no logs in ios release mode with filter

cdg720 commented 3 years ago

I am trying to print logs in release mode but I cannot get them printed using LogFilter.

void main() async {
  print("hello");
  logger.d("hello");
  print("hi");
}

final Logger logger = Logger(
  filter: MyFilter(),
);

class MyFilter extends LogFilter {
  @override
  bool shouldLog(LogEvent event) {
    return true;
  }
}

I get no output when I run flutter run --release. How do I get them logged?

iphone x and version 14.7.1

never mind

to see logs in ios release mode, open "devices and simulators" in xcode "windows" tab. in "devices and simulators", click "open console" and you see logs show up there
