If you have the id of the item in the list you want to delete, you can create a custom action:

// Automatic FlutterFlow imports\nimport '/backend/backend.dart';\nimport '/backend/schema/structs/index.dart';\nimport '/actions/actions.dart' as action_blocks;\nimport '/flutter_flow/flutter_flow_theme.dart';\nimport '/flutter_flow/flutter_flow_util.dart';\nimport '/custom_code/actions/index.dart'; // Imports other custom actions\nimport '/flutter_flow/custom_functions.dart'; // Imports custom functions\nimport 'package:flutter/material.dart';\n// Begin custom action code\n// DO NOT REMOVE OR MODIFY THE CODE ABOVE!\n\nFuture<List<MyDataTypeStruct>> removeFromList(\n  List<MyDataTypeStruct>? arrayList,\n  int id,\n) async {\n\n  /* Remove id from arrayList by id and return arrayList */\n  if (arrayList == null) {\n    return arrayList ?? [];\n  }\n\n  /* find item by index */\n  final index = arrayList.indexWhere((item) => item.id == id);\n\n  /* return list if index == -1 */\n  if (index == -1) {\n    return arrayList;\n  }\n\n  /* remove item by index */\n  arrayList.removeAt(index);\n\n  /* return updated list */\n  return arrayList;\n}

Return value + arguments

I did not tested it, but this should remove a an item with the given id from a list and will return the list without the item
