How to reproduce?

class _MyHomePageState extends State<MyHomePage> {
  String textName = "短文本";

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        backgroundColor: Theme.of(context).colorScheme.inversePrimary,
        title: Text(widget.title),
      ),
      body: Container(
        color: Colors.white,
        padding: const EdgeInsets.symmetric(vertical: 50, horizontal: 10),
        child: Column(
          crossAxisAlignment: CrossAxisAlignment.start,
          children: [
            FilledButton(
              onPressed: () {
                setState(() {
                  if (textName == "短文本") {
                    textName = "转朱阁，低绮户，照无眠。不应有恨，何事长向别时圆？人有悲欢离合，月有阴晴圆缺，此事古难全。但愿人长久，千里共婵娟";
                  } else {
                    textName = "短文本";
                  }
                });
              },
              child: const Text("rebuild"),
            ),
            const SizedBox(height: 50),
            ExtendedText(
              textName,
              // key: ValueKey(textName),
              maxLines: 1,
              softWrap: true,
              overflow: TextOverflow.ellipsis,
              overflowWidget: const TextOverflowWidget(
                position: TextOverflowPosition.end,
                align: TextOverflowAlign.center,
                child: Row(
                  mainAxisSize: MainAxisSize.min,
                  children: [
                    Text('\u2026 '),
                    Icon(
                      Icons.add,
                      color: Colors.redAccent,
                    ),
                  ],
                ),
              ),
            ),
          ],
        ),
      ),
    );
  }
}

初始样式：

rebuild后，长文本样式：

再次rebuild后，短文本样式：

其他

ExtendedText 加上key: ValueKey(textName), 即可修复bug。
