當(dāng)我的文本輸入框的下拉按鈕換成芯片平鋪后盆佣，想要在手機(jī)鍵盤點(diǎn)擊下一個(gè)按鈕后跳轉(zhuǎn)到下一個(gè)文本框辈毯，但是文本框下面有了組件（芯片組件warp，或button組件）后乙埃，就無(wú)法自動(dòng)跳轉(zhuǎn)闸英。
百度后得到一個(gè)方法，但不適用于我循環(huán)數(shù)據(jù)介袜，改裝成先判斷輸入框個(gè)數(shù)甫何，再通過(guò)循環(huán)向自定義的List數(shù)組里添TextEditingController()值。

官方有對(duì)應(yīng)的focus小部件遇伞，但是我放到我的view里面不執(zhí)行辙喂，沒(méi)時(shí)間去調(diào)試了，有時(shí)間研究的可以去試下鸠珠，文檔里說(shuō)直接用FocusNode進(jìn)行管理很少見(jiàn) 傳送門

1.百度到（flutter textInputAction.next焦點(diǎn)被下面的組件擋准优伞）

class _MyFormState extends State<MyForm> {
  final List<TextEditingController> _controllers = 
    List.generate(3, (index) => TextEditingController());
  final List<FocusNode> _focusNodes = 
    List.generate(3, (index) => FocusNode());
 
  @override
  void dispose() {
    for (var controller in _controllers) {
      controller.dispose();
    }
    for (var focusNode in _focusNodes) {
      focusNode.dispose();
    }
    super.dispose();
  }
 
  @override
  Widget build(BuildContext context) {
    return Column(
      children: _controllers.asMap().entries.map((entry) {
        var controller = _controllers[entry.key];
        var focusNode = _focusNodes[entry.key];
        var isLastField = entry.key == _controllers.length - 1;
        return TextField(
          controller: controller,
          focusNode: focusNode,
          textInputAction: isLastField ? TextInputAction.done : TextInputAction.next,
          onSubmitted: (value) {
            if (isLastField) {
              focusNode.unfocus();
            } else {
              FocusScope.of(context).requestFocus(_focusNodes[entry.key + 1]);
            }
          },
        );
      }).toList(),
    );
  }
}

2.適用于我自己

class XxxxxxView extends GetView<XxxxxxController> {
  List<TextEditingController> _controllers = [];
  List<FocusNode> _focusNodes = [];
  bool shouldContinue = true; //控制循環(huán)變量

@override
  Widget build(BuildContext context) {
    return Container(
      child: GetBuilder<SamplingRecordController>(builder: (ctx) {
        return  ListView(
          children: [
            _buildCyDateInput(),
            _buildCyTimeInput(),
            ..._buildItemByConfig(context),
          ],
        );
      }),
    );
  }

/// 根據(jù)配置顯示填寫的信息
  List<Widget> _buildItemByConfig(BuildContext context) {
    List<Widget> list = [];
    Map<String, dynamic> config =
        ObjectUtil.isNotEmpty(controller.xx['xx'])
            ? controller.xx['xx']
            : Map();
    int i = 0;
    int j = 1;

    if(shouldContinue){  //頁(yè)面熱更新后會(huì)向數(shù)組重復(fù)添加一組數(shù)據(jù)，添加狀態(tài)判斷
      config.forEach((key, configValue) {
          j++;
          if(xx){

          }else{
            _controllers.add(TextEditingController());
            _focusNodes.add(FocusNode());
          }
          if (j > config.length) {
            // 設(shè)置標(biāo)志變量為false來(lái)跳出外層循環(huán)
            shouldContinue = false;
            return; // 跳出當(dāng)前內(nèi)層循環(huán)
          }
      });
    }

    config.forEach((key, configValue) {
        list.add(
            Column(
                children: [
                  ListTile(
                    title: _buildConfigItemInput(context,configValue, i),
                  ),
                  _buildConfigItemChip(context,configValue) //芯片
                ],
              )
          );
          ++i;
    });
    return list;
  }

  _buildConfigItemInput(BuildContext context, dynamic configValue, int i) {
    var textController =  _controllers[i];  //獲取對(duì)應(yīng)鍵值
    var textNode =  _focusNodes[i];
    var isLastField = i == _controllers.length - 1; //獲取是否最后一個(gè)

    return GetBuilder<SamplingRecordController>(builder: (ctx) {
      return GestureDetector(
        onTap: () async {
        },
        child: Column(
          children: [
            Row(
              children: [
                Expanded(

                    enabled: enabledStatus,
                    autofocus: false,  //必須設(shè)置為false跳芳，不然會(huì)和focusNode焦點(diǎn)沖突，自動(dòng)關(guān)閉會(huì)上滑仍然打開(kāi)
                    obscureText: false,
                    keyboardType: configValue['inputmode'] == 'number'
                        ? TextInputType.number
                        : TextInputType.text,
                    maxLines: null,
                    focusNode: textNode,
