Performs a comprehensive project rename from 'barcode_scanner' to 'e_scan' (or 'eScan' for user-facing labels). This update spans all relevant files, including:
- Application IDs and bundle identifiers for Android, iOS, macOS, and Linux.
- VS Code launch configurations.
- Dart package import paths.
- Project names and titles in `pubspec.yaml`, `README.md`, and platform-specific configurations (e.g., CMakeLists, Info.plist, AndroidManifest).
- Extracts the complex `Drawer` widget from the `HomePage` into a dedicated `DrawerComponent`. This enhances modularity, improves code readability, and allows for easier reuse of the navigation drawer across the application.
- Updates iOS project configuration files (`project.pbxproj` and `contents.xcworkspacedata`) to properly integrate CocoaPods dependencies. This typically occurs after running `pod install` and includes adding Pods frameworks, build phases, and xcconfig references.
- Updates the Flutter SDK path in VS Code settings to a newer version.
