前言

離上篇文章介紹OpenGit_Flutter已通過了兩個月，在兩個月期間完成了v1.1.0、v1.2.0以及下文立刻介紹的v1.3.0版本，點擊見版本更新記錄。在v1.3.0版本中，對總體UI作了修改，採用卡片式風格；對登陸界面作了改版，UI主要參考flutter-ui-nice；優化了編輯issue、評論相關邏輯，並增長標籤功能；改版了我的資料頁面，並增長組織相關邏輯，UI主要參考flutter-ui-nice；增長了分享功能等。v1.3.0版本相比較之前的版本，體驗上作了較大的改動，下面一一介紹該客戶端涉及到的相關內容。javascript

該項目涉及到的主要架構，能夠參考MVC、MVP、BloC、Redux四種架構在Flutter上的嘗試。html

項目中卡片式風格的主要代碼以下所示java

InkWell(
      child: Padding(
        padding: const EdgeInsets.all(8.0),
        child: _postCard(context, item),
      ),
      onTap: () {
        NavigatorUtil.goWebView(context, item.title, item.originalUrl);
      },
)

Widget _postCard(BuildContext context) {
    return Card(
      elevation: 2.0,
      child: ......
    );
}
複製代碼

程序入口

void main() {
  final store = Store<AppState>(
    appReducer,
    initialState: AppState.initial(),
    middleware: [
      LoginMiddleware(),
      UserMiddleware(),
      AboutMiddleware(),
    ],
  );

  runZoned(() {
    runApp(OpenGitApp(store));
  }, onError: (Object obj, StackTrace trace) {
    print(obj);
    print(trace);
  });
}
複製代碼

程序入口main方法內，進行了redux相關初始化操做，並啓動了OpenGitApp頁面。而runZoned是爲了在運行環境內捕獲全局異常等信息，便於分析問題。node

下面看下OpenGitApp頁面的相關代碼，具體代碼以下所示react

class OpenGitApp extends StatefulWidget {
  final Store<AppState> store;

  OpenGitApp(this.store) {
    final router = Router();

    AppRoutes.configureRoutes(router);

    Application.router = router;
  }

  @override
  State<StatefulWidget> createState() {
    return _OpenGitAppState();
  }
}
複製代碼

在OpenGitApp構造函數內，完成了Fluro路由的相關初始化操做，關於Fluro後續會補充文章介紹。而閃屏頁的定義以下面代碼所示git

static final splash = '/';

router.define(
    splash,
    handler: splashHandler,
    transitionType: TransitionType.cupertino,
);

var splashHandler = Handler(
    handlerFunc: (BuildContext context, Map<String, List<String>> params) {
  return SplashPage();
});
複製代碼

當OpenGitApp相關頁面初始化功能加載完成後，默認會啓動SplashPage頁面，同時_OpenGitAppState類中，會進行相關數據的初始化功能，以下面代碼所示github

class _OpenGitAppState extends State<OpenGitApp> {
  static final String TAG = "OpenGitApp";

  @override
  void initState() {
    super.initState();
    widget.store.dispatch(InitAction());
  }
 }
複製代碼

在initState中發起redux初始化數據指令InitAction，當指令發出後，UserMiddleware會收到該指令，並對該指令作相應的處理，以下面代碼所示web

Future<Null> _init(Store<AppState> store, NextDispatcher next) async {
    //完成sp的初始化
    await SpUtil.instance.init();

    //初始化數據庫，並進行刪除操做
    CacheProvider provider = CacheProvider();
    await provider.delete();

    //主題
    int theme = SpUtil.instance.getInt(SP_KEY_THEME_COLOR);
    if (theme != 0) {
      Color color = Color(theme);
      next(RefreshThemeDataAction(AppTheme.changeTheme(color)));
    }
    //語言
    int locale = SpUtil.instance.getInt(SP_KEY_LANGUAGE_COLOR);
    if (locale != 0) {
      next(RefreshLocalAction(LocaleUtil.changeLocale(store.state, locale)));
    }
    //用戶信息
    String token = SpUtil.instance.getString(SP_KEY_TOKEN);
    UserBean userBean = null;
    var user = SpUtil.instance.getObject(SP_KEY_USER_INFO);
    if (user != null) {
      LoginManager.instance.setUserBean(user, false);
      userBean = UserBean.fromJson(user);
    }
    LoginManager.instance.setToken(token, false);
    //引導頁
    String version =
        SpUtil.instance.getString(SP_KEY_SHOW_GUIDE_VERSION);
    String currentVersion = Config.SHOW_GUIDE_VERSION;
    next(InitCompleteAction(token, userBean, currentVersion != version));
    //初始化本地數據
    ReposManager.instance.initLanguageColors();
}
複製代碼

閃屏頁

閃屏頁

當進入到閃屏頁後，經過redux啓動頁面的倒計時操做，以下面代碼所示數據庫

store.dispatch(StartCountdownAction(context));
複製代碼

當發出倒計時指令後，UserMiddleware會收到該指令，並對該指令作相應的處理，以下面代碼所示redux

void startCountdown(
      Store<AppState> store, NextDispatcher next, BuildContext context) {
    TimerUtil.startCountdown(5, (int count) {
      next(CountdownAction(count));

      if (count == 0) {
        _jump(context, store.state.userState.status,
            store.state.userState.isGuide);
      }
    });
}
複製代碼

經過TimerUtil啓動一個5s的倒計時，並將倒計時的時間點同步給SplashPage頁面，用來刷新倒計時時間，TimerUtil工具類不作過多介紹，細節能夠參考OpenGit_Flutter項目經常使用公共庫總結。當倒計時跑完以後，會經過用戶初始化數據狀態，進行頁面跳轉操做，以下面代碼所示

void _jump(BuildContext context, LoginStatus status, bool isShowGuide) {
    if (isShowGuide) {
      NavigatorUtil.goGuide(context);
    } else if (status == LoginStatus.success) {
      NavigatorUtil.goMain(context);
    } else if (status == LoginStatus.error) {
      NavigatorUtil.goLogin(context);
    }
}
複製代碼

當用戶是首次操做應用時，則跳轉到引導頁；若是已登陸，則跳轉主頁，若是未登陸；則跳轉登陸頁。

引導頁

引導頁

引導頁相關代碼參考flutter_gallery裏的animation，這裏不作過大介紹。當點擊當即體驗時，相關代碼以下所示

void _onExperience(BuildContext context) {
    Store<AppState> store = StoreProvider.of(context);
    LoginStatus status = store.state.userState.status;
    if (status == LoginStatus.success) {
      NavigatorUtil.goMain(context);
    } else if (status == LoginStatus.error) {
      NavigatorUtil.goLogin(context);
    }
}
複製代碼

首先經過redux查詢用戶的登陸狀態，若是已登陸，則跳轉主頁，若是未登陸；則跳轉登陸頁。

登陸頁

登陸頁

登陸過程分爲受權和獲取用戶資料，涉及到的api以下所示

  • 受權api

    POST /authorizations

  • 獲取用戶資料api

    GET /user

當用戶沒有帳號時，能夠進行帳號的註冊，以下面代碼所示

NavigatorUtil.goWebView(
    context,
    AppLocalizations.of(context).currentlocal.sign_up,
    'https://github.com/');
複製代碼

當用戶存在帳號，完成帳號和密碼的輸入，點擊登陸，以下面代碼所示

store.dispatch(FetchLoginAction(context, name, password));
複製代碼

當LoginMiddleware收到該指令，觸發登陸，以下面代碼所示

Future<void> _doLogin(NextDispatcher next, BuildContext context,
      String userName, String password) async {
    next(RequestingLoginAction());

    try {
      LoginBean loginBean =
          await LoginManager.instance.login(userName, password);
      if (loginBean != null) {
        String token = loginBean.token;
        LoginManager.instance.setToken(loginBean.token, true);
        UserBean userBean = await LoginManager.instance.getMyUserInfo();
        if (userBean != null) {
          next(InitCompleteAction(token, userBean, false));
          next(ReceivedLoginAction(token, userBean));
          NavigatorUtil.goMain(context);
        } else {
          ToastUtil.showMessgae('登陸失敗請從新登陸');
          LoginManager.instance.setToken(null, true);
        }
      } else {
        ToastUtil.showMessgae('登陸失敗請從新登陸');
        next(ErrorLoadingLoginAction());
      }
    } catch (e) {
      LogUtil.v(e, tag: TAG);
      ToastUtil.showMessgae('登陸失敗請從新登陸');
      next(ErrorLoadingLoginAction());
    }
}
複製代碼

當開始登陸時，redux發出指令RequestingLoginAction加載loading界面，當登陸成功後，會對token信息進行緩存，而後在獲取用戶資料，當用戶資料獲取成功後，則判斷登陸成功，跳轉到主頁面。

主頁

主頁的頁面加載是採用TabBar+PageView(TabBarView慎用)組合加載home、repo、event、issue四個頁面，關鍵代碼以下所示

TabBar(
    controller: _tabController,
    labelPadding: EdgeInsets.all(8.0),
    indicatorColor: Colors.white,
    tabs: choices.map((Choice choice) {
         return Tab(
                    text: choice.title,
                );
         }).toList(),
    onTap: (index) {
        _pageController.jumpTo(ScreenUtil.getScreenWidth(context) * index);
    },
)

//慎用TabBarView，假如如今有四個tab，若是首次進入app以後，
//點擊issue tab，動態 tab也會觸發加載數據，而且當即銷燬
PageView(
    controller: _pageController,
    physics: NeverScrollableScrollPhysics(),
    children: <Widget>[
        BlocProvider<HomeBloc>(
            child: HomePage(),
            bloc: _homeBloc,
        ),
        BlocProvider<ReposBloc>(
            child: ReposPage(PageType.repos),
            bloc: _reposBloc,
        ),
        BlocProvider<EventBloc>(
            child: EventPage(PageType.received_event),
            bloc: _eventBloc,
        ),
        BlocProvider<IssueBloc>(
            child: IssuePage(),
            bloc: _issueBloc,
        ),
     ],
     onPageChanged: (index) {
         _tabController.animateTo(index);
     },
)

在查詢關注狀態時，須要判斷該用戶是不是本身，若是是，則不進行查詢操做

關注用戶

相關api以下所示

PUT /user/following/:username

涉及到的相關代碼以下所示

Future _follow() async {
    final response = await UserManager.instance.follow(name);
    if (response != null && response.result) {
