not work on iOS (Android is fine)

[orliu]

I got some logs like these on iOS:

flutter: ^[[38;5;246mI/17:21:00 flutter: ^[[38;5;246mI/17:21:00 flutter: ^[[38;5;246mI/17:21:00 flutter: ^[[38;5;246mI/17:21:00 flutter: ^[[38;5;246mI/17:21:00 flutter: ^[[38;5;246mI/17:21:00

How can I solve this problem?

@orliu One year later, did you manage to solve this?

I have solved this issue

    const String RED = '\u001b[31m';
    const String GREEN = '\u001b[32m';
    const String YELLOW = '\u001b[33m';
    const String BLUE = '\u001b[34m';
    const String RESET = '\u001b[0m';
    
    if (Platform.isIOS) {
            String color;
            switch (log.logLevel) {
              case LogLevel.ERROR:
                color = RED;
                break;
              case LogLevel.FATAL:
                color = RED;
                break;
              case LogLevel.WARNING:
                color = YELLOW;
                break;
              case LogLevel.INFO:
                color = BLUE;
                break;
              case LogLevel.DEBUG:
              case LogLevel.TRACE:
                color = BLUE;
                break;
              default:
                color = '';
            }
            developer.log("$color${Formatter.format(log, _config)}$RESET");
   } else{
   // log using this package
   }
    

I am using custom logger and this works

'\u001b[31m' is the 3bit color for ansi and the package uses 8bit color. This library was written a very long time ago; but I'm happy to take PRs.

I'll research more about this and create a PR. I wonder what is happening in iOS side which causes the issue.

This issue does not affect the actual development work, it takes too long, so I will close it first
