flutter_boot

Description:

flutter boot

快速开发Flutter App 的MVI框架、封装Dio网络请求及便捷工具。
功能 #

对生命周期感知的网络请求，基于Dio 封装。
LiveData、ViewModel等实现 MVI
便捷工具及方法拓展。
全局EventBus
InvokeController 组件间状态提升
组件

LayoutOnCreated ：首帧渲染完成回调
OverlayTier : 基于OverlayEntry的弹出层，可设置超时时间。可制作toast 与 弹框。
FadeEffect: 点击组件时有变淡效果。





开始 #
flutter pub add flutter_boot

LiveData #
可观察状态变动
//定义待观察的状态
var liveCounter = LiveData.useState(0);
//使用
liveCounter.watch((count) => Text('$count'))
//更新状态
liveCounter.setState((v) {
liveCounter.value = v + 1;
});

ViewModel #
配合LiveData用于观察多个状态变化。
// 可观察多个状态变化 ， 如果仅观察一个，可使用 SingleLiveDataBuilder
LiveDataBuilder(
//状态，要观察的 view model 的状态
observe: viewModel.stateCounter,
builder: (context,value, child) {
var counterValue = viewModel.stateCounter.value;

return Text(
// 计数
'${counterValue.num}',
style: Theme.of(context)
.textTheme
.headlineMedium
?.copyWith(color: counterValue.color),
);
}),

基础网络请求 #
基于Dio封装的网络请求，简化请求参数。
void _clickRequest() async {
showLoadingDialog(context);
//哔哩哔哩每周必看
var param = Param.url("https://tenapi.cn/v2/{id}")
.tie("num", 120, type: ParamType.query) // query 参数
.tie("id", "weekly", type: ParamType.path); //path 参数

//网络请求
AnHttp.anHttp<String>(param, method: HttpMethodType.get).then((value) {
var jsonMap = jsonDecode(value.data!);
var bili = BaseModel<BiliBili>.fromJson(
jsonMap, (json) => BiliBili.fromJson(json));

if (bili.data != null) {
setState(() {
recordCount = bili.data?.list.length ?? 0;
});
}
dismissLoadingDialog(context);
}).catchError((err) {
print("------err:${err}");
});
}

MVI实现 #
参考样例.

//class _HttpViewModelPageState extends ViewModelState<HttpViewModelPage> {
//或
class _HttpViewModelPageState extends State<HttpViewModelPage>
with ViewModelScope {

late var viewModel = HttpPageViewModel();
var scrollerController = ScrollController();

//ViewModel 初始化
@override
List<ViewModel> useViewModels() {
return [viewModel];
}

Future _onRefresh() async {
viewModel.currentPage = 1;
return viewModel.loadBiliBili();
}
// ...

@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text(widget.title),
),
body: RefreshIndicator(
key: _refreshKey,
onRefresh: _onRefresh,
child: LiveDataBuilder(
observe: viewModel.recordState,// 监听状态
builder: (context,value, child) {
var records = viewModel.recordState.value;
return ListView.separated(...);
})),
);
}

Widget itemWidget(BuildContext context, BiliBiliRecord item, bool last) {
return Container(...);
}
}
