• Run integrated tests
• Generate and upload an APK file

Create our Flutter example app

Before creating our workflow we need one app, and for now, the default template is enough

Flutter default app

Next, create a new GitHub repository and push all the code to it.

Git Hub Actions

A GitHub Action is a free CI/CD platform that allows workflow creation for building, testing, publishing, and many other possibilities completely integrated with GitHub.

Users can collaboratively create and share new actions on the platform which is a smart and efficient way of promoting collaboration and code reuse.

Creating a GitHub Action for your Flutter app is simple and straightforward, and it could be done in seconds, so let’s create our workflow, and then I will explain it step by step how it works:

First, create the .github/workflows/main.yml file, and paste the code below on it:

name: Flutter Workflow

on: [push, workflow_dispatch]
jobs:
  build:
    runs-on: macos-latest
    steps:
      - name: Checkout code
        uses: actions/checkout@v3

      - name: Install Flutter
        uses: subosito/flutter-action@v2
        with:
          flutter-version: '2.10.0'
          channel: 'stable'
