| 2 | + |
| 3 | +> Flutter SDK for Aptabase, an open-source, privacy-first analytics platform for Mobile, Desktop, and Web apps. GDPR-compliant, no cookies, no tracking of personal data. |
| 4 | + |
| 5 | +Package: `aptabase_flutter` |
| 6 | +Install: `flutter pub add aptabase_flutter` |
| 7 | +Registry: https://pub.dev/packages/aptabase_flutter |
| 8 | +Repo: https://github.com/aptabase/aptabase_flutter |
| 9 | + |
| 10 | +## Overview |
| 11 | + |
| 12 | +Aptabase is an open-source, privacy-first analytics platform. This SDK integrates Aptabase into Flutter apps. |
| 13 | + |
| 14 | +- Get your App Key from the Aptabase dashboard (Settings > Instructions) |
| 15 | +- App keys follow the format `A-EU-*` (European), `A-US-*` (US), or `A-SH-*` (self-hosted) |
| 16 | +- Only strings and numbers are allowed as custom property values |
| 17 | +- All tracking is non-blocking and runs in the background |
| 18 | +- No events are tracked automatically — you must call `trackEvent` manually |
| 19 | + |
| 20 | +## Installation |
| 21 | + |
| 22 | +```shell |
| 23 | +flutter pub add aptabase_flutter |
| 24 | +``` |
| 25 | + |
| 26 | +### Android Requirement |
| 27 | + |
| 28 | +Add internet permission to `AndroidManifest.xml`: |
| 29 | + |
| 30 | +```xml |
| 31 | +<uses-permission android:name="android.permission.INTERNET" /> |
| 32 | +``` |
| 33 | + |
| 34 | +## Initialization |
| 35 | + |
| 36 | +Initialize the SDK in your `main.dart` before `runApp`: |
| 37 | + |
| 38 | +```dart |
| 39 | +import 'package:aptabase_flutter/aptabase_flutter.dart'; |
| 40 | + |
| 41 | +void main() async { |
| 42 | + WidgetsFlutterBinding.ensureInitialized(); |
| 43 | + await Aptabase.init('<YOUR_APP_KEY>'); |
| 44 | + |
| 45 | + runApp(const MyApp()); |
| 46 | +} |
| 47 | +``` |
| 48 | + |
| 49 | +**Important:** Your `main` function must be `async` and you must call `WidgetsFlutterBinding.ensureInitialized()` before `Aptabase.init`. |
| 50 | + |
| 51 | +## Track Events |
| 52 | + |
| 53 | +```dart |
| 54 | +import 'package:aptabase_flutter/aptabase_flutter.dart'; |
| 55 | + |
| 56 | +// Track a simple event |
| 57 | +Aptabase.instance.trackEvent('app_started'); |
| 58 | + |
| 59 | +// No need to await — runs in the background |
| 60 | +Aptabase.instance.trackEvent('button_clicked'); |
| 61 | +``` |
| 62 | + |
| 63 | +## Track Events with Properties |
| 64 | + |
| 65 | +```dart |
| 66 | +Aptabase.instance.trackEvent('purchase_completed', { |
| 67 | + 'product': 'Premium Plan', |
| 68 | + 'price': 9.99, |
| 69 | + 'currency': 'USD', |
| 70 | +}); |
| 71 | + |
| 72 | +Aptabase.instance.trackEvent('level_completed', { |
| 73 | + 'level': 5, |
| 74 | + 'score': 1200, |
| 75 | +}); |
| 76 | +``` |
| 77 | + |
| 78 | +Property values must be strings or numbers (int, double). No booleans, lists, or maps. |
| 79 | + |
| 80 | +## Configuration |
| 81 | + |
| 82 | +Pass `InitOptions` as the second argument to `Aptabase.init`: |
| 83 | + |
| 84 | +```dart |
| 85 | +await Aptabase.init( |
| 86 | + '<YOUR_APP_KEY>', |
| 87 | + const InitOptions( |
| 88 | + host: 'https://your-self-hosted-instance.com', // only for self-hosted (A-SH-* keys) |
| 89 | + tickDuration: Duration(seconds: 30), // flush interval (default: 30s) |
| 90 | + batchLength: 25, // max events per batch (default/max: 25) |
| 91 | + printDebugMessages: false, // enable SDK debug logging |
| 92 | + ), |
| 93 | +); |
| 94 | +``` |
| 95 | + |
| 96 | +- `host` — Required only for self-hosted instances (`A-SH-*` app keys) |
| 97 | +- `tickDuration` — How often queued events are flushed to the server (default: 30 seconds) |
| 98 | +- `batchLength` — Max events sent per flush (default and max: 25) |
| 99 | +- `printDebugMessages` — Enable SDK debug logging via `developer.log` |
| 100 | + |
| 101 | +## Platform Notes |
| 102 | + |
| 103 | +- Supported platforms: Android, iOS, macOS, Web, Linux, Windows |
| 104 | +- Sessions auto-rotate after 1 hour of inactivity |
| 105 | +- Events are queued locally and sent in batches for reliability |
| 106 | +- The SDK automatically collects OS name, OS version, locale, app version, and build number |
| 107 | +- Debug mode is auto-detected via `kDebugMode` |
| 108 | +- When submitting to the Apple App Store, see the [App Privacy guide](https://aptabase.com/docs/apple-app-privacy) |
