Allowed Params Error due to Instance of Variable<String>

     await batch((Batch b) async {
        for (final Map<String, dynamic> json in list) {
          final String verseId = json['verse_id'].toString();
          final String bookId = json['book_id'].toString();
          final String verseChapter = json['verse_chapter'].toString();
          final String verseNumber = json['verse_number'].toString();
          final String verseText = json['verse_text'].toString();
          final String isRed = json['is_red'].toString();
          final String bookName = json['book_name'].toString();
         b.customStatement(
                  'INSERT INTO $verseTable (verse_id, book_id,verse_chapter,verse_number, '
                  'verse_text,is_red,book_name) VALUES(?,?,?,?,?,?,?)',
                 [
                    Variable.withString(verseId),
                    Variable.withString(bookId),
                    Variable.withString(verseChapter),
                    Variable.withString(verseNumber),
                    Variable.withString(verseText),
                    Variable.withString(isRed),
                    Variable.withString(bookName),
                  ]);      
        }

I am using Drift to do a custom statement, the custom insert with just $variables bails out due to " quotes in the strings. The above throws the drift error:

flutter: [2024-01-23T10:08:51.467958] Invalid argument (params[1]): Allowed parameters must either 
be null or bool, int, num, String or List<int>.: Instance of 'Variable<String>'

If I remove Variable.withString() and just put the variable it won't work due to the quotes
Is there a 'prepare' type statement in dart I can use instead of the Variable.withString() method?

After removing the Variable.withstring() and leaving just the variables in the List, it worked.

Yes, Variable is used by the Dart query builder which you're sidestepping here. So you can just use the underlying value without wrapping it in Variable.
