We’ll be adding that to the pipeline shortly. Be sure to keep your Service Account JSON file handy.

You will also want to set up a Fastlane service account while creating your Android setup. These files can then be re-added during the job with the following command: echo "$ENV_VARIABLE_NAME" | base64 -decode > You can encode them by ruinning the following command: cat | base64 -w 0 # -w 0 will ensure no newlines are present. Since one file requires newlines to be present, and another is a binary file, it’s recommended that they are base64-encoded prior to adding them as enviornment variables to preserve the data. This will allow the continuous integration pipeline to properly build and sign the application. Two things from this guide will need to be added to CircleCI as enviornment variables: the key.properties file and the key.jks file. While it can live in your home directory, having it saved to a git-ignored directory in your project will come in handy when configuring the key.properties file. Take note of where you save your key.jks file. It’s recommended to use AppBundles when building Android apps, as it allows Google to build individual APKs for different platforms while keeping filesize down. Steps for setting this up can be found here. An “upload key” is required so that Google can verify the authenticity of the app before accepting it. When publishing Android apps, there are a few requirements to satisfy before implementing Fastlane. Read more on continuous integration for mobile application development. Push it to a repository on GitHub.Įnsure that you are set up to publish apps using Google Play or the Apple App Store - steps for each will vary, so be sure to follow the steps outlined for the respective provider. We won’t be dealing much with the application itself. The default “hello world” app will suffice. Installing Flutter and creating your first app can be done by following these guides: Leveraging CircleCI and Fastlane, this is a relatively straightforward process that can be automated.

As more apps are written using it and Dart (the underlying language), it’s becoming more important to consider how developers can package and deliver their code to their users.
Flutter is a toolkit provided by Google for building cross-platform applications, including Android, iOS, and web apps.
