# Understand logging | flutter

Ok, So let's start with simple logging first, Which every developer knew

`print()`

easy to start by logging in to flutter. Right 😀

### Okay now, let's play with more sample log data.

1. "Hello world!"
    
2. "I\\'m Kishansinh Parmar"

The result of the logs

As you can see that first 2 sample data print everything correctly but what happen with 3rd sample data? It discards some lines from the output, which we aren't expecting right?

> If you output too much at once, then Android sometimes discards some log lines. To avoid this, use [`debugPrint()`](https://api.flutter.dev/flutter/foundation/debugPrint.html), from Flutter’s `foundation` library. This is a wrapper around `print` that throttles the output to a level that avoids being dropped by Android’s kernel.

> The other option for application logging is to use the `dart:developer` [`log()`](https://api.flutter.dev/flutter/dart-developer/log.html) function. This allows you to include a bit more granularity and information in the logging output.

Now let's print longer string outputs using the log() function. It works ✌🏻

So as we experienced the developer log() function makes sense for logging in to flutter. Nice

### But, wait are you looking for something which is more beautiful for logging then try this package which helps you to log better visible logs.

%[https://pub.dev/packages/logger] 

### Caution ⚠️: This package also reduces your log lines if a message is longer.

So my suggestion is to extend the logger class into your own class and gives your class more power with the developer:log function.

### Tip: Extend Logger class to your own class
