The exception says the problem:

Unhandled Exception: Bad state: field does not exist within the DocumentSnapshotPlatform

Also you have the call methods:

E/flutter (25055): #0      DocumentSnapshotPlatform.get._findKeyValueInMap (package:cloud_firestore_platform_interface/src/platform_interface/platform_interface_document_snapshot.dart:86:7)
E/flutter (25055): #1      DocumentSnapshotPlatform.get._findComponent (package:cloud_firestore_platform_interface/src/platform_interface/platform_interface_document_snapshot.dart:104:41)
E/flutter (25055): #2      DocumentSnapshotPlatform.get (package:cloud_firestore_platform_interface/src/platform_interface/platform_interface_document_snapshot.dart:120:26)
E/flutter (25055): #3      _JsonDocumentSnapshot.get (package:cloud_firestore/src/document_snapshot.dart:92:48)
E/flutter (25055): #4      _JsonDocumentSnapshot.[] (package:cloud_firestore/src/document_snapshot.dart:96:40)
E/flutter (25055): #5      _MyHomePageState.getLists (package:form_app/pages/home.dart:518:30)
E/flutter (25055): <asynchronous suspension>
E/flutter (25055): #6      _MyHomePageState._getUnitNamesData (package:form_app/pages/home.dart:495:33)
E/flutter (25055): <asynchronous suspension>
E/flutter (25055): 

You have to check at these rows what happens. We can't debug this because we don't have the code. You ask for a field that is not existing so it throws this exception.
