这是点击文本字段时控制台中的输出。 键盘出现 2 秒后自动隐藏。它也不会抛出任何错误！

Answer 1

GlobalKey<ScaffoldState> _scaffoldKey = new GlobalKey<ScaffoldState>();
final _formKey = GlobalKey<FormState>();
TextEditingController textEditingController = new TextEditingController();


return Scaffold(
  key: _scaffoldKey,
  body : Form(
    key: _formKey,
    child: TextField(
    controller: textEditingController,
    decoration: new InputDecoration(
      hintText: 'Type Your Data',
    ),
  ),
));

或者，如果您使用多个 TextField，则为每个 TextField 使用单独的控制器。我希望这对你有用。
