Console.log in Dart Language

How can I log into the browser console, like console.log in JavaScript, from the Dart language?

Solution 1:

Simple:

print('This will be logged to the console in the browser.');

A basic top-level print function is always available in all implementations of Dart (browser, VM, etc.). Because Dart has string interpolation, it's easy to use that to print useful stuff too:

var a = 123;
var b = Point(2, 3);
print('a is $a, b is ${b.x}, ${b.y}');

Solution 2:

Also, dart:html allows use of window.console object.

import 'dart:html';

void main() {
  window.console.debug("debug message");
  window.console.info("info message");
  window.console.error("error message");
}
