debugging - Does Dart have a 'breakpoint' statement?

Question

Is there a statement in Dart to make the debugger halt without setting a breakpoint while debugging?

There are situations where it would be helpful be able to hardcode a breakpoint. I run into this for example to simplify remote debugging, to ensure the execution stops early and then I can add further breakpoints using the debugger.

Answer 1

This was just introduced (Dart VM version: 1.11.0-edge.131775 (Tue Jun 2 14:25:22 2015) on "linux_x64")

import 'dart:developer'; 

void main() {
  debugger(); 
  // or
  debugger(msg: 'because I say so');
}

there is also a conditional variant

// Debugger.breakHereIf(bool expr); // current
debugger(when: somethingIsTrue, msg: 'investigate'); // later
