Flutter provides many advanced packages to work with databases. The most important packages are −

  • sqflite − Used to access and manipulate SQLite database, and

  • firebase_database − Used to access and manipulate cloud hosted NoSQL database from Google.

In this chapter, let us discuss each of them in detail.

SQLite

SQLite database is the de-facto and standard SQL based embedded database engine. It is small and time-tested database engine. sqflite package provides a lot of functionality to work efficiently with SQLite database. It provides standard methods to manipulate SQLite database engine. The core functionality provided by sqflite package is as follows −

  • Create / Open (openDatabase method) a SQLite database.

  • Execute SQL statement (execute method) against SQLite database.

  • Advanced query methods (query method) to reduce to code required to query and get information from SQLite database.

Let us create a product application to store and fetch product information from a standard SQLite database engine using sqflite package and understand the concept behind the SQLite database and sqflite package.

  • Create a new Flutter application in Android studio, product_sqlite_app.

  • Replace the default startup code (main.dart) with our product_rest_app code.

  • Copy the assets folder from product_nav_app to product_rest_app and add assets inside the *pubspec.yaml` file.

  • Configure sqflite package in the pubspec.yaml file as shown below −

Use the latest version number of sqflite in place of any

  • Configure path_provider package in the pubspec.yaml file as shown below −

Flutter Web Xampp

  • Here, path_provider package is used to get temporary folder path of the system and path of the application. Use the latest version number of sqflite in place of any.

  • Android studio will alert that the pubspec.yaml is updated.

  • Click Get dependencies option. Android studio will get the package from Internet and properly configure it for the application.

  • In database, we need primary key, id as additional field along with Product properties like name, price, etc., So, add id property in the Product class. Also, add a new method, toMap to convert product object into Map object. fromMap and toMap are used to serialize and de- serialize the Product object and it is used in database manipulation methods.

  • Create a new file, Database.dart in the lib folder to write SQLite related functionality.

  • Import necessary import statement in Database.dart.

  • Note the following points here −

    • async is used to write asynchronous methods.

    • io is used to access files and directories.

    • path is used to access dart core utility function related to file paths.

    • path_provider is used to get temporary and application path.

    • sqflite is used to manipulate SQLite database.

  • Create a new class SQLiteDbProvider

  • Declare a singleton based, static SQLiteDbProvider object as specified below −

  • SQLiteDBProvoider object and its method can be accessed through the static db variable.

  • Create a method to get database (Future option) of type Future<Database>. Create product table and load initial data during the creation of the database itself.

  • Here, we have used the following methods −

    • getApplicationDocumentsDirectory − Returns application directory path

    • join − Used to create system specific path. We have used it to create database path.

    • openDatabase − Used to open a SQLite database

    • onOpen − Used to write code while opening a database

    • onCreate − Used to write code while a database is created for the first time

    • db.execute − Used to execute SQL queries. It accepts a query. If the query has placeholder (?), then it accepts values as list in the second argument.

  • Write a method to get all products in the database −

  • Here, we have done the following −

    • Used query method to fetch all the product information. query provides shortcut to query a table information without writing the entire query. query method will generate the proper query itself by using our input like columns, orderBy, etc.,

    • Used Product’s fromMap method to get product details by looping the results object, which holds all the rows in the table.

  • Write a method to get product specific to id

  • Here, we have used where and whereArgs to apply filters.

  • Create three methods - insert, update and delete method to insert, update and delete product from the database.

  • The final code of the Database.dart is as follows −

  • Change the main method to get the product information.

  • Here, we have used the getAllProducts method to fetch all products from the database.

  • Run the application and see the results. It will be similar to previous example, Accessing Product service API, except the product information is stored and fetched from the local SQLite database.

Cloud Firestore

Firebase is a BaaS app development platform. It provides many feature to speed up the mobile application development like authentication service, cloud storage, etc., One of the main feature of Firebase is Cloud Firestore, a cloud based real time NoSQL database.

Flutter Xampp Login

Flutter provides a special package, cloud_firestore to program with Cloud Firestore. Let us create an online product store in the Cloud Firestore and create a application to access the product store.

  • Create a new Flutter application in Android studio, product_firebase_app.

  • Replace the default startup code (main.dart) with our product_rest_app code.

  • Copy Product.dart file from product_rest_app into the lib folder.

  • Copy the assets folder from product_rest_app to product_firebase_app and add assets inside the pubspec.yaml file.

  • Configure cloud_firestore package in the pubspec.yaml file as shown below −

  • Here, use the latest version of the cloud_firestore package.

  • Android studio will alert that the pubspec.yaml is updated as shown here −

  • Click Get dependencies option. Android studio will get the package from Internet and properly configure it for the application.

  • Create a project in the Firebase using the following steps −

    • Create a Firebase account by selecting Free plan at https://firebase.google.com/pricing/.

    • Once Firebase account is created, it will redirect to the project overview page. It list all the Firebase based project and provides an option to create a new project.

    • Click Add project and it will open a project creation page.

    • Enter products app db as project name and click Create project option.

    • Go to *Firebase console.

    • Click Project overview. It opens the project overview page.

    • Click android icon. It will open project setting specific to Android development.

    • Enter Android Package name, com.tutorialspoint.flutterapp.product_firebase_app.

    • Click Register App. It generates a project configuration file, google_service.json.

    • Download google_service.json and then move it into the project’s android/app directory. This file is the connection between our application and Firebase.

    • Open android/app/build.gradle and include the following code −

  • Open android/build.gradle and include the following configuration −

    Here, the plugin and class path are used for the purpose of reading google_service.json file.

    • Open android/app/build.gradle and include the following code as well.

    This dependency enables the android application to use multiple dex functionality.

    • Follow the remaining steps in the Firebase Console or just skip it.

  • Create a product store in the newly created project using the following steps −

    • Go to Firebase console.

      Acronis true image

    • Open the newly created project.

    • Click the Database option in the left menu.

    • Click Create database option.

    • Click Start in test mode and then Enable.

    • Click Add collection. Enter product as collection name and then click Next.

    • Enter the sample product information as shown in the image here −

  • Add addition product information using Add document options.

  • Open main.dart file and import Cloud Firestore plugin file and remove http package.

  • Remove parseProducts and update fetchProducts to fetch products from Cloud Firestore instead of Product service API.

  • Here, Firestore.instance.collection method is used to access product collection available in the cloud store. Firestore.instance.collection provides many option to filter the collection to get the necessary documents. But, we have not applied any filter to get all product information.

  • Cloud Firestore provides the collection through Dart Stream concept and so modify the products type in MyApp and MyHomePage widget from Future<list<Product>> to Stream<QuerySnapshot>.

  • Change the build method of MyHomePage widget to use StreamBuilder instead of FutureBuilder.

  • Here, we have fetched the product information as List<DocumentSnapshot> type. Since, our widget, ProductBoxList is not compatible with documents, we have converted the documents into List<Product> type and further used it.

  • Finally, run the application and see the result. Since, we have used the same product information as that of SQLite application and changed the storage medium only, the resulting application looks identical to SQLite application application.
