I believe this is equivalent to Timer.run, if so, we should use that.

Also- const Duration(milliseconds: 0) is equivalent to const Duration().

Yes. It is. Generally we avoid the empty "const Duration" (although we can't
forbid it). However const Duration(seconds: 0) is shorter and does the same.

Also remove the empty closure: Timer.run(onLoad);
