Package Overview

Package selection guidance compiled from public package information, community data, and project usage.

Roggle is a simple, colorful, and easily extensible logging package for Dart, inspired by the popular logger library. It provides a clean and intuitive API for outputting logs across multiple platforms, including Android, iOS, Web, macOS, Windows, and Linux. With vibrant color coding and customizable formatting, Roggle enhances debug visibility without adding complexity. Its lightweight design makes it ideal for both development and production use, especially when developers want a visually distinct logging experience with minimal setup. The package integrates seamlessly into Flutter projects via pub.dev.

Use cases

  • Debugging application flow
  • Monitoring runtime behavior
  • Enhancing log readability in development
  • Cross-platform logging
  • Quick integration into existing projects
  • Visual differentiation of log levels

Key features

  • Colorful console output
  • Simple and intuitive API
  • Extensible design
  • Multi-platform support
  • Minimal configuration
  • Log level filtering

Suitable for

  • Developers seeking visual log clarity
  • Flutter apps needing lightweight logging
  • Teams prioritizing developer experience
  • Projects requiring easy-to-read debug output
  • Fast prototyping with clear feedback
  • Simple logging without heavy dependencies

Considerations

  • Not suitable for high-volume production logging
  • Limited advanced features compared to full-featured loggers
  • Color output may not be useful in non-terminal environments
  • Depends on external logger for core functionality
  • May require additional configuration for custom formatters
  • Best used in development or low-throughput scenarios

Roggle

Test codecov MIT

Simple, colorful and easy to expand logger for dart.
Inspired by the logger and dependent to the logger.

Getting Started

Just create an instance of Roggle and start logging:

import 'package:roggle/roggle.dart';

final logger = Roggle();

logger.d('Roggle is working!');

Instead of a string message, you can also pass other objects like List, Map, Set or Function.

Output

Android Studio

Documentation

Roggle's API is almost the same as the logger. See the logger for basic usage.

Difference from the logger

  • Printer defaults to SinglePrettyPrinter class.
  • Not try-catch at LogOutput class, because we want to stop the process.
  • Added some getters in Roggle class.
  • Changed the log interface dynamic to Object?.

Options

If you use the SinglePrettyPrinter, there are more options:

final logger = Roggle(
  printer: SinglePrettyPrinter(
    loggerName: '[APP]', // Print a logger name for each log message
    colors: true, // Colorful log messages
    printCaller: true, // Print a caller for each log message
    printLocation: true, // Print a location of caller for each log message
    printFunctionName: true, // Print a function name of caller for each log message
    printEmojis: true, // Print an emoji for each log message
    printLabels: true, // Print a level string for each log message
    printTime: true, // Print a timestamp for each log message
    stackTraceLevel:
        Level.error, // The current logging level to display stack trace
    stackTraceMethodCount: 10, // Number of stack trace methods to display
    stackTracePrefix: '>>> ', // Replace stack trace prefix
    levelColors: {}, // Replace level colors map
    levelEmojis: {}, // Replace level emojis map
    levelLabels: {}, // Replace level labels map
    timeFormatter: (now) => DateFormat('yyyy/MM/dd HH:mm:ss.SSS')
        .format(now), // Replace time formatter
  ),
);

SinglePrettyPrinter

You can use the Roggle.crashlytics() to send errors and logs using the FirebaseCrashlytics API in release mode.

final logger = Roggle.crashlytics(
  printer: CrashlyticsPrinter(
    errorLevel: Level.error, // Logs above this level will call onError
    onError: (event) {
      // Send an error to Firebase Crashlytics as follows
      FirebaseCrashlytics.instance.recordError(
        event.exception,
        event.stack,
        fatal: true,
      );
    },
    onLog: (event) {
      // Send logs to Firebase Crashlytics as follows
      FirebaseCrashlytics.instance.log(event.message);
    },
    loggerName: '[APP]',
    printCaller: true, // Print a caller for each log message
    printLocation: true, // Print a location of caller for each log message
    printFunctionName: true, // Print a function name of caller for each log message
    printEmojis: true, // Print an emoji for each log message
    printLabels: true, // Print a level string for each log message
    levelEmojis: {}, // Replace level emojis map
    levelLabels: {}, // Replace level labels map
  ),
);

Tips

If you want to stop the process at the same time as the error log, do the following.

import 'package:roggle/roggle.dart';

final logger = Roggle(
  output: AssertionOutput(),
);

class AssertionOutput extends ConsoleOutput {
  @override
  void output(OutputEvent event) {
    super.output(event);
    if (event.level.index >= Level.error.index) {
      throw AssertionError('Stopped by logger.');
    }
  }
}
