How to print output on same line in dart Pad ? I am unable to stdout.write('hello');

import 'dart:io';
main()

 stdout.write('hi, ');

// Unable to use the stdout,write() on dart Io Pad ? //Uncaught Error: Unsupported operation: StdIOUtils._getStdioOutputStream

By using the direct print() method (Support to Dartpad)

void main() {
   for(int i = 0; i < 5; i++){
      print('Text ' * i);
   }
}

Output:
Text 
Text Text 
Text Text Text 
Text Text Text Text

Example for when multiplying by 0, 1, 2

void main() {
  print('Text' * 1);
  print('Text' * 0);
  print('Text' * 2);
}

Output:
Text

TextText

You're getting this error because DartPad does not support dart:io.

Also, DartPad does not support libraries from packages. DartPad supports dart:* libraries that work with web apps.

If you want to use dart:io you'll need to install Dart SDK on your computer or on a virtual machine on the cloud.
