Android开发NavController清空返回栈

直接上代码：

int sum = ((App)mContext.getApplicationContext()).getNavHostFragment().getNavController().getBackStack().size();
                    for (int i = 0;i<sum;++i){
                        ((App)mContext.getApplicationContext()).getNavHostFragment().getNavController().popBackStack();
                    }
