flutter pub add one_line_logger

Example

Next, import 'one_line_logger.dart' into your Dart code.

import 'package:one_line_logger/one_line_logger.dart';

// Initialise the logger. User stats are logged automatically!
final logger = OneLineLogger();

// Log custom messages
logger.error('Error message $e');
logger.debug('User purchased item: $item');

Web Requirement

Add your App ID to index.html

Notes

For simplicity, logs are public by default and can be accessed by entering your App ID on the dashboard. Ensure no sensitive data is logged, or subscribe to enable data privacy.
