Hi Johannes! Great video!
I wanted to share that, in case somebody is looking for a simpler solution for something that doesn't need too much control over what's logged, it is possible to get the information of the class invoking the logger without the need of passing it as a parameter using for example:
logger.d('$runtimeType: <YOUR MESSAGE>');

if your class is MyClass, the output will be:
MyClass: YOUR MESSAGE


But when more control over the logs is needed, the solution you proposed is really really good!

Hi,

Thank you for the video.
Really good job on explaining this concept :)

Great and very usefull video. In the current flutter version I am getting a waring for the closure:
final logger = (Type type) => Logger( printer:
With the recommendation to Use a function declaration rather than a variable assignment to bind a function to a name.
Try rewriting the closure assignment as a function


What is the best way to make it clean? Thanks

How can I print the time in the CustomPrinter class?

Hello Johannes,

can I also save the data locally so that I can view it after a crash of the app? Or better, can I send the locally stored log messages to me in the event of a crash after user consent?

Thanks for the great video, Michael

To avoid waring. Use below code.

logger(Type className){
return Logger(
printer: CustomLogger(className.toString()),
level: Level.debug,
filter: null, // Use the default LogFilter (-> only log in debug mode)
output: null, // Use the default LogOutput (-> send everything to console)
);
}

Hi Johannes,

How can I fulfill the hint of the rule? I get the hint: "Use a function declaration to bind a function to a name."

final logger = (Type type) => Logger(
printer: CustomerPrinter(type.toString()),
level: Level.verbose,
);

Hi, Johannes.
Nice tut.
Can we do remote logging using the same concept?
