getLinearGradient method

Implementation

LinearGradient? getLinearGradient(double value) {
  if (startColors == null || endColors == null) return null;
  return LinearGradient(
    colors: lerpColors(startColors, endColors, value) ?? [],
    stops: lerpStops(startStops, endStops, value),
    begin: startAlignment ?? Alignment.topLeft,
    end: endAlignment ?? Alignment.bottomRight,
  );
}
