[BUG] Line height issue with Figma Tokens

💬 Line height issue with Figma Tokens.

This is a example of a textstyle token generated

TextStyle get m3BodyLarge => const TextStyle(
fontFamily: 'Roboto',
fontSize: 16.0,
fontWeight: FontWeight.w400,
height: 24.0,
letterSpacing: 0.5,
);

Here because of the way the height in flutter for textStyle works is like (height x fontSize). Because of this issue each line's height becomes very big making textStyle tokens unusable, while the similar token works for web because there its height is in pixels but with flutter its different, here is directly multiplies with the fontSize.

Please fix this if possible
Thank You

for now I have made a extension to fix this issue on my side like this.

extension NewStyle on TextStyle {
  TextStyle fixLineHeight(BuildContext context) {
    double pixelFontSize = fontSize!;
    double pixelLineHeight = height!;

    double pixelRatio = MediaQuery.of(context).devicePixelRatio;
    double logicalFontSize = pixelFontSize / pixelRatio;
    double logicalLineHeight = pixelLineHeight / pixelRatio;
    return copyWith(height: logicalLineHeight / logicalFontSize);
  }
}
