Complete the code to specify the Flutter version in the GitHub Actions workflow.

Flutter

uses: subosito/flutter-action@v1
  with:
    flutter-version: [1]

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using an outdated Flutter version that lacks needed features.

Leaving the version blank, causing the workflow to fail.

The flutter-version key sets the Flutter SDK version for the workflow. Using 3.7.0 ensures compatibility with recent Flutter features.

💡 Hint

Common Mistakes

Using 'flutter build' instead of 'flutter test' to run tests.

Using 'flutter analyze' which only checks code style.

The flutter test command runs unit and widget tests in your Flutter project during CI.

💡 Hint

Common Mistakes

Using 'flutter run apk' which is invalid syntax.

Using 'flutter deploy' which is not a Flutter CLI command.

The correct command to build an APK is flutter build apk --release. 'build' tells Flutter to compile the app.

Fill both blanks to set up caching for Flutter dependencies in GitHub Actions.

Flutter

- name: Cache Flutter dependencies
  uses: actions/cache@v3
  with:
    path: [1]
    key: ${{ runner.os }}-flutter-${{ hashFiles('[2]') }}

Drag options to blanks, or click blank then click option'

Cbuild

Dflutter.lock

Attempts:

💡 Hint

Common Mistakes

Caching the 'build' folder which is large and changes often.

Using a wrong lock file name like 'flutter.lock'.

Caching ~/.pub-cache speeds up dependency installation. Using pubspec.lock in the key ensures cache updates when dependencies change.

5fill in blank

Fill all three blanks to create a GitHub Actions job that checks out code, sets up Flutter, and runs tests.

Flutter

jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/[1]@v3
      - uses: subosito/flutter-action@v1
        with:
          flutter-version: [2]
      - name: Run tests
        run: flutter [3]

Drag options to blanks, or click blank then click option'

B3.7.0

Ctest

Dsetup

💡 Hint

Common Mistakes

Using 'actions/setup' instead of 'actions/checkout'.

Forgetting to specify the Flutter version.

Running 'flutter build' instead of 'flutter test' in the test step.

The actions/checkout action gets the code. Setting flutter-version to 3.7.0 installs Flutter. Running flutter test executes tests.
