如何使用 firebase 在 flutter 中实现电话号码验证？我的应用程序需要在某个时间验证电话号码。不需要通过电话号码进行身份验证。我只需要验证我的号码。我如何实现它？

我想从 firestore 列出一种数据。每个文档都包含一个“状态”字段。我需要从列表中提取 3 种不同类型的状态。我如何在 dart 中为我的颤振项目做到这一点？

以下代码，它对我不起作用。

getStream() {
  var snapshots = firestore.collection("booking")
  .where("userId", isEqualTo: uid)
  .where("status", isEqualTo: "confirmed")
  .where("status", isEqualTo: "unconfirmed")
  .where("status", isEqualTo: "unconfirmed quotation")
  .snapshots();
  return snapshots;
}

“ Cloud Firestore 覆盖已弃用的 API”

构建颤振应用程序时发生错误。
