firedoctor 0.1.0-beta.3

Firebase diagnostics tool for Flutter. Automatically detects misconfigurations across Android, iOS, FCM, and Crashlytics with deterministic exit codes.

FireDoctor

FireDoctor is a CLI tool that diagnoses Firebase configuration and setup issues in Flutter projects. It scans your project's structure, dependencies, platform configuration files (Android & iOS), Firebase Core initialization, Firebase Cloud Messaging (FCM) setup, and Crashlytics integration — reporting issues, computing a health score, and providing actionable recommendations.

Designed for CI/CD pipelines with deterministic exit codes, threshold flags, and machine-readable JSON output.

Quick Installation

dart pub global activate --source path .

Or from pub.dev:

dart pub global activate firedoctor

Quick Usage

# Lightweight diagnostics
firedoctor diagnose

# Full health check with health score
firedoctor doctor

# Generate JSON report
firedoctor report --json

# Save report to file
firedoctor report --output report.json

# Fail CI on warnings or above
firedoctor doctor --fail-on warning

# Require minimum health score of 80
firedoctor doctor --min-score 80

Features

• 7 Analyzers — Project structure, dependencies, Firebase Core, Android, iOS, FCM, and Crashlytics
• 56 Diagnostic Codes — Granular issue detection with info, warning, error, and critical severity levels
• Health Score Engine — Category-level scoring, priority grouping, weighted recommendations
• CI/CD Ready — Deterministic exit codes (0–4), --fail-on and --min-score thresholds
• JSON Report — Machine-readable output with full schema (schemaVersion, analyzerResults, categoryScores, recommendations)
• Cross-Platform — Works on macOS, Linux, and Windows
• ANSI Terminal — Colorized output with NO_COLOR support

Example Output

Recommendations:
  1. Add google-services.json to android/app/
  2. Add GoogleService-Info.plist to ios/Runner/
  3. Add firebase_core dependency to pubspec.yaml

CI/CD Integration

# Fail pipeline if any error-level issues found
firedoctor doctor --fail-on error

# Fail pipeline if health score drops below 75
firedoctor doctor --min-score 75

# Generate JSON report for downstream processing
firedoctor report --json > firedoctor-report.json

Exit codes: 0 (passed), 1 (warnings), 2 (errors), 3 (critical), 4 (internal failure).

See the CI/CD integration guide for detailed CI setup examples.
