How to Fix Dropdown Button Text Alignment Issue?

Question

I have created two dropdown buttons in my Flutter app, and I want them to look the same. Problem the text inside the hint of the second dropdown button is not showing correctly, creating a visual difference. How can I make sure the text in the second dropdown button aligns properly and looks like the first one?

First DropDownButton Widget Code:

DropdownButtonFormField<String>(
                            isExpanded: true,
                            decoration: InputDecoration(
                              hoverColor: Colors.green,
                              filled: true,
                              fillColor: CupertinoColors.systemGrey4,
                              contentPadding:
                                  const EdgeInsets.symmetric(vertical: 12),
                              border: OutlineInputBorder(
                                borderSide: BorderSide.none,
                                borderRadius: BorderRadius.circular(32),
                              ),
                            ),
                            hint: Text(
                              'İşlem Yapılan Hisse Sayısı',
                              textAlign: TextAlign.center,
                              style: (buildJosefinSans(0.5, 16)),
                            ),
                            items: list
                                .map((item) => DropdownMenuItem<String>(
                                      value: item.toString(),
                                      child: Align(
                                          alignment: Alignment.center,
                                        child: Text(
                                          item.toString(),
                                          textAlign: TextAlign.center,
                                        ),
                                      ),
                                    ))
                                .toList(),
                            validator: (value) {
                              if (value == null) {
                                return 'İşlem Yapılan Hisse Sayısı';
                              }
                              return null;
                            },
                            onChanged: (value) {
                            },
                            onSaved: (value) {
                              selectedValue = value.toString();
                            },
                            buttonStyleData: const ButtonStyleData(
                              padding: EdgeInsets.only(right: 8),
                            ),
                            iconStyleData: const IconStyleData(
                              icon: Icon(
                                Icons.keyboard_arrow_down_sharp,
                                color: Colors.black,
                              ),
                              iconSize: 32,
                            ),
                            dropdownStyleData: DropdownStyleData(
                              decoration: BoxDecoration(
                                color: CupertinoColors.systemGrey5,
                                borderRadius: BorderRadius.circular(15),
                              ),
                            ),
                            menuItemStyleData: const MenuItemStyleData(

Second DropDownButton Widget Code:
