Question

嘿，伙计们，我需要你们的帮助，我已经尝试让它工作了一段时间，但它是否找到了我错的地方，这里是代码，所以你们可以看到。

Widget build(BuildContext context) {
SystemChrome.setEnabledSystemUIOverlays([]);
SizeConfig().init(context);
return Scaffold(
  appBar: AppBar(
    elevation: 20,
    actions: [
      Padding(
        padding: EdgeInsets.only(right: SizeConfig.defaultSize * 3),
        child: MyProfile.routeName != '/my-profile'

      ),
      Expanded(
        child: new TabBarView(
          controller: _controller,
          children: <Widget>[

            komentari(),
          ],
        ),
      ),
    ],
  ),
);

}

Widget komentari() {
return Column(
  children: [
    Expanded(
      child: ListView(
        children: [
          CommentWidget(),
          CommentWidget(),
          CommentWidget(),
          CommentWidget(),
          CommentWidget(),
          CommentWidget(),
        ],
      ),
    ),
    TextField(
      maxLines: 2,
      textCapitalization: TextCapitalization.sentences,
      autocorrect: false,
      keyboardType: TextInputType.text,
      onSubmitted: (value) {
        _komentarProfilaText = value;
        _komentar.clear();
      },
      focusNode: _focusNodeKomentariProfil,
      controller: _komentar,
      decoration: InputDecoration(
        hintText: "Dodaj komentar...",
        contentPadding: EdgeInsets.only(
            left: SizeConfig.defaultSize * 1.5,
            top: SizeConfig.defaultSize * 1.5),
        fillColor: Colors.white,
      ),
    ),
  ],
);

}

这是怎么回事

我想要实现的是将 TextField 置于键盘顶部，但我不想滚动页面。如果可能的话，像这样的事情。

Flutter TextField 底部溢出 TabBar
