## What it is
A small, extensible Dart/Flutter logging library that prints beautifully formatted, colorful log messages with configurable levels, printers, filters, and outputs. It supports console, file, memory, and stream outputs plus pluggable printer decorators.

## Use cases
- print pretty colored logs in a Flutter app
- log debug and error messages in Dart with different severity levels
- write logs to a file with buffering and rotation
- filter log levels in production vs development
- customize log output format with emojis, timestamps, and stack traces

## When to avoid
- you need centralized log aggregation or structured logging pipelines
- your project is not Dart/Flutter based
- you rely on the original leisim repo, which is no longer maintained (moved to SourceHorizon/logger)

## Facets
- artifact type: library
- maturity: active
- function: logging
- domain: developer-tools, backend, mobile-development
- platform: cross-platform
- tags: dart, flutter, pretty-printing, log-levels, console-output, file-output
