You forgot the question mark after bool condition, read this for Conditional Statement

isBool == false
        ? Container(
            margin: const EdgeInsets.only(right: 15),
            padding: const EdgeInsets.symmetric(horizontal: 10),
            height: 35,
            decoration: BoxDecoration(
              border: Border.all(color: Colors.grey),
              borderRadius: BorderRadius.circular(30),
            ),
            child: Row(
              children: [
                const Expanded(
                  child: Text(
                    'RS-799',
                    style: TextStyle(
                      color: Colors.grey,
                    ),
                  ),
                ),
                Center(
                  child: Icon(
                    Icons.arrow_drop_down,
                    size: 20,
                    color: Colors.red,
                  ),
                ),
              ],
            ),
          )
        : Text('750'),
