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.
Examples
In the following example, we print numbers from 1 to 20, to console, without a trailing newline.
main.dart
import 'dart:io'; void main() { var i = 1; while (i <= 20) { stdout.write(i); i++; } }
Output
1234567891011121314151617181920
We may append a space or newline manually, if required.
In the following example, we print a space after each number.
main.dart
import 'dart:io'; void main() { var i = 1; while (i <= 20) { stdout.write(i); stdout.write(' '); i++; } }
Output
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20
