Flutter Post-Build Organizer

pub package License: MIT

A powerful and configurable command-line tool to automatically rename and organize your Flutter build artifacts (APKs and AABs) after the build process is complete.

About

The flutter build command produces predictably named files (e.g., app-release.apk, app-release.aab). This tool runs after the build to:

  • Rename artifacts using your own naming convention
  • Append version information automatically
  • Organize outputs into a clean directory

All without touching Gradle or writing custom scripts.

Features

  • Rename APKs & AABs

    • APKs and App Bundles are automatically renamed using your package name and build metadata.

  • Versioned Output

    • Automatically appends version from pubspec.yaml

      my_app_1.2.2_a64.apk

  • Architecture-Aware Naming

    • armeabi-v7a → v7a
    • arm64-v8a → a64
    • x86_64 → x86
    • universal APK → uni
    • app bundle → bundle

  • Selective Artifact Filtering

    • Skip specific APK variants using discard rules.

  • Organized Output Directory

    • Move or copy artifacts into a clean folder like ./release.

  • Copy or Move

    • Preserve original build artifacts if needed.

  • Automatic Cleanup

    • Optionally delete the build/ folder after processing.

  • Safe File Handling

    • Cross-device safe operations (fallback copy + delete)
    • Prevents overwriting existing files

  • Simple Configuration

    • Everything configured via pubspec.yaml

Installation

You can install the tool globally (recommended) or as a development dependency.

dart pub global activate flutter_post_build

Option B: Dev Dependency

flutter pub add --dev flutter_post_build

Configuration

Add this block to your project's pubspec.yaml:

flutter_post_builder:
  # (Required) Base name for generated artifacts
  package_name: "my_app"

  # (Optional) Append version from pubspec.yaml (default: true)
  append_version: true

  # (Optional) Output directory
  final_directory: "./release"

  # (Optional) Move or copy files (default: true)
  move_files: true

  # (Optional) Skip specific APK variants
  discard:
    v7a: false
    a64: false
    x86: false
    uni: false

  # (Optional) Delete build folder after processing
  clean_build_folder: true

Usage

1. Build your Flutter app

flutter build apk --split-per-abi

Universal APK

flutter build apk

App Bundle

flutter build appbundle

2. Run the Post-Build Tool

If installed globally:

flutter_post_build

If installed as dev dependency:

dart run flutter_post_build

Example Output

Input:

app-armeabi-v7a-release.apk
app-arm64-v8a-release.apk
app-x86_64-release.apk
app-release.apk
app-release.aab

Output:

my_app_1.2.2_v7a.apk
my_app_1.2.2_a64.apk
my_app_1.2.2_x86.apk
my_app_1.2.2_uni.apk
my_app_1.2.2_bun.aab

Notes

  • APK and AAB builds are handled independently (as per Flutter build commands).
  • discard applies only to APK variants, not App Bundles.
  • If a file already exists in the target directory, it will be skipped.
