TextFormField 获得焦点当前页面被关闭

Question

在我的登录页面中，当任何字段显示焦点键盘并且突然页面立即关闭时，用户名和密码字段都存在。分析发现，只有当我在材质应用程序之前使用 screenutil 包 init 方法时才会发生此问题。如果我删除它，它就可以正常工作。

任何建议都会很有帮助。预先感谢。

app_start.dart 文件：

ScreenUtilInit(
                  designSize: const Size(375, 667),
                  builder: (_, child) {
                    return MaterialApp()
});

登录页面.dart

Form(
      key: model.loginFormKey,
      child: Column(
        children: [
          PrimaryTextField(
            controller: model.emailAddressController,
            label: Strings.of(context).email_address,
            keyBoardType: TextInputType.emailAddress,
            validator: Validator.emailValidator,
          ),
          PrimaryTextField(
            controller: model.passwordController,
            label: Strings.of(context).password,
            validator: Validator.pwdValidator,
          ),
         ]
)
)

主要文本字段

class _PrimaryTextFieldState extends State<PrimaryTextField> {
  ValueNotifier<bool> validateForm = ValueNotifier<bool>(false);

  @override
  Widget build(final BuildContext context) => ValueListenableBuilder<bool>(
        valueListenable: validateForm,
        builder: (
          context,
          listenValue,
          child,
        ) {
          return TextFormField(
            focusNode: widget.focusNode,
            autocorrect: false,
            maxLines: widget.maxLines ?? 1,
            controller: widget.controller,
            onChanged: (value) {
              validateForm.value =
                  widget.validator!(widget.controller.text) != null;
            },

我正在使用带有 mvvm 的干净架构，因此我的模型文件中有 textformfield，因此我尝试将其移至状态类内部。我尝试更改屏幕实用程序的设计尺寸仍然没有区别。

我通过重建从 API 接收数据的对象来修复它，问题是我忘记了 API 上的地图之间有列表， 如果您有同样的错误，我不会，但您可以检查您创建的 API 和模型并确保
