flutter_audit 1.0.2

Static analysis CLI for Flutter projects. Audits performance, memory safety, security, API hygiene, architecture, UI quality, and code quality in one shot.

flutter_audit examples

Two tiny Flutter-style projects used to demonstrate the auditor on both ends of the spectrum.

Note: these are scan targets, not runnable Flutter apps. They have no platform folders and don't depend on the Flutter SDK — flutter run will not work here. They exist only so flutter_audit has Dart source to analyze.

clean_project — passes the audit (0 issues)

Every widget that can be const already is, no secrets, no leaks, no hardcoded URLs, no inline styles.

dart run bin/flutter_audit.dart scan example/clean_project

Expected:

✓ Found 0 issues
Architecture Score : 100 / 100  EXCELLENT
Performance Score  : 100 / 100  EXCELLENT
Memory Safety      : 100 / 100  EXCELLENT
UI Quality         : 100 / 100  EXCELLENT
API Hygiene        : 100 / 100  EXCELLENT
Security Score     : 100 / 100  EXCELLENT
Code Quality       : 100 / 100  EXCELLENT
OVERALL            : 100 / 100  EXCELLENT

issues_project — fails the audit (~100 issues across all 7 categories)

Intentionally exercises every rule: hardcoded secrets, plaintext SharedPreferences for tokens, plain-HTTP URLs, undisposed controllers, an unclosed StreamController, missing-const widgets everywhere, a 200-line build method, deep nesting, print in production, forEach with closures, inline TextStyles, TODOs, an empty catch block, etc.

dart run bin/flutter_audit.dart scan example/issues_project

Expected (numbers may shift slightly as rules tune up):

✓ Found ~100 issues
Architecture Score : 91 / 100  EXCELLENT
Performance Score  :  0 / 100  POOR
Memory Safety      : 75 / 100  FAIR
UI Quality         : 87 / 100  GOOD
API Hygiene        : 94 / 100  EXCELLENT
Security Score     : 68 / 100  NEEDS WORK
Code Quality       : 94 / 100  EXCELLENT
OVERALL            : 70 / 100  FAIR

Top finding is a CRITICAL hardcoded_secret from lib/services/auth_service.dart.

Output formats

# Pretty terminal (default)
dart run bin/flutter_audit.dart scan example/issues_project

# JSON for CI/scripts
dart run bin/flutter_audit.dart scan example/issues_project \
    --output=json --report-file=audit.json

# Self-contained HTML dashboard
dart run bin/flutter_audit.dart scan example/issues_project \
    --output=html --report-file=example/issues_project_report.html
open example/issues_project_report.html

Pre-generated HTML reports live next to this README:

• clean_project_report.html — passes everything
• issues_project_report.html — fails 6 categories

Run both back-to-back to see the auditor produce a clean report and a dirty one from the same tool.
