structured_logger 0.0.2

Another logging package, but for structured logging, with the concept of sinks for log output

Structured Logs

structured_logger

Description

The structured_logger package provides an easy way to implement structured logs in your Flutter applications. It allows sending logs to different destinations, such as the terminal or external services, through interfaces called Sinks. The package includes a sample Sink, SimpleLineSink, which sends logs to the terminal.

Installation

Add the following to your pubspec.yaml file:

  structured_logger: ^current_version

Basic Usage

Import the package into your Dart file:

import 'package:structured_logger/structured_logger.dart';

Create an instance of the logger:

final logger = StructureLogger();

Add a Sink to specify where the logs should be sent. For example, to send logs to the terminal, use SimpleLineSink:

LogSink sink = SimpleLineSink();
logger.addSink(sink);

Add other Sinks, if necessary, to send logs to different destinations.

LogSink defaultlog = DefaultSink();
logger.addSink(defaultlog);

Register logs using the log method:

await logger.log(
  "Welcome {name}, your level is {level}",
  level: LogLevel.info,
  data: {"name": "John Doe", "level": 12},
);

terminal output [Fist line is written by SimpleLineSink, and second line is written by DefaultSink.]:

Seja bem vindo John Doe, seu nível é 12
[log] {@t: 2023-12-19T15:38:06.563023, @mt: Seja bem vindo {name}, seu nível é {level}, @l: info, data: {name: John Doe, level: 12}}

Fist line is written by SimpleLineSink, and second line is written by DefaultSink.

This is a simple example, and you can customize Sinks and log data as needed. For example, you can create a Sink that sends logs to an external service, such as Seq or Elastic. (Or use another package that already does this, such as (WIP)).
