The following NoSuchMethodError was thrown building: Class 'QuerySnapshot' has no instance method 'call'. Receiver: Instance of 'QuerySnapshot' Tried calling: call()

When the exception was thrown, this was the stack: #0 Object.noSuchMethod (dart:core-patch/object_patch.dart:51:5) #1 _HomekitchenListState.build..

Please reduce this to a smaller piece of code that fails similarly, or point out what you've tried for debugging. Can you mark the lines that are being described in the stack trace? — Randal Schwartz
DocumentSnapshot homekitchens = snapshot.data().docs[index]; - here data() should be changed to data. — Muthu Thavamani
