speed method

AnimationSpec speed(
  1. double speed
)

Returns a copy of this AnimationSpec with the given speed.

For example a speed of 0.5 will cause the animation to run at half speed.

Examples

import 'package:flutter/animation.dart';

final withSpeed = Curves.linear.animation().speed(0.5);

Implementation

AnimationSpec speed(double speed) {
  if (speed <= 0) {
    throw ArgumentError.value(speed, 'speed', 'must be greater than zero.');
  }
  return _copyWith(speed: speed);
}
