from static method

GTween from(
  1. Object target,
  2. double duration,
  3. Map vars, [
  4. GVars? nanoVars,
])

Shortcut to start a tween on an target, start from the end values to the start values, this option basically flips the tweens.

Creates a GTween animation that animates the target object from its current properties to the properties defined in vars over the given duration. If provided, nanoVars can be used to configure additional properties of the animation, such as running the animation backwards and rendering the target immediately. If nanoVars is not provided, a new instance of GVars will be used.

Returns a new instance of the created GTween animation.

Implementation

static GTween from(
  Object target,
  double duration,
  Map vars, [
  GVars? nanoVars,
]) {
  nanoVars ??= GVars();
  nanoVars.runBackwards = true;
  nanoVars.immediateRender ??= true;
  return GTween(target, duration, vars, nanoVars);
}
