一个flutter表单组件,主要用于处理表单提交业务。

flutter表单组件 #

1 通过简单的集成就可以实现输入、选择等各种类型的表单 #

2 通过check可以检查每个必须提交的表单是否有值,没有则底部提示 errorString #

3 通过getParam可以轻松拿到输入的或着选择等行为产生的值,并按照paramKey作为入参的key获得 #

每一个表单组成的整个字典 #

案例如下:


class _ECFormDemoPage extends ECFormBasePage {
  _ECFormDemoPageVM vm = _ECFormDemoPageVM();

  _ECFormDemoPage({super.key});

  @override
  String? get title => "表单提交";

  @override
  Widget? get leading => Container();

  @override
  Widget? get bottomWidget =>
      TextButton(onPressed: vm.commit, child: const Text("提交"));

  @override
  ECFormBasePageVM get pageVM => vm;
  @override
  setup(BuildContext context) {
    vm.loadData();
    return super.setup(context);
  }
}

class _ECFormDemoPageVM extends ECFormBasePageVM {
  /// 配置cell vm
  loadData() {
    datas.addAll([
      // 输入
      ECFormInputWidgetVM(
        paramKey: 'name',
        value: "不可修改名字",
        title: '名字',
        enable: false,
      ),

      ECFormInputWidgetVM(
        paramKey: 'name1',
        title: '名字',
        checkCall: (out) => out.length >= 2,
        errorString: "至少输入2个字",
      ),

      // 日期
      ECFormDateSelectWidgetVM(paramKey: 'startDate', title: "出发时间"),
      ECFormDateSelectWidgetVM(paramKey: 'endDate', title: "到达时间"),

      // 选择
      ECFormInputSelectWidgetVM(paramKey: 'cardId', title: "车子", selectList: [
        ECFormInputSelectItem(name: "宝马", value: "475993"),
        ECFormInputSelectItem(name: "奔驰", value: "976979")
      ]),

      // 选择(带单位)
      ECFormInputSelectUnitWidgetVM(
          paramKey: 'cardWight',
          title: "车子重",
          keyboardType: TextInputType.number,
          selectedItem: ECFormInputSelectItem(name: "吨", value: "1")),

      // 选择(带可选择单位)
      ECFormInputSelectUnitWidgetVM(
          paramKey: 'cardWight1',
          unitParamKey: "unitCode",
          title: "重量",
          selectedItem: ECFormInputSelectItem(name: "吨", value: "1"),
          unitCanSelect: true,
          keyboardType: TextInputType.number,
          unitSelectList: [
            ECFormInputSelectItem(name: "吨", value: "1"),
            ECFormInputSelectItem(name: "千克", value: "2")
          ]),

      // 备注
      ECFormRemarkWidgetVM(
        title: "添加备注",
        paramKey: 'remark',
        height: 100,
        maxLength: 50,
      ),

      // 展示
      ECFormSectionTitleWidgetVM(title: "大标题")
    ]);

    update();
  }

  commit() {
    // 如果有必选的参数没有值则底部出现红色提示 errorString
    if (!check()) return;

    // 收集的参数param
    Map<String, dynamic> param = getParam();

    debugPrint("收集的参数: ${param.toString()}");
  }
}
