How to Integrate Firebase and Flutter in iOS and Android Apps?

Firebase is a fully managed backend service developed by Google. We can connect to the backend without writing any code. Firebase developers to develop Android, IOS, and Web apps. For reporting and fixing app crashes, tracking analytics, and creating marketing and product experiments, firebase provides several tools. Backend-as-a-Service (BaaS) provider Firebase was a YC11 startup.

It developed into a platform for developing next-generation apps on the Google Cloud Platform. A real-time database called Firebase (a NoSQLjSON database) enables the storage of a list of objects in a tree. Data can be synchronized between many devices. Where Realtime Database stores data within the form of a JSON, Cloud Firestore takes a way more structured approach.

Firestore keeps its data inside objects. These documents contain key-value pairs and can contain any kind of data, from strings to binary data to even objects that resemble JSON The documents, in turn, are grouped into collections.

Advantages of Firebase

  • Real-time Database Helps to Store Synchronize Data.
  • Firebase Provides a Crash Reporting Facility to Quickly Fix Bugs.
  • Fast and Secured Web Hosting.
  • Firebase Allows the Content Storage with Ease.
  • Send Messages and Notifications to Specific Audiences.

Create and Configure your Firebase Project

The first step is to create a Firebase project and configure the native Android/iOS and Flutter apps to use Firebase services.

  1. Navigate to the Firebase console.
  2. Select Add project.
  3. Type in the project name and click Continue.
  4. Continue with Enable Google Analytics for this project turned on.

Configuring an Android app

You should be able to see the project dashboard once the project has been created. To get the Android project started, do the following:

  • Select the Android icon.
  • In the Register section, enter the package name and SHA-1 key and then click Register app.
  • Place the google-services.json file in the Android app directory. This is how it should look: android/app/google-services.json
  • Install the Firebase SDK as described in the Add Firebase SDK section.
  • Continue to the console.

Creating a Flutter project

To use any Firebase service, you must first install the firebase core plugin, which allows the app to communicate with Firebase.

    dependencies:
        flutter:
            sdk: flutter
            cupertino_icons: ^1.0.2
            firebase_core: ^1.0.1

Creating a mobile application is generally a difficult and demanding undertaking. For the development of mobile applications, there are numerous frameworks available. Both iOS and Android offer native frameworks based on the Java programming language. The languages Objective-C and Shift.However, we must code in two distinct languages and use two different frameworks in order to create an application that supports both OSs. Mobile frameworks supporting both OS exist to aid in overcoming this complication.

These frameworks range from straightforward hybrid mobile application frameworks built on HTML (using HTML for the user interface and JavaScript for the application logic) to complicated language-specific frameworks (which handle the laborious task of translating code to native code). No matter how simple or complex they are, these frameworks always have a number of drawbacks.


Windows installation

Let's look at the installation process for the Flutter SDK and its prerequisites in this section for Windows systems.

Step 1: Download the most recent Flutter SDK from the website at https://flutter.dev/docs/get-started/install/windows. Version 1.2.1 and the filename flutter windows v1.2.1-stable.zip are current as of April 2019.
Step 2: In a folder, such as C:flutter, unzip the zip archive.
Step 3: Add the flutter bin directory to the system path.
Step 4: To ensure that all requirements for flutter development are met, Flutter offers a tool called Flutter Doctor.
Step 5: Running the above command will analyze the system and show its report as shown below
            Doctor summary (to see all details, run flutter doctor -v) :
            [√] Flutter ( Channel stable, v1.2.1, on Microsoft Windows [Version
            10.0.17134.706], locale en-US )
            [√] Android toolchain - develop for Android devices (Android SDK version 28.0.3)
            [√] Android Studio (version 3.2)
            [√] VS Code, 64-bit edition (version 1.29.1)
            [!] Connected device
            ! No devices are available
            ! Doctor found issues in 1 category.
            
Step 6: Install the most recent Android SDK if flutter doctor recommends it in step six.
Step 7: Install the most recent version of Android Studio if flutter doctor advises it.
Step 8: Start an Android emulator or connect an actual Android device to the computer in step 8 to complete the process.
Step 9: Install the plugins for Flutter and Dart in Android Studio in step 9. It offers a startup template for new Flutter applications, as well as the option to run and debug Flutter applications directly in the Android Studio.
