lerp static method

RowTooltipTheme lerp(
  1. RowTooltipTheme? a,
  2. RowTooltipTheme? b,
  3. double t
)

Linearly interpolate between two RowTooltipThemes.

Non-interpolable fields snap at t = 0.5, as the other themes do.

Implementation

static RowTooltipTheme lerp(
  RowTooltipTheme? a,
  RowTooltipTheme? b,
  double t,
) {
  if (a == null && b == null) return const RowTooltipTheme();
  if (a == null) return b!;
  if (b == null) return a;

  return RowTooltipTheme(
    direction: t < 0.5 ? a.direction : b.direction,
    alignment: t < 0.5 ? a.alignment : b.alignment,
    offset: lerpDouble(a.offset, b.offset, t) ?? 8.0,
    crossAxisOffset:
        lerpDouble(a.crossAxisOffset, b.crossAxisOffset, t) ?? 0.0,
