I'm trying to print a message to stderr. Is there a way to pass the stderr filehandle to print?

How do you print darts in one line? Dart – Print without Newline To print a string to console without a trailing new line in Dart, import dart:io library, and call stdout. write() function with the string passed as argument to it.
You can use stdout : import "dart:io"; stdout. write("foo"); will print foo to the console but not place a \n after it.
If you simlpy want to print text to the console you can use print('Text') . But if you want to access the advanced fatures of the DevTools console you need to use the Console class from dart:html : Console. log('Text') . It supports printing on different levels (info, warn, error, debug).
Stdout represents the IOSink for either stdout or stderr . It provides a blocking IOSink , so using this to write will block until the output is written. In some situations this blocking behavior is undesirable as it does not provide the same non-blocking behavior as dart:io in general exposes.
Found it:
stderr.write("Message");
