Question

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

Answer 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}');
