Log Printers

This module uses the Strategy pattern for log output. Each printer defines how logs are formatted and sent to the final destination (console, terminal, etc.).

LogPrinterBase

Abstract contract for all log printers.

abstract class const LogPrinterBase() {

  void printLog(LoggerObjectBase log);
}

To create a custom printer, extend LogPrinterBase and implement printLog.

LogSimplePrint

Simple printer without color formatting. Uses print().

Typical output:

[ClassName] dd/MM/yyyy HH:mm:ss.SSS Log message

Recommended for:

Environments without ANSI support (basic terminals, CI/CD, external log pipelines)
Automated tests requiring clean output
Production file-oriented logging

Shortcut:

registerLogPrinterSimple(config: ConfigLog(enableLog: true));

LogWithColorPrint

ANSI color printer using dart:developer.log().

Recommended for:

Local development
Visual debugging with log color differentiation
Environments with ANSI and dart:developer support

Shortcut:

registerLogPrinterColor(
  config: ConfigLog(enableLog: true),
  maxLogsInCache: 200,
);

Comparison

Printer	Output	ANSI	Recommended use
`LogSimplePrint`	`print()`	❌	Tests, CI/CD, production
`LogWithColorPrint`	`dart:developer.log()`	✅	Local development
