例外说明了问题：

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

你也有调用方法：

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)

您必须在这些行检查发生了什么。我们无法调试它，因为我们没有代码。您请求的字段不存在，因此它会引发此异常。
