Support multiple printers

[chimon2000]

It would be nice to be able to log using multiple printers, for instance if I want to use the flutter printer to log to dart devtools, but also use the pretty printer to log in the terminal.

Hey @chimon2000. You can extend LoggyPrinter to make your own printer for logging in any way you would want/need to. Here is simple example of custom multiple printer:

class MultiPrinter extends LoggyPrinter{
  MultiPrinter({
    required this.consolePrinter,
    required this.cloudPrinter,
    required this.filePrinter,
});

  final LoggyPrinter consolePrinter;
  final LoggyPrinter cloudPrinter;
  final LoggyPrinter filePrinter;

  @override
  void onLog(LogRecord record){
    consolePrinter.onLog(record);
    filePrinter.onLog(record);
    
    // Log to cloud only if app is run in release mode
    if(kReleaseMode) {
      cloudPrinter.onLog(record);
    }
  }
}
