在Flutter中，当输入的文本长度超过字段长度时，文本将隐藏，如gif中所示：

第一个文字表单字段的程式码：

Column(
                      crossAxisAlignment: CrossAxisAlignment.start,
                      children: [
                        labelFormStyle("Nome do equipamento"),
                        Container(
                          height: hasErrorForm && equipmentNameController.text.isEmpty ? 55 : 35,
                          child: Container(
                          height: hasErrorForm && equipmentNameController.text.isEmpty ? 55 : 35,
                          child: TextFormField(
                            validator: (value){
                              return validatorEmpty(value);
                            },
                            controller: equipmentNameController,
                            keyboardType: TextInputType.multiline,
                            maxLines: null,
                            textInputAction: TextInputAction.next,
                            style: TextStyle(
                                fontSize: 14
                            ),
                            decoration: InputDecoration(
                                isDense: true,
                                enabledBorder: enableBorderField(),
                                focusedBorder: enableBorderField(),
                                disabledBorder: enableBorderField(),
                                border: enableBorderField(),
                                focusedErrorBorder: errorBorderField(equipmentNameController.text.isEmpty),
                                errorBorder: errorBorderField(equipmentNameController.text.isEmpty)
                            ),
                            onChanged: (value){
                              if(hasErrorForm){
                                setState(() {
                                  _formKey.currentState!.validate();
                                });
                              }
                            },
                          ),
                        ),
                      ],
                    ),

这怎么解决？
