getData method
Retrieves data from a specified document within a collection.
The collectionName
specifies the collection and docName
specifies the document
from which data is to be fetched. Returns a map of the data if the document exists.
Implementation
Future<Map<String, dynamic>> getData(
String collectionName, String docName) async {
DocumentSnapshot docSnapshot =
await obj.collection(collectionName).doc(docName).get();
if (docSnapshot.data() != null) {
Map<String, dynamic> data = docSnapshot.data() as Map<String, dynamic>;
print(data);
return data;
}
return {};
}
