显示错误消息时颤振输入字段折叠

Question

我是在手机屏幕的同一行中添加2个输入字段，输入字段在显示错误时折叠。

Row(
children: <Widget>[
  Expanded(
      flex: 2,
      child: TextFormField(
        autovalidateMode: AutovalidateMode
            .onUserInteraction,
        keyboardType: TextInputType.number,
        controller: controller.plz,
        validator: ValidationBuilder(
                localeName: localeLanguage)
            .digits()
            .minLength(5)
            .required()
            .build(),
        decoration: inputdecoration(),
      )),
  SizedBox(width: 10.0),
  Expanded(
      flex: 3,
      child: TextFormField(
        autovalidateMode: AutovalidateMode
            .onUserInteraction,
        validator: ValidationBuilder(
                localeName: localeLanguage)
            .required()
            .build(),
        controller: controller.place,
        decoration: inputdecoration(),
      ))
],
),

输入装饰( errorMaxLines: 3, 帮助文本：''， 内容填充： 新 EdgeInsets.symmetric（垂直：10.0，水平：10.0）， 填充颜​​色：AsianmastaColors.white， 填充：真实， 边框：大纲输入边框（ borderSide: BorderSide(color: Colors.grey, width: 1.0)))

//显示错误后 new

Answer 1

很难阅读代码。首先更新您的问题，在代码块上添加代码。您会在文本键盘上方找到 {} 符号。

Answer 2

给 Row crossAxisAlignment.start 它会起作用

Row(
crossAxisAlignment: CrossAxisAlignment.start
children: <Widget>[
Expanded(
  flex: 2,
  child: TextFormField(
    autovalidateMode: AutovalidateMode
        .onUserInteraction,
    keyboardType: TextInputType.number,
    controller: controller.plz,
    validator: ValidationBuilder(
            localeName: localeLanguage)
        .digits()
        .minLength(5)
        .required()
        .build(),
    decoration: inputdecoration(),
  )),
  SizedBox(width: 10.0),
  Expanded(
  flex: 3,
  child: TextFormField(
    autovalidateMode: AutovalidateMode
        .onUserInteraction,
    validator: ValidationBuilder(
            localeName: localeLanguage)
        .required()
        .build(),
    controller: controller.place,
    decoration: inputdecoration(),
  ))
],
),
