./gradlew app:assembleAndroidTest
# Build a debug APK, passing in the integration test file
./gradlew app:assembleDebug -Ptarget="$FCI_BUILD_DIR/integration_test/main.dart"
# Go back to the root of the project
popd

# Run the Flutter integration tests as if they were regular Android instrumentation tests
