ec form
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()}");
}
