I want the Icon (inside the searchbar in suffix Icon) to be shown after the Search Bar

Here's what I've tried but doesn't work:

• When both are placed in a row, it doesnt show up
• When I place the row in Expanded, same issue
• Suffixicon places the icon in the border, I want it outside the border
• I have also tried Suffix instead of suffix icon but no luck

Try below code hope its help to you. I have just change your searchbar widget if you want to display your suffixIcon just add it afer texrfield

//SEARCHBAR
              Row(
                children: [
                  Expanded(
                    child: Padding(
                      padding: const EdgeInsets.all(8.0),
                      child: TextFormField(
                        // controller: textIDController,
                        style: const TextStyle(
                            color: Colors.black, fontWeight: FontWeight.w700),
                        decoration: InputDecoration(
//                           suffixIcon: Icon(
//                             Icons.filter_list_sharp,
//                             size: 30,
//                             color: Colors.black,
//                           ),
                          labelText: "Search",
                          labelStyle: const TextStyle(
                              color: Colors.black, fontWeight: FontWeight.w700),
                          // fillColor: Colors.white,
                          focusedBorder: OutlineInputBorder(
                            borderRadius: BorderRadius.circular(20),
                            borderSide:
                                const BorderSide(color: Colors.black, width: 2.0),
                          ),
                          enabledBorder: OutlineInputBorder(
                            borderRadius: BorderRadius.circular(20),
                            borderSide:
                                const BorderSide(color: Colors.black, width: 2.0),
                          ),
                        ),
                        maxLines: 1,
                        keyboardType: TextInputType.text,
                        textInputAction: TextInputAction.next,
                      ),
                    ),
                  ),
                  SizedBox(width: 5,),// adjust width between search box and icon here as per your need
                  Icon(
                            Icons.filter_list_sharp,
                            size: 30,
                            color: Colors.black,
