Actual Icon height is greater than `size`

[Noah765]

[Describe the bug
FaIcon widgets are bigger than expected. This widget: FaIcon(FontAwesomeIcons.one, size: 200), for example, renders at about 100x209 pixels.

To reproduce
In the following example you can clearly see that the height of the container is greater than 200 pixels. Using the Flutter devtools, you can see that the size of the FaIcon widget is 100x209 pixels.

Container(
  decoration: BoxDecoration(border: Border.all()),
  child: Row(
    mainAxisSize: MainAxisSize.min,
    children: [
      const FaIcon(FontAwesomeIcons.one, size: 200),
      Container(width: 10, height: 200, color: Colors.red),
    ],
  ),
),

Expected behavior
I would expect the height of the icon in the example to be 200 pixels

Screenshots

Desktop
Taken from flutter doctor:

Flutter (Channel stable, 3.24.4, on NixOS 25.05 (Warbler) 6.6.64, locale en_US.UTF-8)

I do not currently have the necessary tools installed to run this example in debug mode on any platform other than Linux, although I can confirm that this problem is also present when building for the web, with the same observation as on my NixOS desktop with the example above.

I am facing the same issue and agree that #144 would fix this issue

A temporary solution is wrap the FaIcon() in a SizedBox() with height and width set to the icon size:

SizedBox(
  height: widget.iconSize ,
  width: widget.iconSize,
  child: FaIcon(
    FontAwesomeIcons.crosshairs,
    size: widget.iconSize,
  ),
),

Other temporary solutions include replacing FaIcon with Icon, which does the same thing as wrapping FaIcon in a SizedBox as you have done. With this approach you lose the flexibility of dynamic aspect ratios for different icons, which is the whole point of FaIcon, but you gain the benefit of predictability when it comes to icon sizes.
Another option is to construct the icons yourself by copying https://github.com/fluttercommunity/font_awesome_flutter/blob/master/lib/src/fa_icon.dart#L142..L158 and adding height: 1, to the TextStyle.
