Execute print command only at Debug

[vincius0000]

Hello!

Currently IDE gives lot of warning of Print being used in Production. I suggest adding following file to utils folder and replacing print with Logger.printDebug everywhere

// logger.dart
import 'package:flutter/foundation.dart';

class Logger {
  static void printDebug(String message) {
    if (kDebugMode) {
      print(message);
    }
  }
}

Unless there's a specific purpose the print is being used in Prod build.

Good idea! I will need to see how other apps manage this in terms of code. PRs appreciated
