一、效果图

二、主要代码

import 'package:company_manage_flutter/xcClass/dicDataProp.dart';
import 'package:flutter/material.dart';
import 'package:get/get.dart';class CheckListWidget extends StatefulWidget {final List<Map<String, dynamic>> list;final Function? onChanged;final DicDataProp props;Map<String, dynamic>? initValue;CheckListWidget({super.key,required this.list,this.onChanged,this.props = const DicDataProp(),this.initValue});@overrideState<CheckListWidget> createState() => CheckListWidgetState();
}class CheckListWidgetState extends State<CheckListWidget> {RxMap<String, dynamic> selected = <String, dynamic>{}.obs;@overridevoid initState() {// TODO: implement initStatesuper.initState();selected.value = widget.initValue ?? {};}@overrideWidget build(BuildContext context) {return buildCheckList(widget.list, widget.onChanged, props: widget.props);}void test() {print('test-组件内的方法');}//单选列表Widget buildCheckList(List<Map<String, dynamic>> list, Function? onChanged,{DicDataProp? props}) {String label = props?.label ?? 'label';String value = props?.value ?? 'value';return Obx(() => Container(width: Get.width,child: Column(children: list.asMap().entries.map((entry) {int index = entry.key;dynamic item = entry.value;return Column(children: [GestureDetector(onTap: () {selected?.value = item;if (onChanged != null) {onChanged(item);}},child: Container(width: Get.width,decoration: BoxDecoration(color: Colors.blue.withOpacity(0),),padding: const EdgeInsets.symmetric(vertical: 16, horizontal: 16),child: Row(children: [Icon((selected?.value[value] ?? '') == item[value]? Icons.check_circle: Icons.circle_outlined,size: 22,color:(selected?.value[value] ?? '') == item[value]? Color.fromRGBO(50, 73, 223, 1): Color.fromRGBO(21, 23, 30, 0.40)),SizedBox(width: 6),Text(item[label] ?? "",style: TextStyle(fontSize: 16,),),],),)),Divider(height: 1,color: index + 1 == list.length? Color.fromRGBO(128, 130, 145, 0): Color.fromRGBO(128, 130, 145, 0.20),),],);}).toList(),)));}
}

三、使用

//CheckListWidgetState 不能已下划线开头，因为_开头是私有的，不能在其他文件中访问final checkListWidgetKey = GlobalKey<CheckListWidgetState>();CheckListWidget(key: checkListWidgetKey,list: bottomSheetList,onChanged: (value) {print("CheckListWidget:${value}");},initValue: const {'id': '18', 'name': '仓库1'},props: DicDataProp(label: 'name', value: 'id'),),buildButtonWidget('调用组件的方法、获取值', onPressed: () {print('调用组件的方法、获取值 = ${checkListWidgetKey.currentState?.selected}');checkListWidgetKey.currentState?.test();}),
