class - How to actively delete a Dart object? -


i'm building dart app contains variety of class objects. particular class object i'm dealing contains variety of stream event listeners on dom elements. when remove these objects dom , untrack class object these listeners persist.

i know dart runs garbage collection eventually, i'm not 100% sure come along , delete these class objects since there watcher , stream listeners continue.

my question is, there way actively delete class object immediately? tried setting class object null doesn't seem work reason. when check if object exists afterward print statement, still lists instance of class object.

furthermore, i'm trying accomplish, canceling streams doesn't seem enough. need destroy class object.

setting references null can do. test seems weird. how can print object if don't have reference? if still have reference, how can expect instance collected.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
