Query method not valid
final response = await _db.listDocuments( databaseId: Allconst.databaseId, collectionId: collectionId, queries: [ Query.select(["A", "B"]) ]);
TL;DR
The user is getting an error message stating that the query method is not valid. The error is likely caused by using an incompatible version of the Appwrite cloud, as the current version (1.1.2) does not support the query.select method. The user is advised to check their version of Appwrite and the SDK they are using. The recommended solution is to upgrade to version 1.3 or higher to use the query.select method. 
What version of Appwrite are you using and what version of the SDK are you using?
Btw, it's best to use 3 back ticks with multi-line code. See https://www.markdownguide.org/extended-syntax/#syntax-highlighting
If you are using appwrite cloud..it is not supported yet as the current version is 1.1.2 and the query.select requires min 1.3 version
