getResultCode method

@override int? getResultCode()

Get the (extended if available) result code.

This might involve parsing the sqlite native message to extract the code See https://www.sqlite.org/rescode.html for the list of result code.

iOS returns normal code while Android/ffi returns extended code for now The application should handle both.

Implementation

@override
int? getResultCode() => _resultCode ??= () {
  final message = _message!.toLowerCase();
  int? findCode(String patternPrefix) {
    final index = message.indexOf(patternPrefix);
    if (index != -1) {
      try {
        // Split at first space
        var code = message
            .substring(index + patternPrefix.length)
            .trim()
            .split(' ')[0];
        // Find ending parenthesis if any
        final endIndex = code.indexOf(')');
        if (endIndex != -1) {
          code = code.substring(0, endIndex);
        }

        final resultCode = int.tryParse(code);
        if (resultCode != null) {
          return resultCode;
        }
      } catch (_) {}
    }
    return null;
  }

  var code = findCode('(sqlite code ');
  if (code != null) {
    return code;
  }
  code = findCode('(code ');
  if (code != null) {
    return code;
  }
  // ios
  code = findCode('code=');
  if (code != null) {
    return code;
  }
  return null;
}();
