How do I center the posts in the widget I created?

Question

TextField textWidget(String text, IconData icon, bool isPasswordType,
    TextEditingController controller, TextAlign align) {
  return TextField(
    controller: controller,
    obscureText: isPasswordType,
    enableSuggestions: !isPasswordType,
    autocorrect: !isPasswordType,
    cursorColor: Colors.white,
    style: TextStyle(color: Colors.white.withOpacity(0.9)),
    decoration: InputDecoration(
      prefixIcon: Icon(
        icon,
        color: Colors.white70,
      ),
      labelText: text,
      labelStyle: TextStyle(color: Colors.white.withOpacity(0.9)),
      filled: true,
      floatingLabelBehavior: FloatingLabelBehavior.never,
      fillColor: const Color.fromARGB(255, 209, 107, 107).withOpacity(0.7),
      border: OutlineInputBorder(
          borderRadius: BorderRadius.circular(30.0),
          borderSide: const BorderSide(width: 0, style: BorderStyle.none)),
    ),
    keyboardType: isPasswordType
        ? TextInputType.visiblePassword
        : TextInputType.emailAddress,
  );}

I created a widget called textWidget and it's;

child: textWidget(
  "Mail Adress",
   Icons.people_alt_outlined,
   false,
   _numberController,
   TextAlign.center),

I tried to add it like this. I call in textWidget;

(String text, IconData icon, bool isPasswordType,TextEditingController controller, TextAlign align)

I assigned all the values ​​as seen in the second code. However, this did not bring the articles to the middle of the label.

You can use label to place Text widget instead of labelText

  decoration: InputDecoration(
        label: Center(
          child: Text(
            text,
            style: TextStyle(
              color: Colors.white.withOpacity(0.9),
            ),
          ),
        ), 

 TextField textWidget(String text, IconData icon, bool isPasswordType,
      TextEditingController controller, TextAlign align) {
    return TextField(
      controller: controller,
      obscureText: isPasswordType,
      enableSuggestions: !isPasswordType,
      autocorrect: !isPasswordType,
      cursorColor: Colors.white,
      textAlign: TextAlign.center,
      style: TextStyle(color: Colors.white.withOpacity(0.9)),
      decoration: InputDecoration(
        label: Center(
          child: Text(
            text,
            style: TextStyle(
              color: Colors.white.withOpacity(0.9),
            ),
          ),
        ),
        prefixIcon: Icon(
          icon,
          color: Colors.white70,
        ),
        filled: true,
        floatingLabelBehavior: FloatingLabelBehavior.never,
        fillColor: const Color.fromARGB(255, 209, 107, 107).withOpacity(0.7),
        border: OutlineInputBorder(
            borderRadius: BorderRadius.circular(30.0),
            borderSide: const BorderSide(width: 0, style: BorderStyle.none)),
      ),
      keyboardType: isPasswordType
          ? TextInputType.visiblePassword
          : TextInputType.emailAddress,
    );
  }
