integration_test/app_test.dart:1

• avoid_print is enabled (analysis_options.yaml sets avoid_print: true), but these test logs use print. Replace with debugPrint, a logging utility, or add // ignore: avoid_print only where necessary to prevent pervasive lint violations.

Comments suppressed due to low confidence (2)

integration_test/app_test.dart:1

• Printing directly conflicts with the newly enforced avoid_print lint (analysis_options.yaml sets avoid_print: true). Replace these print calls with a logging mechanism (e.g., debugPrint guarded, a logger package) or add targeted // ignore: avoid_print comments if strictly necessary for test diagnostics.

import 'dart:io';

.github/workflows/release.yml:1

• The if conditions use env.ANDROID_KEYSTORE_BASE64, but step-level env definitions are not available at evaluation time, causing these steps to always skip. Use if: secrets.ANDROID_KEYSTORE_BASE64 != '' (and similarly reference secrets.*) or define the secret at the job/workflow env level before the condition.

The email regex restricts top-level domains to 2–4 characters, incorrectly rejecting valid domains (e.g., .museum, .travel). Consider loosening the pattern (e.g., using [A-Za-z]{2,63}) or using a simpler contains('@') + '.' check appropriate for UI validation.

Suggested change

	final emailRegex = RegExp(r'^[\w.-]+@[\w.-]+\.[A-Za-z]{2,}$');
	final emailRegex = RegExp(r'^[\w-\.]+@([\w-]+\.)+[A-Za-z]{2,63}$');

The analysis options enable avoid_print, so these print statements will trigger lints and may fail flutter analyze with --fatal-infos. Replace with debugPrint(), a logging utility, or add // ignore: avoid_print selectively for test diagnostics.

Suggested change

	print('⏭️ Skipping app-specific tests - dart_wing submodule not available');
	return;
	}
	try {
	// Only attempt to test the main app if submodule is available
	// This would import and test the actual app entry point
	print('✅ Submodule available - app-specific tests could run here');
	// TODO: Add actual app tests when submodule is consistently available
	} catch (e) {
	print('⚠️ App-specific test failed (expected without full dependencies): $e');
	debugPrint('⏭️ Skipping app-specific tests - dart_wing submodule not available');
	return;
	}
	try {
	// Only attempt to test the main app if submodule is available
	// This would import and test the actual app entry point
	debugPrint('✅ Submodule available - app-specific tests could run here');
	// TODO: Add actual app tests when submodule is consistently available
	} catch (e) {
	debugPrint('⚠️ App-specific test failed (expected without full dependencies): $e');

The script commits formatting changes but never pushes them, so the repository will not receive the updates despite the comment 'commit it back'. Add a git push (e.g., git push origin HEAD) after committing.

Suggested change

	echo "✅ Formatting changes committed"
	echo "✅ Formatting changes committed"
	git push origin HEAD

The check looks for build-skipped.info, but the build job creates build-skipped-.txt files (e.g., build-skipped-debug.txt). This mismatch prevents graceful skipping and forces a failure when builds are intentionally skipped. Align the filename pattern or create the expected build-skipped.info marker.

env.FLUTTER_VERSION is referenced but never defined in the workflow, resulting in a blank value in release notes. Either set an environment variable (e.g., by capturing flutter --version) or remove the placeholder.

[Copilot]

Using a separate integration_test_driver with integrationDriver() is an older pattern; current Flutter tooling supports running integration tests directly via flutter test integration_test/ without a driver file. Consider removing this file and adjusting CI to use the newer approach for simpler maintenance.

Suggested change

	import 'package:integration_test/integration_test_driver.dart';
	Future<void> main() => integrationDriver();

The URL rewrite uses a GitHub-style x-access-token pattern which may not authenticate against Azure DevOps; Azure DevOps typically expects a PAT in the form https://:@dev.azure.com/... or credential helper usage. This likely contributes to submodule checkout failures. Adjust to a supported Azure DevOps authentication format.

Suggested change

	git config --global url."https://x-access-token:${{ inputs.submodule-token }}@farheapsolutions.visualstudio.com/".insteadOf "https://farheapsolutions.visualstudio.com/"
	git config --global url."https://AzureDevOps:${{ inputs.submodule-token }}@farheapsolutions.visualstudio.com/".insteadOf "https://farheapsolutions.visualstudio.com/"

These COPY directives make the build fail when APK artifacts are absent (e.g., when builds are intentionally skipped). To avoid hard failures, either conditionally build the image only when APKs exist, switch to a multi-stage build that copies if present, or replace COPY with ADD wrapped by a build ARG / target controlling execution.

Suggested change

	# Copy APK files from build context
	# These will be copied from build/app/outputs/flutter-apk/ during CI
	COPY build/app/outputs/flutter-apk/dartwing-debug.apk /apks/debug/
	COPY build/app/outputs/flutter-apk/dartwing-release-unsigned.apk /apks/release/
	# Optionally copy APK files from build context if present
	# Controlled by build ARG INCLUDE_APKS (default: true)
	ARG INCLUDE_APKS=true
	RUN if [ "$INCLUDE_APKS" = "true" ] && [ -f build/app/outputs/flutter-apk/dartwing-debug.apk ]; then \
	cp build/app/outputs/flutter-apk/dartwing-debug.apk /apks/debug/; \
	else \
	echo "No debug APK to copy"; \
	fi
	RUN if [ "$INCLUDE_APKS" = "true" ] && [ -f build/app/outputs/flutter-apk/dartwing-release-unsigned.apk ]; then \
	cp build/app/outputs/flutter-apk/dartwing-release-unsigned.apk /apks/release/; \
	else \
	echo "No release APK to copy"; \
	fi
