applyBuildInfo static method

Future<Map<String, dynamic>> applyBuildInfo()

Extracts build information from all supported Flutter platforms.

This method scans the project directory for platform-specific configuration files and extracts relevant build information such as package names and bundle identifiers.

Supported platforms and their configuration files:

• Android: android/app/build.gradle - Extracts applicationId
• iOS: ios/Runner.xcodeproj/project.pbxproj - Extracts PRODUCT_BUNDLE_IDENTIFIER
• Web: web/index.html - Extracts app name from <title> tag
• macOS: macos/Runner.xcodeproj/project.pbxproj - Extracts PRODUCT_BUNDLE_IDENTIFIER
• Windows: windows/runner/Runner.rc - Extracts FILEVERSION
• Linux: linux/CMakeLists.txt - Extracts PROJECT_NAME

Returns a map containing all extracted build information with the following keys:

• androidPackageName - Android application ID
• iosBundleId - iOS bundle identifier
• webAppName - Web application name
• macOSBundleId - macOS bundle identifier
• windowsPackageName - Windows version information
• linuxPackageName - Linux project name
