Set up a Flutter CI flow with GitHub Actions.
What is GitHub Actions?
GitHub Actions is a system that runs automated jobs (CI) on code pushed to a GitHub repository. You define a workflow by placing a YAML file in the .github/workflows/ folder. A typical Flutter pipeline includes flutter test and flutter build steps.
name: CI
on: [push, pull_request]
jobs:
test:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v4
- uses: subosito/flutter-action@v2
- run: flutter testCI steps
A typical Flutter CI pipeline: check out code (actions/checkout), install the Flutter SDK (subosito/flutter-action), fetch dependencies (flutter pub get), run tests (flutter test), and build (flutter build apk). Each run: line is a shell command.
Practice CI steps list
In main, define a list of String CI steps in order: 'checkout', 'flutter pub get', 'flutter test', 'flutter build apk'. Print the 3rd element (index 2) with print.
Starter code
void main() {
// CI adımları listesi tanımla: checkout, flutter pub get, flutter test, flutter build apk
// listenin 3. elemanini (index 2) yazdir
}Sample solution
void main() {
final steps = <String>[
'checkout',
'flutter pub get',
'flutter test',
'flutter build apk',
];
print(steps[2]);
}Expected output
flutter test
