Flutter TextFormField无法输入 软键盘弹出即消失问题求助

问题现象 #

• 未对业务代码做任何修改的前提下，项目中InputField输入框无法输入任何内容
• 点击输入框时软键盘弹出后会立刻消失
• 已尝试各类常规排查方案，哪怕是结构最简的输入框依然无法正常工作
• 待确认点：是否需要在Android端做额外配置，问题是否由框架/SDK版本更新导致

对应STORequestScreen页面实现代码 #

class STORequestScreen extends StatefulWidget {
  final List<String> locationData;
  final List<String> structureCodes;

  STORequestScreen(
      {Key? key, required this.locationData, required this.structureCodes})
      : super(key: key);

  @override
  _STORequestScreenState createState() => _STORequestScreenState();
}

class _STORequestScreenState extends State<STORequestScreen> {
  List<String> locations = [];
  List<String> structureCodes = [];

  @override
  void initState() {
    super.initState();
    locations = widget.locationData;
    structureCodes = widget.structureCodes;
    EasyLoading.dismiss();
  }

  @override
  Widget build(BuildContext context) {
    return Container(
        child: ListView(shrinkWrap: true, children: [
      CustomAppBar(),
      const SizedBox(
        height: 10,
      ),
      const Align(
        alignment: Alignment.center,
        child: Text("STO Request",
            style: TextStyle(fontSize: 18, fontWeight: FontWeight.w500)),
      ),
      const SizedBox(
        height: 10,
      ),
      const Padding(
        padding: EdgeInsets.only(left: 10, bottom: 20),
        child: Align(
          alignment: Alignment.centerLeft,
          child: Text("Details",
              style: TextStyle(fontSize: 16, fontWeight: FontWeight.bold)),
        ),
      ),
      TextFormField(
        decoration: InputDecoration(labelText: 'Location'),
      )
    ]));
  }
}

点击TextFormField时抓取的控制台运行日志 #
