1.2 组合组件：底部弹窗Sheet选择器
/// 直接使用基础组件
testSilBottomPickerWidget() {
return SilBottomSheet.show(
context: context,
child: SilBottomPickerBaseWidget(
child: Container(height: 100, color: Colors.yellow),
));
}

/// 测试时间选择器组件
int initialHours = 8;
int initialMinute = 10;
testSilBottomTimePickerWidget() {
return SilBottomSheet.show(
context: context,
child: SilBottomTimePickerWidget(
'提醒时间',
initialHours: initialHours,
initialMinute: initialMinute,
themeColor: Color.fromRGBO(255, 0, 134, 1),
tapSureSeletedFunc: (int hour, int minute) {
initialHours = hour;
initialMinute = minute;
Navigator.pop(context);
},
));
}

/// 测试时间日期选择器
/// 默认选中的日期和时间
DateTime initialDateTime = DateTime.now();
testSilBottomDatePickerWidget() {
SilBottomSheet.show(
context: context,
child: SilBottomDatePickerWidget('请选择生产日期',
mode: CupertinoDatePickerMode.date,
use24hFormat: true,
themeColor: Color.fromRGBO(255, 0, 134, 1),

}

/// 测试单条数据选择器
List<String> list = ['120', '300', '600', '1200', '18000'];
int selectedIndex = 0;
testSilBottomPickerSimpleWidget() {

Navigator.pop(context);
},
));

/// 底部弹窗菜单
List<String> items = ['相机', '相册'];
SilBottomSheet.show(
context: context,
child: SilBottomSheetWidget(
itemList: items,
warnTitle: '删除',

二、SilFutureBuilderWidget 封装网络异步加载组件
/// SilFutureBuilderWidget 封装网络异步加载组件
/// 可以设置加载时的loading，没有数据时的空页面，网络加载失败的错误页面
/// 使用：
/// 可以使用一个类实现接口方法（例如SilFutureBuilderInterfaceInstanceDefault），定义app的loading、空页面、网络错误页面
/// 也可以在单个页面，重写方法，自定义当前的loading、空页面、网络错误页面
class SilFutureBuilderWidgetDemo extends StatefulWidget {
const SilFutureBuilderWidgetDemo({Key? key}) : super(key: key);

@override
State<SilFutureBuilderWidgetDemo> createState() =>
_SilFutureBuilderWidgetDemoState();
}

class _SilFutureBuilderWidgetDemoState extends State<SilFutureBuilderWidgetDemo>
with SilFutureBuilderInterfaceInstanceDefault {
// 使用with关键字，可以使用SilFutureBuilderInterfaceInstanceDefault中的loading、空页面、网络错误页面实现方法，就可以统一设置，不用每个页面都进行设置了

var _future = null;
List _datas = [];

@override
void initState() {
super.initState();
_future = api_new_apps(); // 接口
}

/// 模拟网络接口
api_new_apps() {
return Future.delayed(Duration(milliseconds: 300), () {
return ['微博', '微信', 'QQ'];
});
}

@override
Widget build(BuildContext context) {
return Scaffold(
backgroundColor: Colors.white,
body: SilFutureBuilderWidget(
future: _future,
mainWidget: (value) {
_datas = value;
return mainWidget();
},
reloadFunc: () {
setState(() {
_future = api_new_apps();
});
},
interface: this // 如果默认的页面不符合app，可以实现接口，自定义loading、空页面、网络错误页面
),
);
}

mainWidget() {
return ListView.separated(
padding: EdgeInsets.symmetric(vertical: 20),
itemBuilder: (context, index) {
return GestureDetector(
onTap: () {},
child: Container(
height: 50,
alignment: Alignment.center,
child: SilText(_datas[index]),
),
);
},
separatorBuilder: (context, index) {
return Padding(padding: EdgeInsets.only(top: 16));
},
itemCount: _datas.length);
}

/// 单个页面，重写方法，自定义当前的网络错误页面
@override
Widget netErrorWidget({void Function()? reloadFunc}) {
return SilNetErrorWidget(reloadFunc: reloadFunc, prompt: 'netErrorWidget');
}

/// 单个页面，重写方法，自定义当前的空页面
@override
Widget noDataWidget(
{RefreshController? emptyRefreshController,
void Function()? reloadFunc}) {
return SilEmptyDataWidget(reloadFunc: reloadFunc);
}
}

三、SilSmartRefresherWidget 封装刷新加载组件
/// SilSmartRefresherWidget 封装刷新加载组件
/// 在SilSmartRefresherWidget的基础上，将刷新处理加了进去，使用时可以只关心接口和ListItem
/// 使用：
/// 如果使用默认组件设置，只需要返回一个接口和列表
/// 也可以用with混合的方式，将app的loading、空页面、网络错误页面、刷新指示器header和footer、是否加载结束设置好
/// 也可以在单个页面，实现SilSmartRefresherInterface的方法，实现单个页面自定义
class SilSmartRefresherWidgetDemo extends StatefulWidget {
const SilSmartRefresherWidgetDemo({Key? key}) : super(key: key);

@override
State<SilSmartRefresherWidgetDemo> createState() =>
_SilSmartRefresherWidgetDemoState();
}

class _SilSmartRefresherWidgetDemoState extends State<SilSmartRefresherWidgetDemo>
with SilFutureBuilderInterfaceInstanceDefault
implements SilSmartRefresherInterface {
List _datas = [];
late RefreshController _refreshController;

@override
void initState() {
super.initState();

_refreshController = RefreshController(initialRefresh: false);
}

/// 模拟网络接口
api_new_apps({int? page}) {
return Future.delayed(Duration(milliseconds: 300), () {
return ['微博', '微信', 'QQ'];
});
}

@override
Widget build(BuildContext context) {
return Scaffold(
backgroundColor: Colors.white,
body: SilSmartRefresherWidget(
childBuild: (context, data) {
_datas = data;
return contentWidget(context);
},
loadDataFuture: ({page, manuallyRefresh}) {
return api_new_apps(page: page);
},
refreshController: _refreshController,
isShowFooterNoData: true,
interface: this,
),
);
}

Widget contentWidget(BuildContext context) {
return ListView.separated(
itemBuilder: (context, index) {
return GestureDetector(
onTap: () {},
child: Container(
height: 50,
alignment: Alignment.center,
child: SilText(_datas[index]),
),
);
},
separatorBuilder: (context, index) {
return Padding(padding: EdgeInsets.only(top: 16));
},
itemCount: _datas.length);
}

/// 单个页面，重写方法，自定义当前的网络错误页面
@override
Widget netErrorWidget({void Function()? reloadFunc}) {
return SilNetErrorWidget(reloadFunc: reloadFunc, prompt: 'netErrorWidget');
}

/// 单个页面，重写方法，自定义当前的空页面
@override
Widget noDataWidget(
{RefreshController? emptyRefreshController,
void Function()? reloadFunc}) {
return SilEmptyDataWidget(reloadFunc: reloadFunc);
}

@override
bool noMoreData({required result, required int loadedDataNum}) {
if (result.data == null) {
return true;
}
return false;
}

@override
Widget refresherFooterWidget() {
return ClassicFooter();
}

@override
Widget refresherHeaderWidget() {
return ClassicHeader();
}
}
