So the return value here is not JSON. It is just a list using \\n to escape double-quotes and newlines (\\\" and \\n)

1. \"Sign in\"\n2. \"Login now\"\n3. \"Access account\"\n4. \"Enter credentials\"\n5. \"Authenticate user\"\n6. \"Secure login\"\n7. \"Get started\"\n8. \"Log me in\"\n9. \"Unlock access\"\n10. \"Start session\"

You could start by parsing the whole entry by splitting at the newlines.

List<String> lines = rawList.split('\\n');

then loop over lines. For each line split at the period so you have two entries [\"1\", \"Sign in\"]

use this to build the object array into the JSON

import 'dart:convert';\n\nvoid main() {\n  // Assuming your list is a single string like this\n  String rawList = '''1. \"Sign in\"\n2. \"Login now\"\n3. \"Access account\"\n4. \"Enter credentials\"\n5. \"Authenticate user\"\n6. \"Secure login\"\n7. \"Get started\"\n8. \"Log me in\"\n9. \"Unlock access\"\n10. \"Start session\"''';\n\n  // Splitting the string into lines\n  List<String> lines = rawList.split('\\n');\n  \n  // Extracting the important part from each line and populating a Dart list\n  List<Map<String, dynamic>> parsedList = [];\n  for (String line in lines) {\n    List<String> parts = line.split('. ');\n    if (parts.length == 2) {\n      int number = int.parse(parts[0]);\n      String valuePart = parts[1];\n      String value = valuePart.substring(1, valuePart.length - 1);\n      parsedList.add({\n        'number': number,\n        'value': value,\n      });\n    }\n  }\n\n  // Convert the Dart list to JSON\n  String jsonList = jsonEncode(parsedList);\n  \n  print(\"JSON array: $jsonList\");\n}\n

Stuck at trying to show a JSON String as a List
