Can you try using callback instead of value in the delegate.
example:

ValueDelegate.gradientColor(
  const ['灯光', '灯光', 'Gradient Fill 2'],
  callback: (_) => [colorList[i], Colors.white],
),

Let me know if it helps.

I try to replace this code:

ValueDelegate.gradientColor(
  const ['灯光', '灯光', 'Gradient Fill 2'],
  callback: (_) => [colorList[i], Colors.white],
),

but it can not helps.

It seems there is a bug in the update of the gradient.
In the mean time to unblock you, you can set a key in the Lottie widget like this:

  @override
  Widget build(BuildContext context) {
    return Lottie.asset(
      'assets/blub.json',
      key: ValueKey(i),
      delegates: LottieDelegates(
        text: (initialText) => '**$initialText**',
        values: [
          ValueDelegate.color(
            const ['灯泡', '灯泡', '填充 1'],
            value: colorList[i],
          ),
          ValueDelegate.gradientColor(
            const ['灯台', '灯台', 'Gradient Fill 1'],
            value: [Colors.black, Colors.grey],
          ),
          ValueDelegate.gradientColor(
            const ['灯光', '灯光', 'Gradient Fill 2'],
            value: [colorList[i], Colors.white],
          ),
        ],
      ),
    );
  }
