+
+#### 2.2 設定 Flutter 專案
+
+###### A. 專案環境更新
+
+1. 設定 對應的 Firebase 專案
+
+    - 指令
+       ```shell
+       flutterfire configure
+       ```
+    - 可以先觀察一下專案中加入哪些檔案
+
+2. 在 Flutter 專案中加入 `firebase_core`
+    - 指令
+       ```shell
+       flutter pub add firebase_core
+       ```
+
+###### B. `main.dart`
+
+1. 在 main function 中加入以下程式碼
+    ```dart
+    Future<void> main() async {
+        WidgetsFlutterBinding.ensureInitialized();
+        await Firebase.initializeApp(
+          options: DefaultFirebaseOptions.currentPlatform,
+        );
+   
+        runApp(const MyApp());
+    }
+    ```
+2. 新增 import
+
+   ```dart
+   import 'package:firebase_core/firebase_core.dart';
+   import 'package:firebase_database_demo/firebase_options.dart';
+   ```
+
+### 3 使用 Firebase 的功能
+
+#### 3.1 使用 Hosting
+
+1. 指令
+    ```shell
+    firebase experiments:enable webframeworks
+    firebase init hosting
+    ```
+    - 指令執行下去後，會依序看到下方幾個操作步驟
+        - 選擇要使用 hosting 的專案
+        - 會問是否使用 Flutter Web codebase，預設：Yes
+        - 選擇 server 的地區
+        - 是否使用自動部署，預設：No
+        - 可以觀察一下專案中增加的東西
+
+2. 部署
+
+    ```shell
+    firebase deploy
+    ```
+
+#### 3.2 使用 RemoteConfig
+
+##### 3.2.1 Firebase 的設定
+
+1. 先到 Firebase Project 中增加一個 `version` 的字串設定值
+
+##### 3.2.2 Flutter 的程式碼變動
+
+###### A. 專案環境更新
+
+1. 在 Flutter 專案中加入 `firebase_remote_config`
+    - 指令
+    ```shell
+    flutter pub add firebase_remote_config
+    ```
+
+###### B. `main.dart`
+
+1. 增加一個全域變數 `remoteConfig`
+    ```dart
+    // 在 main function 上面加入全域變數
+    late FirebaseRemoteConfig remoteConfig;
+
+    Future<void> main() async { 
+        //...
+    }
+    ``` 
+
+2. 加入 remote config 的初式化函式
+    ```dart
+    Future<void> main() async {
+      //...
+    }
+
+    // 加在 main function 下方
+    _initialRemoteConfig() async {  
+      await remoteConfig.setConfigSettings(RemoteConfigSettings(
+        fetchTimeout: const Duration(minutes: 1),
+        minimumFetchInterval: const Duration(hours: 1),
+      ));
+      await remoteConfig.setDefaults(const {
+        "version": "0.1.0",
+      });
+      await remoteConfig.fetchAndActivate();
+    }
+    ```
+
+3. 於 main() 中初始化
+    ```dart
+    Future<void> main() async {
+      //...
+      remoteConfig = FirebaseRemoteConfig.instance;
+      await _initialRemoteConfig();
+      runApp(const MyApp());
+    }
+        
+    _initialRemoteConfig() async {  
+          //...
+    }
+    ```
+
+###### C. `home_page.dart`
+
+1. 在 _HomePageState 中，加入變數呼叫
+    ```dart
+    WidgetsBinding.instance.addPostFrameCallback((_) {
+      setState(() {
+        _version = remoteConfig.getString("version");
+      });
+    });
+    ``` 
+
+#### 3.3 使用 Realtime Database
+
+#### 3.3.1 Firebase 的設定
+
+1. 先到 Firebase Project 中增加一個 `counter` 的數值
+2. 先確認規則(rule)，測試開發階段先開啟，日後要記得調回來
+
+      ```json
+      {
+      /* Visit https://firebase.google.com/docs/database/security to learn more about security rules. */
+        "rules": {
+          ".read": true,
+          ".write": true
+        }
+      }
+      ```
+
+#### 3.3.2 Flutter 的程式碼變動
+
+###### A. 專案環境更新
+
+1. 設定完畢後，回到 Flutter 專案來執行 firebase_opetions 更新
+    - 指令
+    ```shell
+    flutterfire configure
+    ```
+2. 為專案加入 `firebase_database`
+    - 指令
+       ```shell
+       flutter pub add firebase_database
+       ```
+
+###### B. 程式碼變動：`home_page.dart`
+
+1. 取出資料
+    - 加入 `_getCounterFromRealtimeDatabase`
+      ```dart
+      _getCounterFromRealtimeDatabase() async {
+        DatabaseReference ref = FirebaseDatabase.instance.ref();
+        final snapshot = await ref.child("counter").get();
+        if (snapshot.exists) {
+          setState(() {
+            _counter = snapshot.value as int;
+          });
+        }
+      }
+      ``` 
+    - 於 initState() 中加入呼叫
+      ```dart
+      WidgetsBinding.instance.addPostFrameCallback((_) {
+        setState(() {
+          _version = remoteConfig.getString("version");
+        });
+        // 加入呼叫
+        _getCounterFromRealtimeDatabase();
+      });
+      ``` 
+2. 更新資料
+    - 在 _increaseCounter() 中加入下方程式碼
+       ```dart
+       WidgetsBinding.instance.addPostFrameCallback((_) {
+         setState(() {
+           _version = remoteConfig.getString("version");
+         });
+         // 加入更新
+         DatabaseReference ref = FirebaseDatabase.instance.ref();
+         ref.update({"counter": _counter});
+       });
+       ``` 
+
+#### 3.4 使用 Firestore
+
+#### 3.4.1 Firebase 的設定
+
+1. 建立資料庫
+    - 「位置」選擇離服務當地最近者。
+    - 要注意設定後無法變更。
+2. 注意一下「規則」
+3. 新增資料集合
+    - 集合 ID：`news`
+    - 文件 ID：用序號
+        - 欄位：`title`
+        - 欄位：`content`
+    - 資料就麻煩各位自行隨便找一下新聞的標題跟內容嘍
+
+#### 3.4.2 Flutter 的程式碼變動
+
+###### A. 專案環境更新
+
+- 為專案加入 `cloud_firestore`
+    - 指令
+       ```shell
+       flutter pub add cloud_firestore
+       ```
+
+###### B. 程式碼變動：`news_page.dart`
+
+1. 宣告並初始化 FirebaseFirestore
+    ```dart
+    final FirebaseFirestore _db = FirebaseFirestore.instance;
+    ```
+2. 取得資料，修改 _initialNewsList
+    - 將原本迴圈的程式碼改成
+    ```dart
+    final collectionRef = _db.collection("news");
+    collectionRef.get().then((querySnapshot) {
+      for (QueryDocumentSnapshot docSnapshot in querySnapshot.docs) {
+        Map<String, dynamic> snapshot = docSnapshot.data() as Map<String, dynamic>;
+        final News news = News(title: snapshot["title"] ?? "", context: snapshot["content"]);
+        setState(() {
+          _list.add(news);
+        });
+      }
+    });
+    ```
+3. 新增資料，修改 _createPost
+    ```dart
+    _createPost() {
+      // 新增一筆資料
+      if (_titleController.text.isEmpty && _contentController.text.isEmpty) {
+        return;
+      }
+      final News news = News(title: _titleController.text, context: _contentController.text);
+      final collectionRef = _db.collection("news");
+      int id = _list.length + 1;
+      collectionRef.doc(id.toString()).set({"title": news.title, "content": news.context}).then((value) {
+        setState(() {
+          _list.insert(0, news);
+        });
+      }).catchError((error) {
+        print(error.toString());
+      });
+    }
+    ```
+4. 排序
+    - Firestore 的階層為 collection > document > 文件中的欄位
+    - 因此需指定
+        - .orderBy("欄位名稱")
+        - 如果要反序：.orderBy("欄位名稱", descending: true)
+    - 部份程式碼的完整範例如下
+        ```dart
+        final collectionRef = _db.collection("news");
+        collectionRef.orderBy("title", descending: true).get().then((querySnapshot) {
+        for (QueryDocumentSnapshot docSnapshot in querySnapshot.docs) {
+            Map<String, dynamic> snapshot = docSnapshot.data() as Map<String, dynamic>;
+            final News news = News(title: snapshot["title"] ?? "", context: snapshot["content"]);
+            setState(() {
+            _list.add(news);
+          });
+          }
+        });
+        ```
