Release v1.0.2

Bug Fixes

iOS

• Fixed a crash caused by incorrect format string in auto-generated output path (%d.%s → %d.%@). This caused the app to crash or produce a malformed file path when no explicit output path was provided.
• Fixed conversion always returning nil — UIImage(named:) was incorrectly used to load images from a file path. Replaced with UIImage(contentsOfFile:).
• Fixed a potential crash from force casting method channel arguments (as!). Now uses safe casting with guard let, returning a proper FlutterError if arguments are malformed.
• Fixed silent nil return when image encoding fails — the plugin now returns a FlutterError with code conversionFailed instead of returning null to the caller with no explanation.
• Fixed output file not being created when the parent directory does not exist.

Android

• Fixed NullPointerException when BitmapFactory.decodeFile fails to decode the input file (unsupported format, corrupt file, or wrong path). Now throws a descriptive IOException.
• Fixed FileOutputStream resource leak — the stream is now properly closed using try-with-resources.
• Fixed output file not being created when the parent directory does not exist — parent directories are now created automatically with mkdirs().
• Fixed Bitmap memory leak — bitmap.recycle() is now called in a finally block after compression to release native memory immediately.

Build & Infrastructure

• Updated Android compileSdkVersion to 34.
• Updated Android Gradle Plugin to 8.2.2 and Gradle wrapper to 8.4 for Java 21 compatibility.
• Migrated example app Android build scripts to the declarative Flutter Gradle plugin (required by Flutter 3.x).
• Updated Flutter SDK constraint from >=2.5.0 to >=3.0.0.
• Bumped flutter_lints to 5.0.0.

Example App

• Replaced network download with bundled HEIC/HEIF sample files for offline testing.
• Added format selector (PNG / JPEG) and file picker to the example UI.
• Added integration tests covering real file conversion with magic byte verification.
