Flutter TextField 键盘类型在 ios 上不起作用

Question

键盘类型属性不会改变 ios 键盘的外观。它在 android 上运行良好，在 ios 上也正常工作，直到它突然开始显示相同的键盘，而不管在文本字段上设置键盘类型属性。

这是文本字段：

TextFormField(
                  keyboardType: TextInputType.emailAddress,
                  initialValue: _loginValues['email'],
                  focusNode: _emailFocusNode,
                  textInputAction: TextInputAction.next,
                  onFieldSubmitted: (_) => FocusScope.of(context)
                      .requestFocus(_passwordFocusNode),
                  validator: (value) {
                    if (value.isEmpty) {
                      return 'Agrega un correo electronico por favor';
                    }
                    return null;
                  },
                  onSaved: (value) {
                    _loginValues['email'] = value;
                  },
                  cursorColor: Theme.of(context).accentColor,
                  
                ),

显示的键盘是这样的：用于电子邮件输入的键盘 键盘

另外，无论我设置什么键盘属性，我都会得到相同的键盘
