Installation

Install the Instalog Flutter SDK by adding it as a dependency in your project. You can find the package on pub.dev. To include the SDK, add the following dependency to your pubspec.yaml file: 
dependencies:
  instalog_flutter: ^0.1.1

​
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_flutter/instalog_flutter.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: 
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.

​
Testing Crash Reporting

Simulate a crash to test your implementation: 
// This will trigger a crash for testing purposes
Instalog.instance.crash.simulateCrash();

​
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_flutter/instalog_flutter.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'),
            ),
          ],
        ),
      ),
    );
  }
}

Troubleshooting

​
Common Issues

  1. SDK Not Initialized
    • Ensure initialize() is called before using other SDK methods
    • Verify your API key is correct
  2. Missing Crash Reports
    • Check that crash reporting is enabled in your configuration
    • Verify your app has network permissions
  3. Events Not Being Logged
    • Check network connectivity
    • Ensure the SDK is properly initialized
