processWithImageToByteData method

@override Future<ByteData?> processWithImageToByteData(Uint8List imageData, int width, int height)

Implementation

@override
Future<ByteData?> processWithImageToByteData(Uint8List imageData, int width, int height) async {
    try {
        final result = await methodChannel.invokeMethod('processWithImageToByteData', {
            'imageData': imageData,
            'width': width,
            'height': height,
        });

        if (result == null) {
            return null;
        }

        final List<int> resultList = result as List<int>;

        if (resultList.isEmpty) {
            return null;
        }

        final expectedSize = width * height * 4; // RGBA format
        if (resultList.length != expectedSize) {
            return null;
        }

        // 直接使用 resultList 创建 ByteData，避免创建额外的 Uint8List
        return ByteData.view(Uint8List.fromList(resultList).buffer);
    } catch (e) {
        print('Error in processWithImageToByteData: $e');
        return null;
    }
