Practical guide: Flutter + Firebase + Codemagic (for iOS)

In the latest Stack Overflow developer surveyFirebase was among the most lovedtechnologies in the database area. In the case you are new to Firebase, it’s a cloud-based service provided by Google to enhance mobile app development. Firebase takes the load of managing the in-house mobile application infrastructure. Firebase provides many useful services that make our lives easier, the most used services are:

  • Remote database
  • Remote config
  • Analytics
  • Authentication
  • Crash reporting (Crashlytics)

Most mobile app developers use Firebase services for a different purpose. Firebase also provides the test lab which offers test devices in the cloud for automated testing. Firebase supports both iOS and Android apps written using native technologies, such as Swift or Kotlin. On top of that, it also supports cross-platform mobile app development frameworks, such as Flutter. Firebase has official documentation on how to configure the Firebase SDK with Flutter apps. In this post, we will provide a step-by-step guide on how to set up the Firebase SDK for Flutter apps and publish those apps securely using the Codemagic CI/CD solution.

Prerequisites

In order to follow this guide, you need the following:

In this post, we will use the Codemagic-Demo app and set up Firebase plugins for the iOS version of the Flutter app. You can do a similar setup for the Android version of the Flutter app.

Firebase console: Project setup

To get started with Firebase, you need to have a Google account. Visit https://firebase.google.com/ and log in with your Google account credentials. You will be logged in to the Firebase console where you need to set up your project. Once logged in, you can create a project where you can add your iOS, Android or web apps. Detailed information about the Firebase project is available here, but we need to add the project name, project ID and accept the terms & conditions. Now, let’s create a Codemagic Demo project.

Firebase automatically assigns the project ID when the project name is entered, you can change the project ID at this stage. After this stage is complete, you cannot change the project ID anymore.

Once the project is created, you can access the dashboard of the project. Firebase has automatically provisioned all the resources required for the project.

Firebase: App setup

It’s time to add our iOS app to the Firebase project. Flutter creates both the iOS and the Android version of the app. In the Flutter app source code, you can see separate directories for the ios and android app. In order to add the app to Firebase, you have to complete the platform-specific setup. There is a separate set of instructions for Flutter projects which require fewer steps than the native apps. Let’s add the iOS version of the Flutter app to Firebase by clicking on the iOS icon in the project overview page. You will be asked to enter a few details of the iOS app, such as bundle ID, nickname and App Store ID.

Only the bundle ID is mandatory. You can get the bundle ID of the iOS app from Xcode. Open ios/Runner.xcworkspace in Xcode and click on Runner in the top left corner. You can then see the bundle identifier on the General tab of your main target.

In our case, it’s com.codemagic.demo. If you prefer the command line, you can execute the following command by passing the scheme and project workspace of your app.

$ cd ios $ xcodebuild -workspace Runner.xcworkspace/ -scheme Runner -showBuildSettings | grep PRODUCT_BUNDLE_IDENTIFIER

This will print the bundle identifier of your app. You can enter this identifier while registering the app with Firebase.

In the next step, Firebase will ask you to download the GoogleService-Info.plist file and put it in the iOS app directory. You can also download this anytime later.

In the case of iOS app setup, Firebase will guide you to create a Podfile and install pods, etc. However, you don’t have to perform these steps for the Flutter iOS app setup. Just proceed to the next steps until you see this screen.

At this stage, if you navigate the Firebase dashboard of your project, you will see that our iOS version of the Flutter app has been added to Firebase.

Similarly, you can also set up the Flutter Android app by following the instructions for Android, but we won’t go into this in this tutorial.

Google's Flutter 1.20 stable announced with new features - Navoki

Flutter Google cross-platform UI framework has released a new version 1.20 stable.

Flutter is Google’s UI framework to make apps for Android, iOS, Web, Windows, Mac, Linux, and Fuchsia OS. Since the last 2 years, the flutter Framework has already achieved popularity among mobile developers to develop Android and iOS apps. In the last few releases, Flutter also added the support of making web applications and desktop applications.

Last month they introduced the support of the Linux desktop app that can be distributed through Canonical Snap Store(Snapcraft), this enables the developers to publish there Linux desktop app for their users and publish on Snap Store.  If you want to learn how to Publish Flutter Desktop app in Snap Store that here is the tutorial.

Flutter 1.20 Framework is built on Google’s made Dart programming language that is a cross-platform language providing native performance, new UI widgets, and other more features for the developer usage.

Here are the few key points of this release:

Performance improvements for Flutter and Dart

In this release, they have got multiple performance improvements in the Dart language itself. A new improvement is to reduce the app size in the release versions of the app. Another performance improvement is to reduce junk in the display of app animation by using the warm-up phase.

sksl_warm-up

If your app is junk information during the first run then the Skia Shading Language shader provides for pre-compilation as part of your app’s build. This can speed it up by more than 2x.

Added a better support of mouse cursors for web and desktop flutter app,. Now many widgets will show cursor on top of them or you can specify the type of supported cursor you want.

Autofill for mobile text fields

Autofill was already supported in native applications now its been added to the Flutter SDK. Now prefilled information stored by your OS can be used for autofill in the application. This feature will be available soon on the flutter web.

flutter_autofill

A new widget for interaction

InteractiveViewer is a new widget design for common interactions in your app like pan, zoom drag and drop for resizing the widget. Informations on this you can check more on this API documentation where you can try this widget on the DartPad. In this release, drag-drop has more features added like you can know precisely where the drop happened and get the position.

Updated Material Slider, RangeSlider, TimePicker, and DatePicker

In this new release, there are many pre-existing widgets that were updated to match the latest material guidelines, these updates include better interaction with Slider and RangeSliderDatePicker with support for date range and time picker with the new style.

flutter_DatePicker

New pubspec.yaml format

Other than these widget updates there is some update within the project also like in pubspec.yaml file format. If you are a flutter plugin publisher then your old pubspec.yaml  is no longer supported to publish a plugin as the older format does not specify for which platform plugin you are making. All existing plugin will continue to work with flutter apps but you should make a plugin update as soon as possible.

Preview of embedded Dart DevTools in Visual Studio Code

Visual Studio code flutter extension got an update in this release. You get a preview of new features where you can analyze that Dev tools in your coding workspace. Enable this feature in your vs code by _dart.previewEmbeddedDevTools_setting. Dart DevTools menu you can choose your favorite page embed on your code workspace.

Network tracking

The updated the Dev tools comes with the network page that enables network profiling. You can track the timings and other information like status and content type of your** network calls** within your app. You can also monitor gRPC traffic.

Generate type-safe platform channels for platform interop

Pigeon is a command-line tool that will generate types of safe platform channels without adding additional dependencies. With this instead of manually matching method strings on platform channel and serializing arguments, you can invoke native class and pass nonprimitive data objects by directly calling the Dartmethod.

There is still a long list of updates in the new version of Flutter 1.2 that we cannot cover in this blog. You can get more details you can visit the official site to know more. Also, you can subscribe to the Navoki newsletter to get updates on these features and upcoming new updates and lessons. In upcoming new versions, we might see more new features and improvements.

You can get more free Flutter tutorials you can follow these courses:

What is Flutter and why you should learn it?

Flutter is an open-source UI toolkit for mobile developers, so they can use it to build native-looking** Android and iOS** applications from the same code base for both platforms. Flutter is also working to make Flutter apps for Web, PWA (progressive Web-App) and Desktop platform (Windows,macOS,Linux).

flutter-mobile-desktop-web-embedded_min

Flutter was officially released in December 2018. Since then, it has gone a much stronger flutter community.

There has been much increase in flutter developers, flutter packages, youtube tutorials, blogs, flutter examples apps, official and private events, and more. Flutter is now on top software repos based and trending on GitHub.

Flutter meaning?

What is Flutter? this question comes to many new developer’s mind.

humming_bird_dart_flutter

Flutter means flying wings quickly, and lightly but obviously, this doesn’t apply in our SDK.

So Flutter was one of the companies that were acquired by **Google **for around $40 million. That company was based on providing gesture detection and recognition from a standard webcam. But later when the Flutter was going to release in alpha version for developer it’s name was Sky, but since Google already owned Flutter name, so they rename it to Flutter.

Where Flutter is used?

Flutter is used in many startup companies nowadays, and even some MNCs are also adopting Flutter as a mobile development framework. Many top famous companies are using their apps in Flutter. Some of them here are

NuBank

Reflectly app

and many more other apps. Mobile development companies also adopted Flutter as a service for their clients. Even I was one of them who developed flutter apps as a freelancer and later as an IT company for mobile apps.
