm_proj_your_api_key');

// Track events
MostlyGoodMetrics.track('button_clicked');
MostlyGoodMetrics.track('purchase_completed', {
  product_id: 'SKU123',
  price: 29.99,
});

// Identify users
MostlyGoodMetrics.identify('user_123');

JavaScript

import { MostlyGoodMetrics } from '@mostly-good-metrics/javascript';

// Initialize once at app startup
MostlyGoodMetrics.configure({ apiKey: 'mgm_proj_your_api_key' });

// Track events
MostlyGoodMetrics.track('button_clicked');
MostlyGoodMetrics.track('purchase_completed', {
  product_id: 'SKU123',
  price: 29.99,
});

// Identify users
MostlyGoodMetrics.identify('user_123');

Flutter

import 'package:mostly_good_metrics_flutter/mostly_good_metrics_flutter.dart';

// Initialize once at app startup
await MostlyGoodMetrics.configure(
  MGMConfiguration(apiKey: 'mgm_proj_your_api_key'),
);

// Track events
MostlyGoodMetrics.track('button_clicked');
MostlyGoodMetrics.track('purchase_completed', properties: {
  'product_id': 'SKU123',
  'price': 29.99,
});

// Identify users
await MostlyGoodMetrics.identify('user_123');

Capacitor
