LogPrinter class abstract

A base class for implementing custom log output formatting.

Subclasses of LogPrinter are responsible for formatting a LogRecord into one or more strings for display, file logging, or other destinations.

Log printers provide flexibility in how logs are presented, making them essential for different environments such as terminals, files, remote logging services, or testing frameworks.

Example:

class SimpleLogPrinter extends LogPrinter {
  @override
  List<String> log(LogRecord record) {
    return ['${record.time.toIso8601String()} [${record.level}] ${record.message}'];
  }
}
