flutter - 在颤动中对齐的自定义错误文本

Question

我正在向文本字段添加内容填充。但不需要在错误文本中填充。

child: TextFormField(
              controller: _text,
              keyboardType: widget.inputType,
              onSaved: widget.onSaveData,
              validator: widget.validator,
              decoration: InputDecoration(
                fillColor: _focus_bg,
                filled: true,
                hintText: widget.hintText,
                contentPadding:
                    new EdgeInsets.symmetric(vertical: 10.0, horizontal: 10.0),
                //contentPadding: EdgeInsets.only(left: 11, right: 3, top: 14, bottom: 14),
                errorStyle: TextStyle(fontSize: 12, height: 0.3),

                border:
                    OutlineInputBorder(borderRadius: BorderRadius.circular(10)),
                focusedBorder: OutlineInputBorder(
                    borderRadius: BorderRadius.circular(10),
                    borderSide:
                        new BorderSide(color: AppColor.textBorderFocused)),
              ),
              focusNode: _textFieldFocus,
            ),
