flutter_build_manager 1.0.15

A production-ready open-source Dart CLI package that manages Flutter releases for macOS, Windows, Linux, iOS, and Android.

flutter_build_manager

A production-ready Flutter Release Manager that automatically builds, renames, organizes, and tracks your Flutter release artifacts natively for macOS, Windows, Linux, iOS, and Android.

Why use flutter_build_manager?

Managing Flutter releases manually is tedious, error-prone, and messy. Developers often struggle with:

• Forgetting to bump version numbers.
• Losing track of which APK or IPA was sent to QA.
• Overwriting previous builds in the build/ folder.
• Inconsistent naming conventions across team members.
• Manually generating checksums and metadata for CI/CD.

flutter_build_manager solves all of these problems. It acts as an automated pipeline that strictly enforces a naming convention, dynamically tracks build counters across different environments (DEV, QA, LIVE), safely organizes output files into dated directories, and produces robust metadata and SHA256 checksums—all with a single command.

Whether you are an indie developer aiming for better organization or an enterprise team orchestrating complex CI/CD pipelines, this package brings maturity and stability to your Flutter release process.

Features

✅ Automatic release artifact naming: Stop naming files manually. Use dynamic templates. ✅ Automatic build counter: Track release sequences mathematically (e.g. 001, 002). ✅ Daily counter reset: Optionally reset your release counters every night at midnight. ✅ Environment detection: Seamlessly support DEV, QA, UAT, and LIVE tags. ✅ Flutter Flavor support: Automatically integrates with your existing Flutter --flavor setup. ✅ --dart-define support: Detects environments injected via Dart defines. ✅ FVM support: Automatically detects and uses your local .fvm Flutter SDK. ✅ Flutter SDK auto-detection: Falls back elegantly to global FVM or System Flutter. ✅ Target Support: Builds and tracks APK, AAB, and IPA natively. ✅ SHA256 generation: Automatically hashes your artifacts for security integrity. ✅ Metadata generation: Spits out a robust release.json detailing the build context. ✅ Release history: Never overwrite an artifact; safely stores logs and state counters. ✅ Preview mode: See exactly what a build will generate before you run it. ✅ Custom filename templates: Total control over the final file name. ✅ Cross-platform support: Built in native Dart to run flawlessly on macOS, Windows, and Linux.

Quick Start

Transform your messy release process into a professional pipeline in seconds:

# 1. Initialize the configuration
flutter_release init

# 2. Preview what a release will look like (does not trigger a build)
flutter_release preview

# 3. Build and package your release!
flutter_release build apk

How It Works

The manager does not simply wrap flutter build. It operates a strictly orchestrated, transactional 19-step pipeline that ensures your workspace remains pristine if an error occurs.

graph TD
    A[Read Configuration] --> B[Detect Flutter SDK]
    B --> C[Detect Project Name]
    C --> D[Read pubspec.yaml]
    D --> E[Detect Environment]
    E --> F[Generate Counter]
    F --> G[Generate Filename]
    G --> H[Build Flutter App]
    H --> I[Rename Artifacts]
    I --> J[Create Release Folder]
    J --> K[Generate Metadata]
    K --> L[Generate Checksums]
    L --> M[Update Counter]
    M --> N[Done]

Important

Transactional Rollbacks: If the pipeline fails during file generation (e.g., checksum fails), it will automatically rollback and delete the partially moved artifacts, ensuring your release directory stays perfectly clean!

---

Using with Existing Flutter Projects

Integrating flutter_build_manager into a legacy project is completely non-destructive and requires zero code changes.

1. Open project: Navigate to your Flutter project root in your terminal.
2. Run init: Execute flutter_release init.
3. Review: Check the newly generated flutter_release.yaml and adjust preferences.
4. Run preview: Execute flutter_release preview to verify filename generation.
5. Build release: Execute flutter_release build apk.

---

Using with FVM

flutter_build_manager has first-class support for Flutter Version Management (FVM).

If your project looks like this:

my_app/
  ├── .fvm/
  │    ├── fvm_config.json
  │    └── flutter_sdk/
  ├── pubspec.yaml
  └── flutter_release.yaml

The CLI will automatically detect .fvm/fvm_config.json and seamlessly route all compilation commands through your local FVM SDK.

Note

The manager adheres to strict environments: It will never fall back to the system Flutter if it detects you have configured FVM for the project but forgot to run fvm install. It will intentionally throw a helpful error instead!

---

Environment Detection

The manager automatically tags your builds with an environment (e.g. LIVE, DEV). It resolves this using a strict priority chain:

1. Flutter Flavors: If you pass --flavor dev, the environment is automatically set to DEV.
2. Dart Defines: If you pass --dart-define=ENV=QA, it resolves to QA.
3. Configuration: Uses the default configured in flutter_release.yaml.
4. Manual override: Passing --env=STAGING overrides everything else.

---

Configuration

The flutter_release.yaml file controls the entire pipeline behavior.

release_manager:
  enabled: true
  output_directory: release
  template: "{project}_{date}_{env}_{counter}"
  build_counter:
    mode: daily
  organize_by:
    date: true
    environment: true

Property	Description
enabled	Master toggle for the release manager.
output_directory	The root folder where all releases are saved.
template	The dynamic filename template string.
build_counter.mode	Either daily (resets at midnight) or continuous.
organize_by.date	Toggles for generating a single date folder (e.g. build/release/24_07_2026/LIVE/).

---

Filename Templates

Customize your artifact filenames using dynamic placeholders inside your flutter_release.yaml template string.

Placeholder	Description	Example
{project}	The name of your Flutter project	DriveReplay
{version}	The semantic version from pubspec	2.4.1
{flutter_build}	The build number from pubspec	35
{counter}	The generated release sequence counter	014
{date}	Current date (yyyyMMdd)	20260724
{time}	Current time (HHmmss)	143015
{env}	Resolved environment	LIVE
{platform}	Target platform	android
{year}	Current 4-digit year	2026
{month}	Current full month name	July

Examples

With different templates, you can output:

• DriveReplay_20260724_LIVE_001.apk
• DriveReplay_20260724_DEV_014.aab
• CRM_v2.4.1_QA_003.apk

---

Project Structure

When you execute a build, the manager safely isolates its outputs:

my_app/
  ├── .build_release/         # Internal state directory
  │    ├── state.json         # Tracks your active build counters
  │    └── logs/              # Daily execution logs
  │
  ├── build/
  │    └── release/             # Your beautiful output directory
  │         └── 24_07_2026/
  │              └── LIVE/
  │                   ├── DriveReplay_20260724_LIVE_001.apk
  │                   ├── DriveReplay_20260724_LIVE_001.apk.sha256
  │                   └── release.json

Generated Files

• release.json: A comprehensive metadata snapshot containing file sizes, Flutter/Dart SDK versions used, timestamps, and environment data. Perfect for CI/CD ingestion.
• *.sha256: A cryptographic hash file validating the absolute integrity of your artifact.
• Logs: Daily rotated logs detailing build durations and any caught exceptions.

Commands

Command	Description
flutter_release init	Scaffolds the flutter_release.yaml configuration in your project.
flutter_release preview	Simulates a build outputting the exact filenames and paths without actually compiling anything.
flutter_release build <target>	Triggers the complete compilation and packaging pipeline for apk, aab, or ipa.
flutter_release version	Displays the current CLI version and your project's parsed pubspec version.
flutter_release config	Generates or modifies the configuration securely.
flutter_release reset	Safely resets build counters.
flutter_release clean	Safely cleans generated output paths.
flutter_release doctor	Validates your system dependencies against the CLI package.

---

Release History & Build Counters

The manager uses a smart counting system to ensure you can build multiple times a day without file conflicts.

If build_counter.mode is set to daily in your config, the counters automatically reset at midnight, giving you pristine 001 files every morning. It also strictly isolates counters by environment!

Build Counter Examples:

[Today]
LIVE -> 001
LIVE -> 002
DEV  -> 001

[Tomorrow]
LIVE -> 001
DEV  -> 001

Troubleshooting

Warning

Flutter not found Ensure flutter is in your system PATH, or that you have successfully run fvm install if using FVM.

Warning

FVM not found FVM was detected in fvm_config.json, but the .fvm/flutter_sdk folder is completely missing. Run fvm install to fix it.

Warning

Malformed YAML / Missing pubspec.yaml If your flutter_release.yaml or pubspec.yaml is malformed, the pipeline will immediately halt. Run your YAML through a linter.

Warning

Permission denied Occurs if the CLI lacks write permissions to generate the release/ directory. Relaunch your terminal as an Administrator, or fix your folder ownership.

Warning

Build failed If Flutter compilation fails, the CLI will output the direct stderr logs from the compiler. Fix your Dart code and try again. The CLI guarantees it won't leave broken files in your release folder.

Warning

Invalid template An unknown variable string like {unknown} was encountered in the template key. Review your flutter_release.yaml.

FAQ

1. Does this modify my project? No. It only reads your pubspec.yaml and creates a .build_release/ and release/ folder which you can safely add to your .gitignore.

2. Can I customize filenames? Absolutely. Adjust the template key in flutter_release.yaml.

3. Does it work with FVM? Yes! First-class FVM support is natively built in.

4. Can I disable counters? Yes, simply remove {counter} from your template, though you may encounter file overwrites if you build multiple times in the same minute without {time}.

5. Does it support CI/CD? Yes. Since it is a headless Dart CLI, it is highly recommended to run flutter_release build apk inside GitHub Actions or GitLab CI.

6. Can I upload automatically? Not yet, but cloud upload integrations are on the roadmap!

7. Will it overwrite releases? Never. If a file collision occurs, it automatically appends _2, _3, etc., keeping all past releases safe.
