HttpLogStrategy class abstract

Base class for HTTP-based logging strategies.

Provides shared functionality for strategies that send logs to remote HTTP endpoints, including:

• Batch processing with configurable size and timeout
• Retry logic with exponential backoff
• HttpClient management
• Proper resource disposal

Subclasses only need to implement formatLogEntry, endpoint, headers, and strategyName to create a fully functional HTTP logging strategy.

Example:

class MyHttpStrategy extends HttpLogStrategy {
  MyHttpStrategy({required this.apiKey})
      : super(batchSize: 100, batchTimeout: Duration(seconds: 5));

  final String apiKey;

  @override
  String get strategyName => 'MyHttpStrategy';
  @override
  String get endpoint => 'https://api.example.com/logs';
  @override
  Map<String, String> get headers => {'Authorization': 'Bearer $apiKey'};
  @override
  Map<String, dynamic> formatLogEntry(LogEntry entry) => entry.toMap();
}
