fimber #

Extensible logging for Flutter.

Based on famous Android logging library - Timber, this is library for simplify logging for Flutter. Using similar (as far as Dart lang allows) method API with same concepts for tree and planting logging tree.

Getting Started #

To start add using it:

  • Add fimber to pubspec.yaml
  fimber: ^0.1.0
  • Start using it with static methods:
import 'fimber.dart';

void main() {
  var parameter = 343.0;
  // use directly
  Fimber.i("Test message $argument");
  Fimber.i("Extra error message", ex: Exception("Test thorwable"));
  // other log levels

This will log the value and grab a TAG from stacktrace - that is little costly and if more logs will be done per second.

  • Create tagged version of Fimber and use its instance inside class, you can create logger for a dart file or for a class.
var logger = FimberLog("MY_TAG");

void main() {
  logger.d("Test message");

// or inside a class
class SomeBloc {
  var logger = FimberLog("SomeBloc");
  String fetchMessage() {
    logger.d("About to fetch some data.");
    var data = "load something";

    logger.d("Retrived data (len = ${data.length}");
    return data;

TODO - road map #

  • un-plant single tree
  • Make this Dart only Logger and use flutter dependency only for plugins
  • Add Tree for platform specific log/tag logging via channels - plugins
  • Add Crashlytics plugin (maybe other remote logger tools) with flutter_crashlytics

[0.1] - First Version

Initial version with Fimber debugging and DebugTree


import 'package:fimber/fimber.dart';

void main() {
  // plant a tree - DebugTree()

  Fimber.d("Test message", ex: Exception("test error"));
  var parameter = 100.0;
  Fimber.w("Test message with parameter: $parameter");

  var logger = FimberLog("MY_TAG");
  logger.d("Test message", ex: Exception("test error"));
  logger.w("Test message with parameter: $parameter");
