flutter - SetOptions 在 Firestore Flutter WEB 中不起作用

Question

查看 Flutter Web。似乎 Firestore Flutter Web 集成还不完善。 试图传递 {merge: true} 参数:

webFirestore
    .collection("/users")
    .doc(uid)
    .set(map, {merge: true});

{merge: true} 带有红线下划线。尝试了不同的格式，都没有用。 有谁知道语法应该是什么样子？

这就是 firestore 文档所说的:

/// An object to configure the [WriteBatch.set] behavior.
/// Pass [: {merge: true} :] to only replace the values specified in
/// the data argument. Fields omitted will remain untouched.
@anonymous
@JS()
abstract class SetOptions {
  /// Set to true to replace only the values from the new data.
  /// Fields omitted will remain untouched.
  external bool get merge;
  external set merge(bool v);
  external factory SetOptions({bool merge});
}

遇到了同样的问题，我相信这是可行的:

webFirestore
    .collection("/users")
    .doc(uid)
    .set(map, SetOptions(merge: true));
