tryReadImageFromPath method

Future<({ImageWithDimensions image, String path})?> tryReadImageFromPath(String text)

Try to find and read an image file, falling back to clipboard search.

Implementation

Future<({String path, ImageWithDimensions image})?> tryReadImageFromPath(
  String text,
) async {
  final cleanedPath = asImageFilePath(text);
  if (cleanedPath == null) return null;

  Uint8List? imageBuffer;

      imageBuffer = await File(cleanedPath).readAsBytes();
    } else {
      final clipboardPath = await getImagePathFromClipboard();
      if (clipboardPath != null &&
          cleanedPath == clipboardPath.split('/').last) {
        imageBuffer = await File(clipboardPath).readAsBytes();
      }
    }
  } catch (e) {
    _logError(e);
    return null;
  }

  if (imageBuffer == null || imageBuffer.isEmpty) return null;

  final ext = cleanedPath.split('.').last.toLowerCase();
  final buffer = Uint8List.fromList(imageBuffer);
  final resized = await maybeResizeAndDownsampleImageBuffer(
    buffer,
    buffer.length,
    ext.isEmpty ? 'png' : ext,
  );
  final base64Image = base64Encode(resized.buffer);
  final mediaType = detectImageFormatFromBase64(base64Image);

  return (
    path: cleanedPath,
    image: ImageWithDimensions(
      base64: base64Image,
      mediaType: mediaType.value,
      dimensions: resized.dimensions,
    ),
