有这个奇怪的问题,当我点击TextFormField的键盘将冻结或应用程序将崩溃.在IOS的键盘将冻结在Android上,我不能在TextFormField上键入任何内容,我该如何修复它?
如果我从xcode运行相同的代码,textformfield工作正常。
@override
Widget build(BuildContext context) {
return Scaffold(
body: Column(
children: [
Container(
decoration:
const BoxDecoration(color: Color.fromARGB(255, 231, 133, 36)),
height: 8.h,
width: 135.w,
child: Padding(
padding: const EdgeInsets.fromLTRB(8, 40, 0, 0),
child: Row(
children: [
ElevatedButton(
style: ButtonStyle(
backgroundColor: MaterialStateProperty.all(
const Color.fromARGB(255, 62, 84, 122))),
onPressed: () {
setState(() {
_isExpanded = !_isExpanded;
});
},
child: const Text(
'Flight Plan',
style: TextStyle(color: Colors.white),
)),
],
),
),
),
Expanded(
child: Stack(
children: [
Positioned(
top: 0,
left: 0,
// bottom: 0,
child: SizedBox(
height: 67.h,
width: 135.w,
//child: flutterMap(context),
)),
Positioned(
top: -30,
left: 135,
child: AnimatedContainer(
color: const Color.fromARGB(255, 62, 84, 122),
duration: const Duration(milliseconds: 800),
curve: Curves.bounceInOut,
height: 20.h,
width: 100.w,
margin: const EdgeInsets.only(top: 30),
child: Column(
children: [
Row(
mainAxisAlignment: MainAxisAlignment.end,
children: const [
IconButton(
icon: Icon(Icons.skip_previous), onPressed: null),
],
),
Center(
child: Padding(
padding: const EdgeInsets.all(8.0),
child: TextFormField(
autofocus: true,
onChanged: (value) => setState(() {}),
controller: textFieldController,
maxLines: 2,
style:
const TextStyle(decorationColor: Colors.black),
decoration: const InputDecoration(
filled: true,
fillColor: Colors.white,
border: OutlineInputBorder(
borderRadius: BorderRadius.all(
Radius.circular(4.0)))),
),
),
),
],
),
),
),
],
),
),
],
));
}

该死!
class _MyHomePageState extends State<MyHomePage> { bool _isExpanded = false; TextEditingController textFieldController = TextEditingController(); ... }
是分辨率,最初我是在方法内部设置TextEditingController textFieldController = TextEditingController();
的,而不是上面所示的
