Now i have two String Variables Name where i want to store title attribute of noteInfo and des where i want to store description attribute of object noteInfo. Data from Firestore is fetched. I just want to store these two attributes in seprate string variables.

CodePudding user response：

As far as I can see in your code, noteInfo is a Map. So you can get the values for those two variables with:

var title = noteInfo["title"];
var description = noteInfo["description"]

To get the data as a map, use:

var noteInfo = snapshot.data!.docs[index].data()! as Map;
