Developed with 💙 by Instalog 🚀

A Flutter plugin for integrating Instalog analytics, logging, and crash reporting services into your Flutter applications. Instalog provides a comprehensive solution for monitoring app performance, user behavior, and error tracking.

Features

• Event Logging: Track custom events with flexible parameters
• User Identification: Associate events with specific users
• Crash Reporting: Automatically capture and report crashes
• Feedback Collection: In-app feedback modal for user input

Installation

Add instalog_flutter: ^0.1.3 to your pubspec.yaml:

dependencies:
  instalog_flutter: ^0.1.3

Platform-specific Setup

Android

For feedback functionality on Android, ensure you have the Instalog activity registered in your AndroidManifest.xml:

<activity
  android:name="dev.instalog.mobile.feedback.InstalogFeedbackActivity"
  android:label="Instalog"
  android:theme="@style/Theme.Instalog"/>

Usage

Initialization

Initialize the Instalog SDK at the start of your app:

import 'package:instalog_flutterinstalog.dart';

// Initialize in main.dart
void main() {
  // Set up crash handling
  Instalog.instance.crash.setup(
    appRunner: () => runApp(const MyApp()),
  );
}

// Initialize with your API key in a widget
@override
void initState() {
  super.initState();
  Instalog.instance.initialize(apiKey: 'your_api_key_here');
}

### Configuration Options

Customize Instalog SDK behavior with `InstalogOptions`:

```dart
import 'package:instalog_platform_interface/instalog_platform_interface.dart';

// Initialize with custom options
Instalog.instance.initialize(
  apiKey: 'your_api_key_here',
  options: const InstalogOptions(
    isLogEnabled: true,     // Enable event logging
    isLoggerEnabled: false, // Disable internal debug logs
    isCrashEnabled: true,   // Enable crash reporting
    isFeedbackEnabled: true // Enable feedback modal
  ),
);

All configuration options default to true except for isLoggerEnabled (defaults to false).

Logging Events

Track custom events with optional parameters:

// Simple event
Instalog.instance.logEvent(event: 'button_clicked');

// Event with parameters
Instalog.instance.logEvent(
  event: 'user_login',
  params: {
    'user_id': '12345',
    'method': 'email',
    'timestamp': DateTime.now().toIso8601String(),
  },
);

Showing Feedback Modal

Display the in-app feedback modal to collect user input:

await Instalog.instance.showFeedbackModal();

Crash Reporting

Instalog automatically captures uncaught exceptions when set up with crash.setup(). To manually report a caught exception:

try {
  // Your code that might throw an exception
} catch (error, stack) {
  Instalog.instance.sendCrash(error, stack);
}

User Identification

Associate events with a specific user:

// Identify user with a unique ID
Instalog.instance.identifyUser(userId: 'user_12345');

Identifying users allows you to track user-specific behavior and associate events and crashes with particular users, which is helpful for debugging and analytics.

Platform-Specific Notes

iOS

Ensure you have added the necessary permissions to your Info.plist file if your app collects user data.

Android

If targeting Android 13 (API level 33) or higher, ensure you request the appropriate permissions for collecting user data.

Advanced Example

Here's a complete example showing how to use multiple Instalog features together:

import 'package:flutter/material.dart';
import 'package:instalog_flutterinstalog.dart';
import 'package:instalog_platform_interface/instalog_platform_interface.dart';

void main() {
  // Set up crash handling
  Instalog.instance.crash.setup(
    appRunner: () => runApp(const MyApp()),
  );
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: HomePage(),
    );
  }
}

class HomePage extends StatefulWidget {
  @override
  _HomePageState createState() => _HomePageState();
}

class _HomePageState extends State<HomePage> {
  @override
  void initState() {
    super.initState();
    // Initialize with options
    Instalog.instance.initialize(
      apiKey: 'your_api_key_here',
      options: const InstalogOptions(
        isLogEnabled: true,
        isLoggerEnabled: false,
        isCrashEnabled: true,
        isFeedbackEnabled: true,
      ),
    );
    
    // Identify the user
    Instalog.instance.identifyUser(userId: 'user_${DateTime.now().millisecondsSinceEpoch}');
    
    // Log app start event
    Instalog.instance.logEvent(
      event: 'app_started',
      params: {
        'timestamp': DateTime.now().toIso8601String(),
        'version': '1.0.0',
      },
    );
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: const Text('Instalog Example')),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: [
            ElevatedButton(
              onPressed: () => Instalog.instance.showFeedbackModal(),
              child: const Text('Show Feedback Modal'),
            ),
            ElevatedButton(
              onPressed: () {
                try {
                  // Simulate an error
                  throw Exception('Test exception');
                } catch (error, stack) {
                  Instalog.instance.sendCrash(error, stack);
                }
              },
              child: const Text('Simulate & Report Error'),
            ),
          ],
        ),
      ),
    );
  }
}
