Updating Nested Data in Flutter Firebase's Firestore database

Question

I need some help updating the following nested data in flutter:

{
  story: [
    0: {
      'views': {
        // Updated DATA here
      }
    },
    1: {
      'views': {
        // Or here
      }
    }
    // Some other data
  ]
}

How can I updated data in firebase using above structure in Flutter?

Answer 1

我认为您在设置新值时需要一个 SetOptions 参数

FirebaseFirestore.instance.collection('...').document(id).set(newObject, SetOptions(merge:true);

Answer 2

使用这种结构，我相信您唯一的选择是先读取数据，在本地更新它，然后使用setData或updateData将其再次保存到 Firestore 中。
