Hello, My project contains many custom actions. Recently, the following error suddenly occurs without reason. If I delete the action that causes the error, it then points to the next action:
Unexpected null value.
The relevant error-causing widget was: IndexPageWidget
Stack trace:
dart:sdk_internal 11994:11 throw_ dart:sdk_internal 12343:30 nullCheck packages/study_languages/custom_code/actions/process_folder_edit.dart.js 40236:28 <fn> package/study_languages/custom_code/actions/process_folder_edit.dart.js 40263:19 build
Even after commenting out the problematic process_folder_edit custom action, the same error persists, and deleting the action just causes the error to appear with the next action.
How can I resolve this issue?
