有没有办法在我使用flutter设计的聊天应用中自动滚动到新消息

ListView(
  physics: AlwaysScrollableScrollPhysics(),
  controller: _scrollController,
  children: <Widget>[
    // 列表项
  ],
)

ScrollController _scrollController = ScrollController();

@override
void initState() {
  super.initState();
  // 初始化ScrollController
  _scrollController = ScrollController();
}

void scrollToBottom() {
  _scrollController.animateTo(
    _scrollController.position.maxScrollExtent,
    duration: Duration(milliseconds: 300),
    curve: Curves.easeOut,
  );
}

// 示例代码
void onNewMessageArrived() {
  // 处理新消息到达的逻辑
  // ...

  // 滚动到最新消息
  scrollToBottom();
}
