DO avoid print calls in production code.

For production code, consider using a logging framework. If you are using Flutter, you can use debugPrint or surround print calls with a check for kDebugMode

BAD:

void f(int x) {
  print('debug: $x');
  ...
}

GOOD:

void f(int x) {
  debugPrint('debug: $x');
  ...
}

GOOD:

void f(int x) {
  log('log: $x');
  ...
}

GOOD:

void f(int x) {
  if (kDebugMode) {
      print('debug: $x');
  }
  ...
}
