The C callback function registered through ffi invalidates both asynchronous operations and timers during the callback

[lujun495904500]

// asynchronous operation test
void asyncTest() async {
  await Future.value(12);
  print('async test');
}

// timer test
void timerTest() async {
  print('timer test');
}

...
// c callback function registered through ffi
glfwSetKeyCallback(window, (window, key, scancode, action, mods) {
    if (GLFW_RELEASE == action) {
      if (GLFW_KEY_SPACE == key) {
        print('key code : $key');
        test();
        Timer(Duration(milliseconds: 10), testKeyCallback);
      }
    }
  });

Press space and output:

key code : 32

quit program and output:

key code : 32
async test
timer test

Hi @lujun495904500!

I'm not entirely sure I understand your problem. Could you elaborate on the expected behavior and the actual behavior.

Also, could you provide a reproduction in a repo? Then I can look at all the code, the code above is incomplete.

Thanks for your answer, and finally checked, it is really my logic question @dcharkes
