// Well ... no. Await is non-blocking. Your example is misleading once again :-)

// Example A:
ranBool(5).then((ret) => print(ret.toString()));
new Timer(const Duration(seconds: 2), () {
  print('timer finished');
});

// is NOT the same as Example B:
if (await ranBool(5))
  print('true');
else
  print('false');
new Timer(const Duration(seconds: 2), () {
  print('timer finished');
});

// Without the await magic, Example B would look like this (Example C):
ranBool(5).then((ret) {
  print(ret.toString()));
  new Timer(const Duration(seconds: 2), () {
    print('timer finished');
  });
});
