你应该选择ListView.builder()，因为它可以按需创建项目。
示例：

child: ListView.builder(
  reverse: true,
  scrollDirection: Axis.vertical,
  padding: const EdgeInsets.only(top: 35, bottom: 25),
  itemCount: messages.length,
  controller: controller,
  itemBuilder: (context, index) {
    return ChatBubble(
      time: messages[index].time,
      chatPartner: chatPartner,
      message: messages[index].message,
      isMe: messages[index].sentBy != cId ? true : false,
    );
  },
),
