lerp method

@override FTypeface lerp(covariant FTypeface? other, double t)

Linearly interpolates between this FTypeface and other using the given factor t.

Implementation

@override
FTypeface lerp(covariant FTypeface? other, double t) {
  if (other == null) {
    return this;
  }

  return FTypeface(
    fontFamily: t < 0.5 ? fontFamily : other.fontFamily,
    fontFamilyFallback: t < 0.5 ? fontFamilyFallback : other.fontFamilyFallback,
    xs3: .lerp(xs3, other.xs3, t)!,
    xs2: .lerp(xs2, other.xs2, t)!,
    xs: .lerp(xs, other.xs, t)!,
    sm: .lerp(sm, other.sm, t)!,
    md: .lerp(md, other.md, t)!,
    lg: .lerp(lg, other.lg, t)!,
    xl: .lerp(xl, other.xl, t)!,
    xl2: .lerp(xl2, other.xl2, t)!,
    xl3: .lerp(xl3, other.xl3, t)!,
    xl4: .lerp(xl4, other.xl4, t)!,
