unsupported import(s): (dart:io)

You can access the value of an expression inside a string by using ${expression} . var greeting = “Hello”; var person = “Rohan”; print(“${greeting}, ${person}!”); // prints “Hello, Rohan!” If the expression is an identifier, the {} can be skipped.

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).

You can use stdout : import “dart:io”; stdout. write(“foo”); will print foo to the console but not place a \n after it.28 May 2017
