app_info_extractor 1.0.0

A Flutter plugin to extract metadata, version, and signatures from installed applications.

app_info_extractor

A pure Dart library to extract deep metadata from Android (.apk, .aab) and iOS (.ipa) binaries.

This package is designed for CI/CD tools, app managers, or developers who need to inspect app bundles without using native Android/iOS tools (like aapt or xcrun).

Features

• ✅ Universal Support: Works with APK, AAB (Android App Bundle), and IPA.
• ✅ App Metadata: Extract Package Name, Version Name, Version Code, and App Label.
• ✅ SDK Info: Get Min SDK, Target SDK, and Compile SDK versions.
• ✅ Permissions: List all requested permissions (Android) or Usage Descriptions (iOS).
• ✅ Icon Extraction: Smartly hunts for the highest resolution PNG/WebP icon or returns raw bytes for Android Vector Drawables.
• ✅ No Native Dependencies: Written in 100% pure Dart. Works on Windows, macOS, Linux, and Web (with file upload).

Usage

import 'package:app_info_extractor/app_info_extractor.dart';

void main() async {
  final metadata = AppInfoExtractor.extract('path/to/your/app.apk');

  print('App Name: ${metadata.applicationLabel}');
  print('Package: ${metadata.applicationId}');
  print('Version: ${metadata.versionName} (${metadata.versionCode})');

  if (metadata.iconBytes != null) {
    // In Flutter, you can display this immediately:
    // Image.memory(metadata.iconBytes!)
    print('Icon extracted: ${metadata.iconBytes!.length} bytes');
  }
}

How Icon Extraction Works

Since modern Android apps use Vector XML icons, this package uses a priority-based hunt:

1. Official Pointer: Resolves the android:icon resource path.

2. Heuristic Search: Scans for high-res PNGs in mipmap or drawable folders.

3. Asset Fallback: For Flutter apps, it scans the asset bundle for branded logos.

Dependencies

• archive: For ZIP extraction.

• protobuf: For AAB manifest and resource parsing.

• plist_parser: For iOS Info.plist decoding.
