I just solved it by adding longpress event

TextFormField(
                  obscuringCharacter: '#',
                  obscureText: passwordVisible,
                  controller: password,
                  decoration: InputDecoration(
                    suffixIcon: GestureDetector(
                      child: IconButton(
                        icon: const Icon(Icons.remove_red_eye),
                        onPressed: () {
                        },
                      ),
                      onLongPressEnd: (LongPressEndDetails Details){
                        setState(() {
                          passwordVisible = true;
                        });
                      },
                      onLongPress: () {
                        setState(() {
                          passwordVisible = false;
                        });
                      },

                    ),
