Reducing the number of considered missed Gc histogram windows from 101 to 100

I am attempting to build a weather app as part of a Flutter course I am taking, and a message stating:

Reducing the number of considered missed Gc histogram windows from 101 to 100

appears in my console, when I would expect weather data instead. Is anyone familiar with this message?

I am pasting the code from the screens involved below, for reference.

  void initState() {
    super.initState();
    print(widget.locationWeather);
  }
