Detect during runtime whether the application is in release mode or not

Question

I got a bunch of tests and debug stuff in my Dart application and I would like to make sure these kind of things are disabled when I build a release version with pub.

Is there any constant or some other way to check if the current running version of the application is a release build or not?

Example:

if (!IS_BUILD) {
   performAutomatedDummyLogin()
} else {
   login();
}

Code in assert(...); is only executed in checked (development) mode. When you run in release mode or build in release mode this code isn't executed.

bool isRelease = true;
assert(() {
  isRelease = false;
  return true;
});

if(isRelease) {
 ...
}
