Flutter：如何在文本字段上隐藏光标的 "belly"

Question

每当用户单击文本字段以更改它时，光标就会出现，所以它就是所谓的“肚皮”（我不知道它实际上叫什么，见下图 - 红色箭头）。我想启用交互式选择（即允许将光标移动到文本字段旁边），并在编辑时显示闪烁的光标，但我不希望出现所谓的光标。

这是我的代码：

TextField(
    enableInteractiveSelection: true,
    showCursor: true,
    autofocus: false,
    decoration: InputDecoration(
        isDense: true,
        enabledBorder: OutlineInputBorder(
            borderSide: BorderSide(color: Colors.grey),
            borderRadius: BorderRadius.all(Radius.circular(30))
        ),
        focusedBorder: OutlineInputBorder(
            borderSide: BorderSide(color: Colors.grey),
            borderRadius: BorderRadius.all(Radius.circular(30))
        ),
    ),
    onChanged: (text) => {},
    textAlign: TextAlign.center,
    controller: _firstNameChanged
       ? (_firstNameController..text = _newFirstName)
       : (_firstNameController..text = userRep.firstName),
    inputFormatters: [
       FilteringTextInputFormatter.allow(RegExp('[a-zA-Z]'))
    ],
    focusNode: _firstNameInputFocusNode,
    onSubmitted: (text) {
       if(text.isNotEmpty) {
          setState(() {
            _newFirstName = text;
            _firstNameChanged = true;
          });
       }
    },
    style: GoogleFonts.lato(
       fontSize: 16.0,
       color: Colors.black,
    )
)

有什么想法吗？

Widget build(BuildContext context) {
  return MaterialApp(
    title: 'Flutter Demo',
    theme: ThemeData(
      textSelectionHandleColor: Colors.transparent, /// <- Added
      cursorColor: Colors.lightGreen[800],
      primaryColor: Colors.green,
      accentColor: Colors.lightGreen[800],
      fontFamily: 'NewRomanTimes',

        headline1: TextStyle(fontSize: 72.0, fontWeight: FontWeight.bold),
        headline6: TextStyle(fontSize: 36.0, fontStyle: FontStyle.italic),
      )
    ),
    home: MyHomePage()

}
